Software Support Added in IRIX 6.5.1 through IRIX 6.5.23

Feature Stream Only

Introduced in IRIX 6.5.21f:

In the IRIX 6.5.21f release, the output to the XVM show command indicates whether an XVM physical volume (physvol) has no physical connection to the system. This indicates that an I/O error would be returned when trying to read or write anywhere on the volume.

Introduced in IRIX 6.5.20f:

IRIX 6.5.20f provides the following options for the CXFS and XVM Manager GUIs:
- New GUI login choices, including support for a remote shell connection, which connects to the server via a user-specified command shell, such as rsh(1C) or ssh(1).
- The ability for the root user to grant other users permission to execute specific GUI tasks.
In IRIX 6.5.20f, the default values for cxfsd_min and cxfsd_max have changed to 16. The legal value for cxfsd_max has also changed to be an integer in the range 8 through 4096.

Introduced in IRIX 6.5.19f:

CXFS upgrades
- A new rolling annual upgrade policy permits you to upgrade from IRIX 6.5.n to the n+1 or n+4 release. This policy takes effect as of IRIX 6.5.18f.
- The time required to update and propagate the database across nodes in the cluster has been significantly decreased.
- If you use I/O fencing and ipfilterd(1M) on a node, the ipfilterd configuration must allow communication between the node and the telnet(1) port on the switch.
- The CXFS Manager graphical user interface (GUI) has added a new icon to represent client-only nodes. In preparation for future CXFS MultiOS client releases, the CXFS software now also allows you to specify the Linux, IBM AIX, and Hewlett-Packard HP-UX operating systems when defining a node.
- Application programmers should be aware that XFS recently relaxed the requirement that direct I/O be aligned along filesystem block boundaries. As of IRIX 6.5.19f, direct I/O will also be accepted using 512-byte alignment. This change makes the use of direct I/O on a CXFS partition more consistent with that of other vendors requirements and thus makes the use of CXFS more transparent. See the description of direct I/O requirements in the fcntl(2) man page.
For details, see the SGI InfiniteStorage CXFS Administration Guide.

Introduced in IRIX 6.5.18f:

In IRIX 6.5.18f, the CXFS Manager graphical user interface (GUI) has been enhanced to contain all of the XVM GUI functionality. Using the CXFS GUI in IRIX 6.5.18f or later release, you can view and configure CXFS filesystems as well as use drag-and-drop to structure volume topologies and administer XVM disks. Command buttons provide shortcuts to some tasks.
For information on the CXFS GUI, see SGI InfiniteStorage CXFS Administration Guide. For details about XVM volume management, see the XVM Volume Manager Administrator's Guide.
The XVM snapshot feature provides the ability to create virtual point-in-time images of a filesystem without causing a service interruption. The snapshot feature requires a minimal amount of storage because it uses a copy-on-write mechanism that copies only the data areas that change after the snapshot is created. The XVM snapshot feature is supported in the CXFS XVM GUIs.
For information on the XVM snapshot feature, see the XVM Volume Manager Administrator's Guide.
Use of the XVM snapshot features requires a FLEXlm license.
In an environment without cluster services enabled, you can set up and administer logical volumes with the XVM Manager GUI as a standalone product. For information on XVM volume management, see the XVM Volume Manager Administrator's Guide.
As of 6.5.18f, IRIX nodes may now be CXFS client-only nodes, meaning that they run a minimal implementation of the CXFS and cluster services, and do not contain a copy of the CXFS cluster database. Client-only nodes are installed with the cxfs_client software product.
Nodes that you want to run as potential metadata servers must be installed with the cluster_admin software product, allowing the node to perform cluster administration tasks and contain a copy of the cluster database. They must also be defined as metadata server-capable administration nodes.
A CXFS cluster is now supported with as many as 32 nodes. As many as 16 of those nodes can be CXFS administration nodes and all other nodes can be client-only nodes. SGI strongly recommends that only potential metadata servers be configured as CXFS server-capable administration nodes and that there be an odd number of server-capable nodes for quorum calculation purposes.
In IRIX 6.5.18f, CXFS relocation is disabled by default and CXFS recovery is supported only when using standby nodes. This includes recovery (when using standby nodes) of hierarchical storage management (HSM) products using the data management application programming interface (DMAPI).
A standby node is a metadata server-capable administration node that is configured as a potential metadata server for a given filesystem, but does not currently run any applications that will use that filesystem. To use recovery, you must not run any applications on any of the potential metadata servers for a given filesystem; after the active metadata server has been chosen by the system, you can then run applications that use the filesystem on the active metadata server and client-only nodes.
Relocation and recovery are fully implemented, but the number of associated problems prevents full support of these features in the current release. Although data integrity is not compromised, cluster node panics or hangs are likely to occur. Relocation and recovery will be fully supported in a future release when these issues are resolved.
For information on CXFS, see SGI InfiniteStorage CXFS Administration Guide.

Introduced in IRIX 6.5.17f:

The IRIX 6.5.17f release includes the XVM Manager GUI. The XVM Manager GUI provides access to the tasks that help you set up and administer XVM logical volumes and provides icons representing states and structure of the XVM volume elements.
With the XVM Manager GUI, you can perform the following tasks:
- Administer XVM logical volumes by means of a web browser, such as Netscape or Internet Explorer.
- Drag and drop XVM volume elements to create local and cluster volume topologies.
- Drag and drop disks to label them or give them away.
- See volume element and filesystem status changes instantly, reflected in color-coded icons.
- Click buttons to create volume elements quickly.
For information on the XVM Manager GUI, see XVM Volume Manager Administrator's Guide.
Use of the XVM snapshot features requires a FLEXlm license.
IRIX 6.5.17f includes support for the use of local XVM volumes as FailSafe resources. This requires FailSafe version 2.1.3. XVM volumes used in conjunction with CXFS should not be added as FailSafe resources. For information on configuring FailSafe resources, see the IRIS FailSafe Version 2 Administrator's Guide, 007-3901-006.

Introduced in IRIX 6.5.16f:

For the IRIX 6.5.16f release, the -extend option was added to the XVM show command. Specifying this option will display additional information about physvols, slices, stripes and foreign disks than the show command alone. The XVM Volume Manager Administrator's Guide and the XVM help screens have been updated with examples that use this option.
For IRIX 6.5.16f, CXFS features include the following:
- Support for multiple operating system (multiOS) clients, such as Solaris nodes and Windows NT nodes. The CXFS GUI and cmgr(1M) command now allow you to specify the operating system for a given node.
- I/O fencing, which allows a problem node to be isolated from the storage area network (SAN) so that it cannot corrupt data in the shared CXFS filesystem; this is required for Solaris nodes and Windows NT nodes. A Brocade switch is required to support I/O fencing.
- Support for a two-node CXFS cluster running with FailSafe and an L1 controller on Origin 300 and Origin 3200 systems.
See the SGI InfiniteStorage CXFS Administration Guide for more information.
The IRIX 6.5.16f release added the joblimitsign group of kernel tunables that can be used to specify that specific job limit resource accumulation and enforcement should be ignored by the kernel. Setting the kernel tunable value to 1 indicates the specific limit should be ignored. Setting the value to 0 will re-enable the limit for newly created jobs.
The following kernel tunable parameters have been added:
- jlimit_cpu_ign parameter
  The jlimit_cpu_ign parameter specifies that the accumulation and enforcement of CPU time limits for jobs should be ignored.
- jlimit_data_ign parameter
  The jlimit_data_ign parameter specifies that the accumulation and enforcement of data memory limits for jobs should be ignored.
- jlimit_nofile_ign parameter
  The jlimit_nofile_ign parameter specifies that the accumulation and enforcement of limits for the number of open files in jobs should be ignored.
- jlimit_numproc_ign parameter
  The jlimit_numproc_ign parameter specifies that the accumulation and enforcement of limits for the number of processes in jobs should be ignored.
- jlimit_pmem_ign parameter
  The jlimit_pmem_ign parameter specifies that the accumulation and enforcement of physical memory limits for jobs should be ignored.
- jlimit_pthread_ign parameter
  The jlimit_pthread_ign parameter specifies that the accumulation and enforcement of limits for the number of pthreads should be ignored.
- jlimit_rss_ign parameter
  The jlimit_rss_ign parameter specifies that the accumulation and enforcement of resident set size (RSS) memory limits for jobs should be ignored.
- jlimit_vmem_ign parameter
  The jlimit_vmem_ign parameter specifies that the accumulation and enforcement of virtual memory limits for jobs should be ignored.
For more information on kernel tunable parameters, see the setjusage(2) entry in Appendix A in IRIX Admin: Resource Administration.
In IRIX 6.5.16f, the new setjusage system call is used to update resource usage for jobs in the kernel. The system call can only be used to update usage information if the limit accumulation and enforcement for the specified resource is being ignored. This function can be used by sites to implement a site-specific solution for resource accumulation and enforcement. Using this system call allows the various job limit status commands to display usage values as reported from the site-specific implementation. For more information, see the setjusage(2) man page and the setjusage(2) entry in Appendix A in IRIX Admin: Resource Administration.
The IRIX 6.5.16f release removes the ACCT_FS parameter in the /etc/csa.conf file. The MIN_BLKS parameter now determines the minimum number of free 1K blocks needed on the file system on which the /var/adm/acct directory resides. The default is 2000. To ensure that the MIN_BLKS variable has been set correctly, check the value in the /etc/csa.conf configuration file.
For more information, see Chapter 5, "Comprehensive System Accounting", in IRIX Admin: Resource Administration.

Introduced in IRIX 6.5.15f:

As of the IRIX 6.5.15f release, the default naming convention for subvolumes in the /dev/lxvm/ and /dev/cxvm directories is volname, subvolume.
Older releases of XVM created a directory entry for a subvolume of the form volname_subvolname. This convention can yield potential problem. For example, since vol1_data is a legal name for a volume it is impossible to determine whether /dev/lxvm/vol1_data refers to the data subvolume of the volume vol1 or to a volume named vol1_data. The volname_subvolname form of subvolume directory entries is still supported in IRIX 6.5.15f and later, but its use is not recommended.

For information on XVM device directories and pathnames, see the XVM Volume Manager Administrator's Guide.
As of the IRIX 6.5.15f release of IRIX, you can implement disk quotas on XFS filesystems according to group ID. Previous releases of IRIX supported implementing quotas according to user and project ID. Project and group accounting are mutually exclusive. This feature is on-disk compatible with Linux-XFS group accounting, where this feature is already active. For information on administering XFS quotas, see IRIX Admin: Disks and Filesystems.
Caution: Group quotas are supported in the feature stream only. If you implement group quotas on a disk and, subsequently, mount that disk with the pquota mount option on a machine running the maintenance stream or an earlier release of the feature stream on which group quotas are not supported, the quota accounting could be corrupted.
IRIX 6.5.15f provided the following new features for CXFS.
- Support has been added for clients of other operating systems such as Solaris as defined in CXFS Client Administration Guide. These clients are released asynchronously from the IRIX release. This support requires IRIX 6.5.15f or later plus appropriate patches. For more information, contact your SGI support contact.
- Default scripts are now provided in the /var/cluster/clconfd-scripts directory to permit NFS-exporting of CXFS filesystems listed in /etc/exports.
- Changes have been made to the rotatelogs script syntax. The root crontab file now has an entry to run the rotatelogs script weekly. If you run the script twice in one day, it will append the current log file

Introduced in IRIX 6.5.14f:

The CXFS GUI was enhanced in the IRIX 6.5.14f release as follows:
- CXFS Manager and CXFS Cluster View windows are now combined into one window called CXFS Manager.
- Tasks can now be launched by clicking the right mouse button over the tree-view area, or by selecting Tasks on the menu bar.
- Command line interfaces (CLIs) that the GUI runs can be viewed from a new File > Show SALog menu item.
- You can now partially mount filesystems on just a subset of nodes, using the Define Filesystem and Modify Filesystem tasks.
- A new Find text field helps you find items within the displayed tree-view area.
- Filesystem status and cluster status update faster.
For more information, see the SGI InfiniteStorage CXFS Administration Guide.

Introduced in IRIX 6.5.13f:

With IRIX 6.5.13f, the structure of the CXFS filesystem configuration was changed. CXFS filesystems can now be defined, modified, managed and deleted independently of each other, and of the cluster definition. (Previously, the CXFS filesystems were defined as attributes to the cluster definition.) To accommodate clusters mixing nodes running IRIX 6.5.12f and IRIX 6.5.13f, backwards compatibility is enforced by default in IRIX 6.5.13f. For more information, see the SGI InfiniteStorage CXFS Administration Guide.
The XVM Volume Manager can be used when layered with the CXFS filesystem. The XVM Volume Manager can also be used as a standalone volume manager; this requires that you be running the IRIX 6.5.13f release leg of the IRIX operating system. The IRIX 6.5.13m leg does not support XVM as a standalone volume manager; this support will be added in a later release. For information on CXFS filesystems, see SGI InfiniteStorage CXFS Administration Guide.
The IRIX 6.5.13f release added support for the use of mirrors in XVM logical volumes. The mirroring feature of XVM requires the XFS Volume Plexing software option. Customers running CXFS and who want to run mirrors will need to purchase this license. XLV customers with plexing licenses can upgrade to XVM without having to acquire a new license.

Introduced in IRIX 6.5.12f:

Supports the labeling of disks as XVM system disks in the XVM Volume Manager. This lets you create XVM logical volumes that include the partitions of a system disk. The following XVM system disk features are supported:
- Root partitions can be mirrored
- There can be multiple root partitions on a system disk
- You can include usr and swap partitions in any XVM logical volume configuration, including mirrors, concats, and stripes
- A system disk can include slices that are not part of a root, usr, or swap partition
You can now convert existing system disks to XVM system disks, and then use their partitions as part of an XVM logical volume. After you have converted an existing system disk to an XVM disk, you can convert the disk back to its original state by unlabeling the disk with the XVM unlabel command. For information on XVM system disks, see the XVM Volume Manager Administrator's Guide.

Introduced in IRIX 6.5.10f:

XVM installed with CXFS is now qualified on IP35 (Origin 3000) systems in addition to the existing qualification on the IP27 (Origin 200, Origin 2000, and Onyx2) and IP30 (Octane) systems.

Introduced in IRIX 6.5.9f:

CXFS supports the use of hierarchical storage management (HSM) products through the data management application programming interface (DMAPI). An example of an HSM product is the SGI DMF product.
Support for the Scheduled Transfer Protocol (STP). STP is a lightweight network protocol that is compliant with the ANSI Standard Revision 3.1 protocol suite that is designed to support extremely high performance data movement. STP uses Direct Memory Access (DMA) to read and write data into user space from a network interface. This lets high bandwidth devices, such as Gigabyte System Network (GSN) and Gigabit Ethernet (GigE), perform at network speeds with minimum interrupt overhead. For more information, see the stp(7P) man page or http://www.hippi.org.) This STP feature was initially added in IRIX 6.5.9. In IRIX 6.5.6, STP was initially added to the IRIX feature stream with minimal functionality.
Support for disk quotas that can now be set by project ID. Disk quotas let you limit the amount of space a user or project can occupy and the number of files (inodes) that each user or project can own. You can implement hard or soft limits; hard limits are enforced by the system and soft limits only remind the user to decrease disk usage.
For more information on disk quotas and their administration, see IRIX Admin: Disks and Filesystems, which now includes information about project quota administration. For more information on project IDs, see IRIX Admin: Backup, Security, and Accounting. For more information on the administration of disk quotas by project, see the edquota(1M), find(1M), quota(1M), repquota(1M), and fstab(4) man pages.
Support for the waitjob feature, which includes the new functions setwaitjobpid( ) and waitjob( ). These functions let the batch schedulers query job information following job termination. When a batch scheduler launches a job, it calls setwaitjobpid( ) to tell the new job what pid is waiting for information upon termination. When the job terminates, it remains as a zombie until either the batch scheduler calls waitjob( ) to retrieve the job's termination information or the waiting pid no longer exists. The information returned includes the job start time, usage information, and reason for termination.
For more information, see IRIX Admin: Resource Administration and the waitjob(1M) and setwaitjobpid(1M) man pages.

Introduced in IRIX 6.5.8f:

Support for Comprehensive System Accounting (CSA). CSA is a set of user and administrative C programs and shell scripts that provide methods to collect per-process resource usage data, monitor disk usage, and charge fees to specific login accounts. CSA uses this per-process accounting information and combines it by job identifier within the system boot uptime periods. CSA provides the following features that are not available with any other IRIX accounting package:
- Per-job accounting
- Daemon accounting (tape and Network Queuing System (NQS))
- Flexible accounting periods (daily and periodic accounting reports can be generated as often as desired and not restricted to once per day or once per month)
- Flexible system billing units (SBUs)
- User exits for site specific customization of daily and periodic accounting
- Configurable parameters within the /etc/csa.conf file
- User job accounting (ja command)
For more information, see IRIX Admin: Resource Administration and the csa(1M) man page.

Introduced in IRIX 6.5.7f:

Support for the CXFS product, which provides a cluster file system that allows file sharing between machines. CXFS includes the following capabilities:
- High resiliency and availability
- Reduced storage costs
- Scalable high performance
The 6.5.7f release contains metadata server recovery. See the SGI InfiniteStorage CXFS Administration Guide for the administrative shutdown procedures and additional troubleshooting information. The CXFS feature was initially added in IRIX 6.5.6f.
Support for job limits. You can use this feature if you want to prevent individual users from exceeding specified usage limits; this can improve system throughput and utilization by restricting how much of the machine each user can access. For more information, see IRIX Admin: Resource Administration and the jstat(1), jlimit(1), genlimits(1M), and showlimits(1) man pages.

Introduced in IRIX 6.5.2f:

Motif 2.1/ViewKit 2.1
IRIX Oplock Support
Support for Non EUC encoding and locales (sjis/big5/gbk/utf8)

Maintenance and Feature Stream

Introduced in IRIX 6.5.23:

IRIX 6.5.23 included the following new features for CXFS:
- Support for both relocation and recovery to a standby (idle) server. Relocation is disabled by default.
- Support for a cluster of up to 64 nodes.
- The ability to define a reset method for a given node to one of the following:
  - Power cycle, to turn power off and on
  - Reset, to simulate the pressing of the reset button on the front of the machine
  - NMI, to perform a nonmaskable interrupt
  You can define this method using either the cmgr command or the GUI. You can manually perform a powercycle or an NMI with the cmgr command.
For information on these features, see CXFS Administration Guide for SGI InfiniteStorage.

The IRIX 6.5.23 release supports SGI Infinite Network Bandwidth. Infinite Network Bandwidth aggregates a number of physical network interfaces into a single virtual interface that is able to spread data evenly across all the physical interfaces in a stripe set. This allows multiple packets to be sent and received in parallel. This greatly increases the available bandwidth to the virtual interface. For information on Infinite Network Bandwidth, see IRIX Admin: Networking and Mail.
The IRIX 6.5.23 release supports the dual-port Gigabit Ethernet board. It is available in two formats: the dual-port Fiber-Optic Gigabit Ethernet board and the dual-port Copper Gigabit Ethernet board. For descriptions of these boards, information on how to connect the boards to an Ethernet network, and an explanation of how to operate the boards, see the SGI IRIS Release 2 Dual-Port Gigabit Ethernet Board User's Guide.

IRIX 6.5.23 provides support for POSIX 1003.1j pthread barriers and spinlocks. For information, see the pthread_barrier_wait(3P) and pthread_spin_lock(3P) man pages.

In IRIX 6.5.23, the rtmon-client and rtmond daemon support IPv6. For information, see the rtmon-client(1) and rtmond(1) man pages.

For the IRIX 6.5.23 release, the Embedded Support Partner (ESP) has been upgraded to version 3.0, the same version of Embedded Support Partner deployed on SGI's Altix systems. The ESP2.0 event manager component has been decoupled and generalized to allow for more flexible system group management. An ESP3.0 System Group Manager (SGM) supports both ESP2.0 and ESP3.0 clients (Linux or MIPS). All existing ESP2.0 data will automatically be converted for use by ESP3.0. In addition, all existing ESP2.0 reports are supported as is the auto-logging of calls to SGI for supported customers. For further information see the Embedded Support Partner User Guide.

Introduced in IRIX 6.5.22:

As of IRIX 6.5.22, support for the following features is provided in both the feature stream and the maintenance stream. In previous releases, these features were supported in the feature stream only:
- The XVM logical volume manager
- CXFS
- The SJIS feature of IRIX Language Support, supporting Shift JIS, Traditional Chinese BIG5, and Simplified Chinese GBK locales.

The graphical user interfaces (GUIs) for CXFS and XVM contained in IRIX 6.5.22 and later no longer support the localized Japanese GUI and the Japanese resource files do not ship with "WorldView Japanese 6.5 For IRIX 6.5.22 and above". If you are upgrading to CXFS or XVM on a system running IRIX 6.5.22 or later versions and have previously installed the Japanese resource files for these packages, you should remove them. To remove the Japanese resource files, run the following commands as root:
# versions remove WorldView_japanese.sw.euc_sysadm_cxfs
# versions remove WorldView_japanese.sw.sjis_sysadm_cxfs
# versions remove WorldView_japanese.sw.euc_sysadm_xvm
# versions remove WorldView_japanese.sw.sjis_sysadm_xvm
# versions remove WorldView_japanese.sw.euc_sysadm_cluster
# versions remove WorldView_japanese.sw.sjis_sysadm_cluster
# versions remove WorldView_japanese.sw.euc_sysadm_base
# versions remove WorldView_japanese.sw.sjis_sysadm_base

In IRIX 6.5.22, the mkfs command supports a new version=ci suboption for the -n (naming) option. Specifying this option enables a version 2 filesystem directory with case-insensitive filenames. Filenames will be stored in directories as they were created, but all file or directory name searches will be case-insensitive. This feature is normally used only when the filesystem will be used by Windows CXFS clients.
Note that you will be able to mount filesystems created with this option only when running IRIX releases 6.5.22 and later. Attempting to mount the filesystem when running an earlier release produces an error message of "Wrong filesystem type: xfs".
For information on the mkfs command, see the mkfs_xfs(1M) man page.

Trusted IRIX support and Extended Attribute support (using UDF streams) was added to the UDF filesystem for IRIX 6.5.22.

In IRIX 6.5.22, the operation of the REPLACE action keyword of the cpr command has been enhanced.
Under certain constraints, REPLACE actions may invoke SUBSTITUTE actions for files that have been modified or deleted, or a MERGE action for all other files.
If a SUBSTITUTE action is performed, a notice specifying the location of the substituted file is displayed. It is the responsibility of the user to pick up any output file thus substituted. Applications that reopen a substituted file by its original name may not operate as expected.
Checkpoint/Restart users are encouraged to review the information on this behavior change detailed in the IRIX Checkpoint and Restart Operation Guide.

IRIX 6.5.22 includes support for Pluggable Authentication Modules (PAM). PAM provides a general purpose interface for customer-definable authentication. Implementation of PAM is off by default. For information on PAM, see IRIX Admin: Backup, Security, and Accounting.

The IRIX 6.5.22 release includes musicplayer, a skinnable desktop music player that plays sound files using sgi audio hardware. The musicplayer application handles multiple files in a single session. For information, see the musicplayer(1) man page and the online help provided in the Help menu of the application.

In IRIX 6.5.22, a driver can obtain information about the PCI bus in which its device is installed. (The only information available about PCI buses on the other side of a PCI-to-PCI bridge is whether multi-master capability is supported.) PCI bus information is returned by the pciio_businfo_get() function as a pointer to a bus information structure pciio_businfo_s. For information about interrogating a PCI bus, see the IRIX Device Driver Programmer's Guide.

The IRIX 6.5.22 release includes the following improvements to NFS
- Changes have been made to the operation of the buffer cache during NFS operation. These updates keep I/O performance from collapsing under heavy load and improve the efficiency of I/O in general.
- A new mode has been added to IRIX's kernel NFS service where the number of NFS server daemons grows and shrinks in response to NFS load. Previously on IRIX this was a fixed number that the system administrator had to choose, and both the default number and the recommended tuning procedure ensured inadequate NFS performance for many workloads. IRIX now requires less tuning and will perform better out of the box.
  For information on this mode, see the section on DYNAMIC NFS DAEMONS in the nfsd(1M) man page.
- A new -d option has been added to the nfsstat command that will display statistics about individual NFS daemons. For information on this option, see the nfsstat(1M) man page.
- NFS now provides an optional "async" mode to improve write performance. This mode is set with the async option of the exportfs command. By allowing an administrator to switch from synchronous write/commit cycles to performing the same operations asynchronously, NFS writes can finish up-to 10 times faster on the client and server can perform writes in the way which can optimize backend filesystem IO pattern. This option is recommended only for heavy synchronous write loads. For further information, see the exportfs(1M) man page.
- An "offline" option to the exportfs command has been added for use with Failsafe operations. Historically Failsafe relied on brute-force approach to stop NFS-related activity by killing NFS daemons. With the "offline" option a selected subset of filesystem can be moved offline while NFS server can continue to serve requests to other filesystems. For information on this option, see the exportfs(1M) man page.

Network time protocol (NTP) is a newly supported component as of the IRIX 6.5.22 release. For more information see "Setting up Time Synchronization Service" in IRIX Admin: Networking and Mail.

The IRIX 6.5.22 release supports BIND version 9.2.2. BIND version 9 is a major rewrite of nearly all aspects of the underlying BIND architecture. For more information on BIND version 9, see IRIX Admin: Networking and Mail. Detailed information is available at: http://www.isc.org. Follow the link to BIND documentation.

Introduced in IRIX 6.5.21:

In an SGI Origin 3900 system, a Cx-brick contains node boards without CPU packages or cache that are referred to as a memory-only nodes. The Cx-brick is a "super" CPU brick. It contains multiple node cards. One of those node cards must be a CPU node, but any of the other nodes can be memory-only nodes. Memory-only nodes, sometimes called headless nodes, allow you to expand the memory capabilities of your system without the cost or overhead of adding unnecessary additional processors.

In IRIX 6.5.21, the new keyword directives for use in the cpuset configuration file (there are equivalent structures or flags for the cpuset API) to support memory-only nodes are as follows:

POLICY_SHARE_WARN
POLICY_SHARE_FAIL
NODE nodeid or nodeids
MEM nodeid or nodeids
MEMORY_SIZE_ADVISORY size
MEMORY_SIZE_MANDATORY size
CPU_COUNT_ADVISORY count
CPU_COUNT_MANDATORY count

For a description of these new keywords see the cpuset(4) man page and IRIX Admin: Resource Administration.

Boot cpusets are used to constrain regular system activities to a subset of the available CPUs. In IRIX 6.5.21, kernel threads not forced to run on specific CPUs run within the boot cpuset if one exists. Boot cpusets are used to constrain regular system activities to a subset of the available CPUs.

In IRIX 6.5.21, the tcp_wrappers package is available in the eoe.sw.base IRIX subsystem. It consists of the following components:

A library in /usr/lib/libwrap.so
A header file in /usr/include/tcpd.h
A suite of programs to verify tcp_wrappers operation: tcpdchk, tcpdmatch, and try-from

In IRIX 6.5.21, inetd(1m) is built with tcp_wrappers by default. See the inetd(1M) man page for details.

For information on using the tcp_wrappers package, see the IRIX Network Programming Guide.

The IRIX 6.5.21 release provides a new PLACEMENT policy keyword for checkpoint and restart processes. PLACEMENT offers two action keywords, STRICT and FLEXIBLE. The STRICT action keyword restores the memory of process(es) according to the placement policies saved at the time of checkpoint. The FLEXIBLE action keyword attempts to place process memory according to a basic memory placement algorithm (TOPOLOGY_FREE) if and only if process memory placement fails when adhering to the checkpointed placement policies; this is the default action. For more information on this new PLACEMENT policy, see the cpr(1) man page and the IRIX Checkpoint and Restart Operation Guide.
IRIX 6.5.21 includes support for the M-Audio Revolution PCI audio card on Octane and Octane2 systems.
The sysdump command, first added in IRIX 6.5.19, has been enhanced to generate level 1 system crash dump files of a running system. The sysdump command is used by system administrators to generate a crash dump file of the operating system without the need to reboot the system. The crash dump file can be used to diagnose system problems. For information, see the sysdump(1M) man page.
IRIX 6.5.21 provides support for the thread and system nonpreemption pthread mutex protocols that let real-time pthreads avoid being preempted while in critical sections. Real-time developers would use this feature when the priority inheritance and priority ceiling mutexes incur too much overhead. For information, see the pthread_mutexattr_setprotocol(3P) man page.
IRIX 6.5.21 includes OpenLDAP version 2.1.17. The previous release of OpenLDAP on IRIX was split into an openldap and an openldap_dev package. This release combines both packages into a single openldap package that includes all libraries, headers and binaries normally included in the OpenLDAP distribution. For information on OpenLDAP, see http://www.openldap.org/.
IRIX 6.5.21 includes OpenSSH version 3.6.1p2. For information on OpenSSH, see http://www.openssh.com/.
IRIX 6.5.21 includes OpenSSL version 0.9.7b. The previous release of OpenSSL on IRIX only included selected libraries. This release includes all libraries, headers and binaries normally included in the OpenSSL distribution. For information on OpenSSL, see http://www.openssl.org/.
IRIX 6.5.21 includes support for USB tablets.
In the IRIX 6.5.21 release, the NFS Access control mechanism has been updated to support new access control list elements such as IP netmasks, domain name suffixes and explicit exclusion of a host or group of hosts. For information see the exports(4) man page.
NFS Access control checks are now performed by rpc.mountd for both MOUNT and NFS protocols.
With the 6.5.21 release, a user must have the same or a subset of the Mandatory Integrity (MINT) divisions of an object in his or her label and the integrity divisions of the user must be the same or a subset of the integrity divisions of the object. For information, see the Trusted IRIX/CMW Security Administration Guide.
With this release, the integrity divisions of the user must be the same or a subset of the integrity divisions of the file. For information, see the Trusted IRIX/CMW Security Features User's Guide.

Introduced in IRIX 6.5.20:

For the IRIX 6.5.20 release, Sysadm Base 3.0 ports the Sysadm Base 2.0 software from Java1 (version 1.1.8) to Java2 (version 1.4.1) which is the latest Java version supported by SGI. Sysadm Base 3.0 supports SGI's IRIX software for remote cluster and storage administration. The CXFS, FailSafe, and XVM Manager GUIs depend on Sysadm Base.
The use of Java2 simplifies the Java installation and co-operation with third-party GUIs. This also enhances the ability to run the GUIs through a web browser. For example, for the CXFS GUI, you can open http://server/CXFSManager/.
IRIX 6.5.20 integrates MP3 audio decoding into the digital medial libraries and all associated dmedia tools. For information, see the soundplayer(1) man page or the Digital Media Programmers Guide.
IRIX 6.5.20 supports the Huffman YUV (HuffYUV) video codec, which allows lossless real-time compression of 4:2:2 video in the range of 2:1 to 3:1. Note that since it is software-based, we do not guarantee real-time compression. For information, see the movieplayer(1), dmconvert(1), and makemovie(1) man pages.
IRIX 6.5.20 adds support for the Griffin iMic USB audio interface.
IRIX 6.5.20 adds support for the M-Audio Revolution PCI audio card.
OpenGL Shader is now shipped with IRIX. OpenGL Shader is a powerful multi-platform appearance-modeling tool that provides incredible realism effects through an easy and powerful development toolkit. For information see the release notes installed under /usr/relnotes/shader_eoe and the ISL shading language specification installed under /usr/share/shader/doc/user/islspec.html.
Universal Disk Format (UDF) is the filesystem used on DVDs. The UDF specifications are produced by OSTA, and are based on the ECMA-167 specification. A read-only implementation of UDF was added to IRIX 6.5.18, and a write-capable version was added for IRIX 6.5.20.
For the IRIX 6.5.20 release, support for Motif 2.1 and ViewKit 2.1 development has been added to the Maintenance stream.
IRIX 6.5.20 includes libraries and utility programs from MIT kerberos V version 1.2.7. The libraries included are: libcom_err.so, libdes425.so, libgssapi_krb5.so, libk5crypto.so, and libkrb5.so. The following utility programs are included: kdestroy, kinit, klist, kpasswd, and kvno. For information on kerberos, see http://web.mit.edu/kerberos/www/.
IRIX 6.5.20 includes OpenLDAP version 2.1.12 with support for TLS/SSL and Kerberos authentication. This includes the complete suite of programs and header files necessary to implement an LDAP server and client applications. For information on OpenLDAP, see http://www.openldap.org/.
The Job Limits and Comprehensive System Accounting packages, long available in the IRIX feature stream, have been added to the maintenance stream. These features are available in the optionally installable packages eoe.sw.jlimits and eoe.sw.csa.
For IRIX 6.5.20 the mod_ssl package has been added to the sgi_apache web servers. The mod_ssl package adds secure http (https or TLS) support to apache, using openssl to do the encryption. Note that to use secure connections you must generate a certificate for your host. See the sgi_apache release notes for details.
The IRIX 6.5.20 release adds support for Trusted IRIX attributes to checkpoint and restart processes (CPR). If enabled, capabilities, mandatory access control (MAC) labels, and access control lists (ACLs) are saved at the time of checkpoint and restored upon restart. Capabilities are saved and restored for processes and files. MAC labels are saved and restored for processes, files, pipes, named pipes, and System V shared memory segments. ACLs are saved and restored for files and named pipes. For more information on these attributes, see "Using CPR in Trusted IRIX" in the IRIX Checkpoint and Restart Operation Guide and the capabilities(4), DOMINANCE(5) and acl(4) man pages.
The IRIX 6.5.20 release adds information about set-capabilities (SCAP) programs in a Trusted IRIX environment to the "Capability Assignment" section of Trusted IRIX/CMW Security Administration Guide as follows:
Like set-user-ID (SUID) and set-group-ID (SGID) programs, programs assigned capabilities (set-capabilities (SCAP) programs) are handled differently. A user cannot use the process activity reporter par system utility program on a SCAP process or trace a SCAP process unless the user has the CAP_PROC_MGT capability. See the par(1) and exec(2) man pagase for more details.
Similarly, certain environments variables are not respected when dealing with SCAP programs. These include _RLD*_LIST and LD_LIBRARY*_PATH environment variables of the runtime linker rld command, the IFL_DATABASE environment variable of the Image Format Library ifl command (see rld(1) and ifl(1)) and the NLSPATH environment variable of the open/close a message catalogue catopen routine that allows user control of message formatting (see catopen(3C)).
IRIX 6.5.20 adds information to IRIX Admin: Resource Administration on using the XThread Control Interface (XTCI) with cpusets as follows:
Kernel system threads and interrupt threads can be confined to the boot cpuset by using the XThread Control Interface (XTCI), which is documented in the realtime(5) man page and the REACT Real-Time Programmer's Guide.

Introduced in IRIX 6.5.19:

IRIX 6.5.19 provides a Pseudo Random Number Generator, accessible through the special files /dev/random, and /dev/urandom. These files support the standard file interface operations. The PRNG is implemented in the kernel. For further information, see the random(7) man page.

In IRIX 6.5.19, the rdrtc() function was added to libc. This function provides a simplified interface to read the system's raw real-time clock value. This feature is similar to those in other operating systems that read the cycle counter. For information, see the rdrtc(3c) man page.

IRIX 6.5.19 includes OpenSSH version 3.4p1. This has been patched for TRIX support and SOCKS support and uses the OpenSSL libraries.

For IRIX 6.5.19, a bug was fixed that allowed processors isolated and made non-preemptive with mpadmin() or sysmp() to become unisolated while still non-preemptive. This has been changed to force the processor to become preemptive before it can become unisolated. For information, see the mpadmin(1) and sysmp(2) man pages.

IRIX 6.5.19 supports Internet Protocol Version 6 (IPv6). Internet Protocol Version 6 (IPv6) is the next generation Internet protocol, designed eventually to replace the current IPv4. IPv6 is expected to grow in usage gradually over many years and will coexist and interoperate with IPv4 for the foreseeable future.

IPv4 uses a 32-bit address scheme to represent a unique Internet address while IPv6 uses a 128-bit addressing scheme. Because IPv6 has four times the number of bits to represent addresses, it provides several billion times the address space of IPv4 and adds an almost unlimited number of available IP addresses. This resolves a projected future shortage of IPv4 addresses as more and more devices are added to the Internet.

To ease the transition from IPv4 based networks to IPv6, IRIX supports a dual-stack protocol implementation that supports both IPv4 and IPv6 protocols on the same system. The IPv6 basic socket API is supported and allows network programs to use either protocol. The IPv6 API software interface communicates transparently with both IPv4 and IPv6 nodes. It automatically chooses the right protocol to communicate with any particular node. It has an encapsulation mechanism called tunneling that allows IPv6 packets to operate over IPv4 networks. The IPv6 protocol allows networking applications to operate transparently in both environments.

For more information, see the IRIX Network Programming Guide and IRIX Admin: Networking and Mail.

The new gigabit ethernet driver (device tgx) now dynamically adjusts the cards parameters to maintain good performance across very dynamic workloads. Manual setting of this parameter is no longer needed.

IRIX 6.5.19 includes 64-bit versions of libaudiofile and libcdaudio. For information on these libraries, see the afIntro(3dm) and CDintro(3dm) man pages.

IRIX 6.5.19 supports sendmail version 8.12.5, which provides the following features:

Simple Mail Transfer Protocol (SMTP)
Performance improvements including multiple queues, memory-buffered pseudo-files, and more control over resolver timeouts.
Support for "message submission agent", as defined by RFC 2476.
Changes to support running sendmail with group-id privileges. sendmail no longer runs with set-uid-root privileges.
Ability to connect to servers running on named sockets.
Changes to support IPv6.
Improved support for virtual hosting.
Improved anti-spam control features.
Several new map classes, including ph, arith, and macro.

For more information on sendmail, see IRIX Admin: Networking and Mail.

For security reasons, sendmail is no longer implemented as a setuid-root program. Rather, it is implemented as a setgid-sgismmsp program. The sendmail functionality is now split between the Mail Transfer Agent (MTA) and Mail Submission Agent (MSA) programs and requires new account and group categories both named sgismmsp.
Trusted IRIX/CMW system relies on a number of administrative data files to provide crucial information for the system.
This release adds a new /etc/mail/submit.cf configuration file for the mail submission program which is used to submit emails as invoked by programs (or users).
For more information, see the Trusted IRIX Security Administration Guide and IRIX Admin: Networking and Mail.

Introduced in IRIX 6.5.18:

The IRIX 6.5.18 release includes read-only support for the UDF filesystem format typically used for DVDs and packet-written CD-RWs. IRIX support for UDF filesystems does not, however, include support for playing DVD movies. DVDs will be automatically mounted by mediad in the same way that CD-ROMs are automatically mounted. For further information on mounting UDF filesystems, see IRIX Admin: Peripheral Devices.
Note: Support for UDF filesystems requires that you install eoe.sw.udf.
QLFC has been enhanced to improve its output message format for messages logged to the console and SYSLOG. The name of the driver as it appears in messages has been changed from "QL" to "QLFC". The syntax of the messages has been modified to include the fabric port number in the message, in a form similar to the manner in which fabric devices are named.
For example, where the old driver would output this message:
ql11d(0x200400a0b80cd1ab): target has returned.
the new driver will output this message:
qlfc11: 200400a0b80cd1ab/c11p2: target has returned.
In IRIX 6.5.18, the /etc/shells file has been added to provide system administrators with the ability to define appropriate shells for users. The implementation of this feature includes the following ramifications:
- A user's shell, as defined in /etc/passwd or an NIS map, must be listed in /etc/shells for the user to change a password with yppasswd or ypchpass.
- A user's shell, as defined in /etc/passwd or an NIS map, must be listed in /etc/shells for sendmail to deliver a user's mail if the user's mail is piped to a process (such as procmail or vacation).
Users are able to log in and use the system interactively, regardless of whether the shell is listed in /etc/shells. For more information see the shells(4) man page.
For the IRIX 6.5.18 release, the hinv command with the -v option displays the PCI/PCI-X bus speed of QLogic fibrechannel adapters. The hinv -t scsictlr command displays the SCSI/fibrechannel adapters.
Beginning with IRIX 6.5.18, a user is able to keep the interrupt and processing load generated by interval timers away from specific CPUs. This feature may reduce latency and jitter for real-time applications. For more information see the sysmp(2) and mpadmin(1) man pages.
The reboot_on_panic parameter, when set to 1, specifies that the system should automatically reboot after a kernel panic. This is particularly useful for servers or other systems which frequently go unattended or are used remotely, where it may not be convenient to physically reset the system. The default for SGI servers and large graphical systems is to reboot after a kernel panic.
It is important to note that the rebound variable, an environment variable set in the PROM monitor for most processors, is always checked before the reboot_on_panic parameter and can override it. If the reboot_on_panic parameter is set to 0 and the rebound value is set to y, the reboot_on_panic parameter in effect becomes 1 and your system will automatically reboot.
For more information, see IRIX Admin: System Configuration and Operation.
Job limit values (rlim_t) are 64-bit in both n32 and n64 binaries. Consequently, n32 binaries can set 64-bit limits. o32 binaries cannot set 64-bit limits because rlim_t is 32-bits in o32 binaries. IRIX supports three Application Binary Interfaces (ABIs): o32, n64, and n32 (for more information on ABIs, see the abi(5) man page). IRIX Admin: Resource Administration, IRIX Admin: System Configuration and Operation, and the setjlimit(2) man page have been updated with this information.
At checkpoint time and at restart time, registered functions are called in the same order as the first-in-first-out order of their registration with atcheckpoint() or atrestart(), respectively. This is an important consideration for applications that need to register multiple callback handlers for checkpoint or restart events.
Use of atcheckpoint() and atrestart() now ensures that registered signal handlers are invoked only when a checkpoint or restart of the application is actually in progress (as opposed to the user sending the signals directly via a function such as sigsend()).
The Falls screen saver is a new choice that can be selected from the IRIX screen saver control panel. It is an OpenGL depiction of a waterfall.

Introduced in IRIX 6.5.17:

With IRIX 6.5.17, the underlying documentation tools and books have undergone a major upgrade. These processes now allow for SGML or XML documents to be published directly into HTML (our delivery format). These same tools are available to you as part of the "SGI Book Building Tools" product; formerly the "IRIS InSight Professional Publisher".
For viewing documentation on the IRIX Interactive Desktop, the following changes have been made: InfoSearch (the primary online documentation viewer) has been revamped to support the new document format, SGIHelp (the IRIX Desktop Help system) has undergone minor changes, and the Dynaweb product is no longer shipped (or required). In addition, the IRIS InSight Viewer (insight) now exists solely as an intermediate process that launches your standard desktop web browser to access InfoSearch. Online books can also be viewed using your standard desktop web browser by opening the (local) file: /usr/share/Insight/library/SGI_bookshelves/index.html
Our goal is to deliver all online books to you in this new format. There are circumstances whereby some books may still exist on your local system in the "old format". Examples would include some of the SGI Developer documentation: the MIPSpro compiler books and the ProDev WorkShop books fall into this category (books that require conversion). The online documentation tools will report a warning when encountering books in the "old format" that require conversion.
A conversion process is provided (the existing insightAdmin command). Various options for performing the conversion are available through this tool. It is important to note that the conversion only needs to be done once, unless additional products are installed that still contain books in the "old format". Be advised that this process can be time consuming. Total time is based on the size and number of books that need to be converted, and the availability of system resources. On average, 1-3 minutes per book on an older desktop-class machine (R5000 O2) can be expected. For that reason, a system administrator may wish to perform this operation at an off-peak time.
For further details, see the insight and infosearch release notes, and the related man pages (insightAdmin, insight, sgihelp, infosearch). Virtually all SGI documentation can be accessed from http://techpubs.sgi.com.

In IRIX 6.5.17, the Remote Shell Daemon (rshd) has been enhanced to check for expired passwords. Users who attempt to access a system using rsh to an account that has an expired password will be denied access. An administrator who is using password expiration no longer has to disable rshd in order to prevent expired users from accessing the system. For information, see the rshd(1M) man page.

The overall behavior of the NFS Version 3 client has been modified to improve mixed and heavy load performance. Most casual users of NFS will probably notice little change. However, users should see a marked improvement in performance under the following conditions:
- Running applications that write large amounts of data over NFS
- Heavy use of bi-directional NFS I/O
- Mixed heavy local disk and NFS I/O
To improve performance under heavy loads, a new set of behaviors have been added that perform the following actions:
- Enable full-duplex NFS traffic
- Prevent read and write starvations
- Provide resource limiting to make the NFS client a fairer user of system resources
These behaviors are based on the notion of fair scheduling of asynchronous NFS I/O to prevent starvations and provide more efficient use of network bandwidth and server disk resources. This also extends to prevent starvations between different NFS mounted directories.

The build_cmgr_script(1M) command generates a cmgr(1M) script from the cluster database. The script can be used later to recreate the cluster database after performing a cdbreinit. For further information, see the build_cmgr_script(1M) man page.

For the IRIX 6.5.17 release, device drivers can create kernel threads not associated with particular interrupts to act as daemons and do background processing. For more information, see the drv_thread_create(3D) man page and the IRIX Device Driver Programmer's Guide, 007-0911-190.

For IRIX 6.5.17, two new options have been added to the cpuset command. The -M option allows the user to move a process or group of processes and their associated memory from one cpuset to another. The -T option allows the user to move a process or group of processes but not their memory from one cpuset to another. For more specific information, see the cpuset(1) man page.

In IRIX 6.5.17, support for following interfaces has been added:
- For nodename-to-address and address-to-nodename translations, getaddrinfo(3), getnameinfo(3), gai_strerror(3), freeaddrinfo(3), getipnodebyname(3), getipnodebyaddr(3) and freehostent(3)
- For interface index-to-name and name-to-index conversions, if_indextoname(3), if_nametoindex(3), if_nameindex(3) and if_freenameindex(3)
These interfaces perform the following functions:
- The getaddrinfo() function translates the node name and/or a service name and returns a set of socket addresses and associated information. This is used in creating a socket with which to address the specified service. It can provide the functionality of gethostbyname() and getservbyname().
- The getnameinfo() function translates a socket address to a node name and a service location.
The above translations are done in a protocol-independent manner to support both IPv4 and IPv6. (Note that IPv6 is not supported in this IRIX release.)
- The gai_strerror() function returns a text string describing an error that is returned by getaddrinfo() or getnameinfo().
- The freeaddrinfo() function frees one or more addrinfo structures returned by getaddrinfo(), along with any additional storage associated with those structures.
- The getipnodebyname() and getipnodebyaddr() functions are for node name to address and address to node name translations for a given address family type.
The getaddrinfo(), getnameinfo(), getipnodebyname() and getipnodebyaddr() functions are thread-safe.
- The freehostent() function frees the memory occupied by the hostent structure that was obtained by a call to getipnodebyname() or getipnodebyaddr().
- The if_indextoname() function maps an interface index to its corresponding name.
- The if_nametoindex() function maps an interface name to its corresponding index.
- The if_nameindex() function returns all interface names and indexes.
- The if_freenameindex() function frees memory allocated by if_nameindex().
For more information, see the getaddrinfo(3), getnameinfo(), gai_strerror(3), freeaddrinfo(3), getipnodebyname(3), getipnodebyaddr(3), freehostent(3), if_indextoname(3), if_nametoindex(3), if_nameindex(3), and if_freenameindex(3) man pages.

Introduced in IRIX 6.5.16:

IRIX 6.5.16 supports a new XThread Control Interface (XTCI) that allows users to control many interrupt thread parameters, including cpu binding. System administrators can use this interface to control kernel thread properties separate from the physical interrupts they service. For information on this interface, see the realtime(5) man page.
For the IRIX 6.5.16 release, performance improvements have been made to the rtmond system monitoring daemon. These improvements will be most noticeable on systems with 128 CPUs and larger. For information on the rtmond daemon, see the rtmond(1) man page.
For the IRIX 6.5.16 release, Array Services scaling support has increased from a maximum of 8 hosts to 64 hosts. Array Services also provides increased interoperability with job limits and new functions such as askillash. For more information, see the Array Services release notes and the array_services( 5) man page and the Array Services chapter in IRIX Admin: Resource Administration.
IRIX 6.5.16 provides support for mice with more than three buttons and mice with wheels. Users with Microsoft Intellimouse or Intellimouse Explorer can use this expanded functionality in many IRIX and Open Source applications. For information on this feature, see the pcmouse(7) man page.
The IRIX 6.5.16 release added an -x[processor] option to the mpadmin(1) command that allows you to exclude the specified CPU from performing any work. This functionality is useful in a situation in which you suspect a CPU may have a hardware error but you do not want to shut down your entire system.
For more information, see the "Excluding a CPU from Performing Work" section in IRIX Admin: System Configuration and Operation and the mpadmin(1) man page.
The IRIX 6.5.16 release includes two new options to the cpr command:
- The IRIX 6.5.16 release includes the cpr -w option that allows you to use the attribute file located in the current working directory (versus $HOME/.cpr). For more information, see the IRIX Checkpoint and Restart Operation Guide and the cpr(1) man page.
- The IRIX 6.5.16 release includes a new -m memory migration option to the cpr command, which allows you to migrate the checkpointed memory to the location in the system topology where the restart operation is executing; for example, within a specific cpuset or within the global cpuset. In addition, a new CKPT_RESTART_MIGRATE restart-related flag has been added for use with the ckpt_restart() library interface function.
  These enhancements to the cpr command and ckpt_restart() library interface provide better functionality when restarting processes within cpusets. For more information on the cpr -m option, see the IRIX Checkpoint and Restart Operation Guide and the cpr(1) man page.
The IRIX 6.5.16 release added a CONTENTS action keyword for the FILE policy of a CPR attribute file. This causes the system to calculate checksum (currently MD5) on the file at checkpoint. Upon restart, the system detects if the file has been modified between begin-of-file and file-size-at-checkpoint; if the file has been modified in this area, the process is refused restart, otherwise, it seeks to the previous offset and continues. For more information, see the IRIX Checkpoint and Restart Operation Guide.
The IRIX 6.5.16 release added two new functions in the Cpuset library called cpusetMove(3x) and cpusetMoveMigrate(3x). The Cpuset library routines, cpusetMove(3x) and cpusetMoveMigrate(3x), can be used to move processes between cpusets and optionally migrate their memory. They allow you to move specific processes, or groups of processes, between existing cpusets, and out of a named cpuset into the pool of CPUs not assigned to any specific named cpuset.
Using this functionality, you can easily destroy existing cpusets to free resources to run a prime job and then easily reconstitute cpusets to continue prior jobs. Because memory used by a process can be migrated to the node associated with the new cpuset, memory locality is improved.
For more information on the cpusetMove(3x) and cpusetMoveMigrate(3x) routines, see Chapter 4, "Using the cpusetMove and cpusetMoveMigrate Functions" in the IRIX Admin: Resource Administration manual and the cpusetMove(3x) and cpusetMoveMigrate(3x) man pages.
The IRIX 6.5.16 release added a disable_uspollsema_chk systune variable for the usopenpollsema(3P) library call. This variable turns off the standard access mode checking on usopenpollsema(3P) (set on the first call to usopenpollsema(3P) via the 'acc' parameter). Some older IRIX applications that were written to work with usopenpollsema(3P) may now require this variable.
For more information, see the usopenpollsema(3P) man page and the /var/sysgen/mtune/kernel configuration file.
The IRIX 6.5.16 release added documentation for the following kernel tunable parameters:
- min_bufmem general parameter
  min_bufmem specifies the minimum amount of memory held by filesystem metadata that is cached in the buffer cache when the system runs into low memory conditions.
- rtcpus dispatch parameter
  rtcpus controls the quality of the real-time scheduler.
- bdflush_interval filesystem parameter
  bdflush_interval specifies the interval at which the bdflush function executes to push dirty file data to disk.
For more information on kernel tunable parameters, see Appendix A in IRIX Admin: System Configuration and Operation.
IRIX 6.5.16 provides support for upgrading license_eoe to the FLEXlm 8.1a release from Globetrotter Software, Inc. The license manager daemon is built in V5 compatibility mode. For more information see the FLEXlm End User Manual and the associated man pages.
IRIX 6.5.16 also provides support for upgrading license_dev to include new optional thread-safe FLEXlm 8.1a client side libraries and headers. For more information see the license_dev release notes.

Introduced in IRIX 6.5.15:

XFS inode numbers are 64-bit values containing an encoded disk location. For large filesystems (1 Terabyte plus), the inode numbers can overflow into the top 32 bits of the number. Certain backup applications which use the inode number only allow 32 bits of space, and thus have severe problems dealing with very large XFS filesystems.
In IRIX 6.5.15, XFS was changed to allocate inodes only within the lower portion of the filesystem to avoid this overflow issue. Other allocation policies in the filesystem will make this lower order space preferred for inodes and reduce the risk of a filesystem refusing to create new inodes when it still has space available.
For existing large filesystems with high numbered inodes this does not solve the problem, but it does solve it for new filesystems, and for new files created on existing filesystems.
For backwards compatibility a new mount option is available, inode64, this will allow xfs to place inodes anywhere in the filesystem and follow exactly the original placement policies. Filesystems which were small enough not to be able to overflow 32 bits of inode number also retain the old behavior.
The IRIX 6.5.15 release added support for disks that have a capacity of 2 terabytes. Previously, the maximum was 1 terabyte. The maximum disk capacity had become an issue with the introduction of 180-GB drives, multiples of which can be combined into a single logical unit (lun) behind a RAID controller.
The maximum capacity of a logical unit for both of our current RAID controllers is 2 terabytes, so this change allows us to support that maximum.
For the IRIX 6.5.15 release, Chapter 5 "System Administration in a Multiuser Environment" in IRIX Admin: System Configuration and Operation was updated with a new section on Project ID numbers and the chproj(1) command that changes the project ownership of a file. The project ID may be either a project name found in the project file, or a decimal project ID. For more information, see the chown(1) man page and the IRIX Admin: System Configuration and Operation manual.
In IRIX 6.5.15 and later, the systune parameter gang_sched_off is turned on by default. This means that gangs will not be running on the system unless the system administrator sets gang_sched_off to 0. This differs from previous IRIX releases, for which gangs ran on the system automatically.
This change has been made per field request because we have discovered that having gang scheduling on by default greatly diminishes system performance. Most customers have been running with it off.
The IRIX 6.5.15 release added a coremask parameter set in the /var/sysgen/mtune/kernel file to determine what kind of permissions a core file will receive. Currently, when a process creates a core file, it uses the umask of the owner of the process to determine the permissions. This can lead to core files containing sensitive information being created with world readable permissions. This systune variable allows the system administrator to limit access to core files. The default is 0, which is the current behavior. However, if the coremask variable is set to some other value, it uses that number as the umask and ignores the umask of the owner of the process. For example, if coremask is set to 0177 and the owner of the process has a umask of 022, the permissions set on the core file will be 600 instead of 644. This variable assumes that the number entered is octal. The default setting is 0. The minimum setting is 0. The maximum setting is 0177.
For more information on the coremask parameter, see Appendix A, "IRIX Kernel Tunable Parameters", in IRIX Admin: System Configuration and Operation.
A new partitioning administration command, partmgr(1M), was added to define and store partition definitions. For more information, see IRIX Admin: System Configuration and Operation.
The IRIX 6.5.15 release added support for the /dev/poll interface for scalable and efficient event notification. For information on /dev/poll, see the poll(7M) man page.
The Dynamic Host Configuration With Proclaim section in IRIX Admin: Networking and Mail was updated to include detailed procedures and descriptions for setting up DHCP.
For the IRIX 6.5.15 release, the DHCP client (proclaim) was updated to include options to allow DHCP clients to capture changes to DNS, NIS, or GATEWAY in your environment. For more information, see the proclaim(1M) man page and IRIX Admin: Networking and Mail.
The IRIX 6.5.15 release provides the ability to designate one or more CPUs or a range of CPUs on a single line in the cpuset configuration file. The CPUs in a cpuset configuration file do not have to be specified in a particular order.
The following is a sample configuration file that describes an exclusive cpuset containing 7 CPUs:
# cpuset configuration file
EXCLUSIVE
MEMORY_LOCAL
MEMORY_EXCLUSIVE
CPU 16
CPU 17-19, 21
CPU 27
CPU 25
For more information on the cpuset configuration file, see Chapter 4, "Cpuset System", in IRIX Admin: Resource Administration.
For the 6.5.15 release, the systune(1M) man page was updated to describe a situation where the system segment size value (syssegsz) reported by the systune command is different than the value set in the /unix file as follows:
The systune(1M) may not show the user-defined value of syssegsz after a system reboot. This is due to the fact that the colormap must be calculated and added to the syssegsz value for machine types IP19, IP20, IP22, and IP32. When systune is called, it compares the value of syssegsz in the kernel to the value set in the /var/sysgen/stune file. If this is done on one of the above machines, the values will not match because syssegsz has been altered with the colormap value in the kernel, but not in the /var/sysgen/stune file. This indicates normal functioning of the operating system.
Starting with the IRIX 6.5.15 release, each partition of a partitioned Origin 3000 system will have a new unique FLEXlm host ID (lmhostid). Any FLEXlm license based on the old non-partitioned lmhostid value will no longer work and a new license key must be generated. See the following web page for additional details, http://www.sgi.com/support/licensing/.
- Contact the applicable software product vendor and provide the lmhostid number of the partition to generate a new license key. For nodelock licenses, provide the lmhostid for all partitions of the software installed and operating.
- For software licensed by SGI, see the following web page for more details:
  http://www.sgi.com/support/licensing/.
- For e-mail and telephone contact information, see the Bundled software page.
For IRIX 6.5.15 we added HOTPLUG attach and detach support for SGI Gigabit Ethernet Network adapters. This feature is supported on IP35 Origin 3000 series systems only; it is not supported on IP35 0300 systems. For information on this feature, see IRIX Admin: Networking and Mail.
The IRIX 6.5.15 release supports the lmparthostids and lmbasehostid commands. The lmparthostids command generates a list of all 63 partition specific hostids and the unpartitioned id. This list can be passed to a license key generation tool for nodelock licenses so that the license works across all partitions or an unpartitioned system. The lmbasehostid command takes any arbitrary lmhostid (this could be a partition specific value) and generates the base unpartitioned id. That number could be used when the base lmhostid is required, even from a partition.
FLEXlm v7.2i support from GLOBEtrotter Software, Inc. was added. The license manager daemon and the floating license server are built in V5 compatibility mode. For backwards compatibility, the client libraries and header files are still based on FLEXlm v6.1g. For more information, see the FLEXlm End User Manual and the associated man pages.

Introduced in IRIX 6.5.14:

In the IRIX 6.5.5 release, SGI introduced a new optional directory format for XFS filesystems, referred to as the "version 2" directory format in mkfs output.
XFS filesystems with a version 2 directory format can provide improved reliability and performance over filesystems with a version 1 directory format in some applications, particularly for applications that use NFS exported XFS filesystems.

The directory format for an XFS filesystem is specified with the -n parameter of the mkfs command. The default directory format is currently the original version 1 directory format.

Beginning with the IRIX 6.5.14 release, version 2 directories of XFS will be the default for all new filesystems created with mkfs. Version 1 directory filesystem creation will still be supported, but this will require that you specify the -n version=1 parameter of the mkfs command.

SGI recommends that all new XFS filesystems be created with version 2 directories. IRIX releases older than IRIX 6.5.5, however, will not be able to mount a filesystem created with a version 2 directory and will issue the following message when a mount is attempted:

Wrong filesystem type: xfs

Many SGI customers are currently running production servers with version 2 directories. If you want to format filesystems with the version 2 directory format prior to the IRIX 6.5.14 release, you can specify the following option of mkfs:

mkfs -n version=2

There is no means for converting a filesystem, in place, between version 1 and version 2 directories. A filesystem can be converted between version 1 and version 2 directories by means of an xfsdump/mkfs/xfsrestore sequence.

For more information, see IRIX Admin: Disks and Filesystems.
In IRIX 6.5.14, added a -q cpuset_name -p option to the cpuset command that allows you to see the properties of particular cpuset, such as, the number of processes and CPUs associated with the specified cpuset.
In IRIX 6.5.14, added cpusetGetProperties( ) and cpusetFreeProperties( ) functions to the Cpuset System library .The cpusetGetProperties( ) function allows you to retrieve various properties associated with a cpuset. The cpusetFreeProperties( ) functions allows you to release the memory used by a cpuset_Properties_t structure. Any programmer that uses the cpuset API from IRIX 6.5.14 and later, can use these functions. For information, see chapter 4, "Cpuset System", in the IRIX Admin: Resource Administration manual and the cpusetGetProperties(3x) and cpusetFreeProperties(3x) man pages.
Parts of the IRIX Interactive Desktop were refreshed in IRIX 6.5.14. While functionality has not changed, the navigation, imagery, and graphics design have been enhanced in the following areas:
- The main IRIX login window (clogin) has a new design using new SGI colors, font, and logo. The product is called sysadmdesktop and appears automatically at boot when root has "chkconfig noiconlogin on".
- EZsetup has a new layout and login icon using new SGI colors, font, and logo. The product is called sysadmdesktop and is launched by logging into EZsetup account from main IRIX login window.
- The System Manager main window uses new SGI colors, font, and logo. The product is sysadmdesktop and is launched from the System toolchest.
- The Welcome to SGI web pages have new navigation and new SGI colors, font, and logo. The product is Welcome. Launch from Find toolchest, select WhatsNew, double-click the Welcome_to_SGI icon.
- The Background Setting panel includes seven new desktop patterns using the new SGI logo and font: Camouflage, Citrus Citrus, Iron, Midnight, Reef, Sand, and Sprinkle. Note: You may notice slow performance when previewing all but the Sprinkle background, but not when switching desks (see the background(1) man page). Old backgrounds are still available. The product is desktop_eoe and is launched from the Desktop toolchest, select Customize, then Backgrounds.
SCSL is a collection of high-performance mathematical and numerical libraries that are widely used in scientific and technical compute intensive applications. An iterative solver for sparse systems of linear equations, as well a direct solver for sparse complex symmetric systems of linear equations, have been added to the SCSL 1.4 release. Additional features added to SCSL for this release are as follows:
- A thread-safe parallel random number generator
- Fortran90 interfaces to the BLAS
- A parallel implementation of the solve phase for the out-of-core sparse solver
- Removal of all entry points to the CHALLENGEcomplib FFT routines
- Performance enhancements and rollup bug fixes from SCSL 1.3.
SCSL can also be downloaded free of charge from the Download Cool Software page at http://www.sgi.com/products/evaluation/.

For more information on SCSL, see http://www.sgi.com/software/scsl.html.

For customers who do not have web access and are enrolled under a valid support contract, CD media can be requested free of charge from their local support center. Non-contract customers can order SCSL from their local sales representative.

Introduced in IRIX 6.5.13:

The xfsrestore command returns an incorrect exit code when it encounters a media error; improving this process lets a system administrator intelligently react to these conditions.
Improved exit codes for the xfsrestore and xfsdump commands. This lets a system administrator correctly respond to end-of-media or operator interrupt conditions
Changed the mkfs command to allow you to specify the size of an XFS allocation group, as an alternative to specifying the total number of allocation groups. You use the -d agsize= option for this. For information, see the mkfs_xfs man page and IRIX Admin: Disks and Filesystems.
Changed the mkfs command to allow you to specify the size of a stripe unit and the size of a stripe width in bytes or in filesystem blocks, as an alternative to specifying these values in 512-byte block units. You use the -d su= and the -d sw= options for this. For information, see the mkfs_xfs man page and IRIX Admin: Disks and Filesystems.
Changed the default size of an XFS allocation group; larger filesystems will result in larger default allocation group sizes.
The xfsdump and xfsrestore commands will provide the VSN of the tape that reached its end-of-volume (or the VSN of a new tape that needs to be mounted) and pass this VSN to the media_change_alert_program specified with the -c option. This lets system administrators send commands to a tape jukebox to mount the next tape.
Changed the default size of an XFS log. The default log size grows with the size of the filesystem up to the maximum log size, 128 megabytes, on a 1 terabyte filesystem. For information on the default values of XFS allocation groups and XFS log sizes, see IRIX Admin: Disks and Filesystems.
Added cpusetAttachPID( ) and cpusetDetachPID( ) functions to the Cpuset System library. The cpusetAttachPID( ) function allows a programmer to attach a currently running program to an existing cpuset. The cpusetDetachPID( ) function allows a programmer to detach a currently running program to an existing cpuset. Any programmer that uses the cpuset API from IRIX 6.5.13, and later, can use these functions. For information, see chapter 4, "Cpuset System", in the IRIX Admin: Resource Administration manual and the cpusetAttachPID(3x)and cpusetDetachPID(3x) man pages.
The following features have been moved from Enhanced DHCP to standard DHCP:
- Ping check before an address is leased to insure it is not already in use
- MAC address filtering; clients whose MAC address is listed in a file will be unable to obtain a lease and/or accesses from these clients will be logged.
For more information, see the dhcp_bootp man page.
Added implementation of End Sequence to Scheduled Transfer Protocol. The upper layer protocol or applications can now terminate a transfer and restart another one without taking down virtual connection.
VPro for Octane and OpenGL performance improvements have been added as follows:
- Improved X window performance by 25 percent based on x11perf
- Iproved performance of OpenGL glCopypixel( )) function
The following new system controller features have been implemented for the SGI Origin 3000 server series:
- Enabled router port security, which prevents unauthorized enabling of additional router ports on router bricks in the SGI Origin and Onyx 3400 server series
- Enabled system serial number security, which prevents unauthorized changes to the system serial number
- Completely redesigned the graphical interface for the front-panel display of the SGI 3400 and 3800 servers
Added hotplug attach feature that allows Gigabit Ethernet cards to be installed on a running system. A system administrator can use the pciconfig command to add cards to an Origin 3000 system and the ifconfig command to configure the cards for networking. For more information, see the pciconfig and ifconfig man pages.
Added Origin 3000 system partitioning support in the eoe.sw.partition software package. This feature improves how system partitioning software is installed, enabled, and disabled. It also eliminates the need to manually edit configuration files.
Efficiency improvements have been made to the BTE driver layer to reduce both latency and contention. This feature is a performance improvement to the existing functionality that is used internally by the system.
The tools that report CPU utilization have been modified to correct the sampling of %WIO to omit idle time in line with industry standards. See the sar(1) man page for details.
Updated FLEXlm v7.2f support from GLOBEtrotter Software, Inc. The license manager daemon and the floating license server are built in V5 compatibility mode. For backwards compatibility, the client libraries and header files are still based on FLEXlm v6.1g. For more information, see the FLEXlm End User Manual and the associated man pages.

Introduced in IRIX 6.5.12:

OpenGL Performer 2.4.1 execution environment, which is a powerful suite of tools and features that creates real-time visual simulation and other professional performance-oriented 3D graphics applications for the IRIX operating system. The following new features for OpenGL Performer provide enhanced realism and peak-performance rendering:
- Programmable model shading using pfShader
- Use of pfVolFog for rendering layered and patchy fog
- Use of pfRotorWash to create the visual effect of downwash in helicopter simulation
- Double-precision matrix support for rendering extremely large databases where objects are far away from the origin
- CPU priority specification to allow multiple run-time processes to run on the same processor
- Multi-pipe scalability enhancements
- Improved pfLOD behavior to allow custom evaluation functions
- Speed and functionality enhancements for pfFlux, pfCliptexture, and pfLightpoints
- pfHyperpipe support for the DPLEX hardware option
- EventView performance tuning tool for instrumenting and tuning your OpenGL Performer application
The IRIX tape-support feature consists of a tape support driver, personality daemons, and a daemon that manages the personality daemons. The feature enables new personality daemons to be developed and added individually. The tape-support driver, which co-exists with the current IRIX tape driver (tpsc), passes all device-dependent tasks, except for I/O processing, to a personality daemon. This release supports various devices including the Fibre Channel implementation on the StorageTek 9840 and T9940A tape drives. The reserve, release, preempt, clear, and prsv commands are available for these tape drives on the mt command. For more information, see the mt(1), tsarchive(1M), tsdaemon(1M), tserrpt(1M), tsset(1M), tsstop(1M), ts.config(4), and ts(7) man pages.
Updated FLEXlm v7.2e support from GLOBEtrotter Software, Inc. The license manager daemon and the floating license server are built in V5 compatibility mode. For backwards compatibility, the client libraries and header files are still based on FLEXlm v6.1. For more information, see the FLEXlm End User Manual and the associated man pages.
The Scheduled Transfer Protocol (STP) has moved from the feature stream to the maintenance and feature stream. STP is now a mature supported protocol and it includes TRIX support.

Introduced in IRIX 6.5.11:

Support for the use of a reserved area of memory; this reserved area is between virtual addresses 0x30000000 and 0x40000000. This feature disables the reserved area of memory that the kernel provides for applications to place their mmap and shmat mappings. For more information, see the mmap(2), shmat(2), syssgi(2), and sgi_use_anyaddr(1) man pages.
Support for weightless pthreads; they allow you to lower the priority of a process by using the npri -w command. For more information, see the npri(1) man page.
Support for upgrading license_eoe to the FLEXlm 7.1 release from Globetrotter Software, Inc. The license manager daemon will be built in V5 compatibility mode. For more information, see the FLEXlm End User Manual and the associated man pages.
Support for an increased maximum number of logical unit numbers (LUNs) in the SCSI infrastructure from 64 to 255. This change impacts only the fcadp and qlfc fibre channel drivers and they will now enforce this LUN limit. If a LUN is greater than 255, it will be ignored after issuing a message to this effect. If you use large numbers of LUNs, you can exhaust the hardware graph. You may need to use the systune command to increase the hwgraph_num_dev parameter to let the kernel build larger hardware graphs.
Support for licensing of partitioned environments. The SGI Origin 3000 server series and SGI Onyx 3000 series of systems give you the flexibility to distribute and manage a partitioned system environment on a large CPU server system. In most cases, software licensing behaves in the same manner on a single system image as in a partitioned environment. However, there are some differences. Depending on your applications, you may need either systemwide or per-CPU licensing. For more information, see IRIX Admin: Software Installation and Licensing.
Support for the PCI Hot Plug infrastructure on the SGI 3200, SGI 3400, and SGI 3800 servers. The Hot Plug feature consists of the Hot Insertion and Hot Removal actions. Each device driver must be qualified as supporting one or both of these actions. Currently, the QLogic fibre channel and QLogic SCSI device drivers are qualified for Hot Insertion. For more information on specific administrative options, see the pciconfig(1) man page.

Introduced in IRIX 6.5.10:

Support for point-to-point connections between the QLogic 2200 fibre channel controller and the Brocade switch. This type of connection lets the QLogic 2200 controller perform full duplex transfers with the switch offering a potential increase in bandwidth. This capability was enabled by changing the value assigned to the qlfc_use_connection_mode variable (in /var/sysgen/master.d/qlfc) to 2. The previous value was 0. This change does not impact loop operation.
Support for the IRIX SCSI tape driver (tpsc) enhancements that let system administrators and privileged applications specify a persistent reservation on shared tape drives. After the reservation has been established, the shared tape drive cannot be accessed by another host until the reservation has been released. For more information, see the mt(1) and mtio(7M) man pages.
Support for the new Fortran, C++, and base compiler runtime libraries packaged under the ftn_eoe, c++_eoe and compiler_eoe overlay images. These libraries are based on the MIPSpro 7.3.1.2m compilers and contain new interfaces released under the MIPSpro 7.3 compilers. The libraries are backward compatible with the libraries that were released in previous versions of IRIX 6.5. For more information, see the ftn_eoe, c++_eoe, and compiler_eoe release notes.

Introduced in IRIX 6.5.9:

Support for Embedded Support Partner 2.0 (ESP2.0). This release supercedes patch 3895 and includes the major features as follows:
- Automatic Call Logging to the SGI call centers for Mission Critical Supported customers
- Support of event profiles for monitoring
- A new command line interface to setup and use ESP
- A new user interface with a high level of usability and navigational features
- Fixes to the System Group Manager for secure interconnectivity between group members and the group manager
- Support for an unlimited number of group members to the System Group Manager
- Multiple ESP user support with page privileges
- ESP logbook for electronically logging and tracking support activities locally on the system
The migration from ESP1.0 to ESP2.0 is done seamlessly when upgrading from previous versions of IRIX to IRIX 6.5.9.

The Embedded Support Partner Overview and the Embedded Support Partner User Guide have been combined. The new document is called the Embedded Support Partner User Guide and will contain overview and usage information for the ESP 2.0 command line and graphical user interfaces.
Support for the SCSI Enclosure Services (SES). A new subsystem that manages the Fibre Channel drive enclosures has been added. The new daemon, sesdaemon, supports the Xyratex 12-slot enclosure and the Clarion 10-slot enclosure. The new client application, sesmgr, uses a command set similar to the set used by the previous fcagent/fccli subsystem. For more information, see the sesdaemon(1M) and sesmgr(1M) man pages.

Introduced in IRIX 6.5.8

Support for 32-bit direct mapping to any node on the system. This feature lets the system administrator change the 32-bit direct mapping node for a specific Peripheral Component Interconnect (PCI) bus. It also provides a new interface, pcibr_get_dmatrans_node( ), that lets a device driver obtain the node ID. For more information, see the IRIX Device Driver Programmer's Guide and the pcibr_get_dmatrans_node(D3) man page.
Support for the Cpuset System programming interface application (previously known as miser_cpuset). This interface is provided in the form of a Dynamic Shared Object (DSO). You can use this programming interface to create cpusets, remove cpusets, and attach processes to cpusets. You can use the cpuset programming interface in areas where the cpuset command is inappropriate. For example, if a batch system needs to use the cpuset capability in IRIX, the programming interface will provide a more flexible and robust solution than the cpuset command. For more information, see IRIX Admin: Resource Administration and the cpuset(5), cpusetAllocQueueDef(3x), cpusetAttach(3x), cpusetCreate(3x), cpusetDestroy(3x), cpusetDetachAll(3x), cpusetFreeCPUList(3x), cpusetFreeNameList(3x), cpusetFreePIDList(3x), cpusetGetCPUCount(3x), cpusetGetCPUList(3x), cpusetGetName(3x), cpusetGetNameList(3x), and cpusetGetPIDList(3x) man pages.
Support for new Miser cpuset options. These options allow the creation of restrictive memory pools from the nodes that contain the CPUs listed in the configuration file. Processes that exceed the available memory on those nodes may be terminated or paged (selectable). For more information on these options, see the cpuset(4) man page.

Introduced in IRIX 6.5.7:

Support for the IRIX sendmail mail system based on sendmail version 8.9.3 (see http://www.sendmail.org). Some of the new functions in version 8.9.3 are as follows:
- The major difference between sendmail versions 8.8.8 and 8.9.3 is their configuration file. The configuration file in sendmail version 8.9.3 is configured with the sendmail.mc file which is processed with the m4 macro processor to create the sendmail.cf file.
- A new version of configmail configures the sendmail.mc file and provides features similar to the configmail utility in previous versions of IRIX. This version of configmail also processes the sendmail.mc file into sendmail.cf by using the m4 macro processor.
- Sendmail 8.9.3 includes many new features requested by IRIX users, such as anti-relay features which can be used to control spam messages.
For more information on the 8.9.3 version of sendmail, see the IRIX Administration: Networking and Mail manual. For more information on how to configure sendmail, see http://www.sendmail.org/m4/readme.html. The sendmail feature was initially added to the IRIX 6.5.7 release.
Integration of the fsr_xfs(1M) command into the fsr(1M) command. With previous releases of IRIX, the fsr command could be run only on EFS filesystems and the fsr_xfs command could be run only on XFS filesystems. Both commands reorganize filesystems so that the layout of the extents is improved. This improves the performance of mounted filesystems that have become fragmented over time. With this release, the fsr command invokes fsr_xfs when it encounters XFS filesystems. With this change, the default crontab(1M) entry that calls fsr, also reorganizes XFS filesystems. For information on the fsr command and the fsr_xfs and fsr_efs options, see the fsr(1M), fsr_xfs(1M), and fsr_efs(1M) man pages.
Support for the -u option of the sat_interpret utility that writes unbuffered output. You can use this new option if you are using the sat_interpret utility to process system audit trail data, and then you can pipe this output to another filter utility. For more information, see the sat_interpret(1M) man page.
Support for bzero error recovery; this RAS feature prevents the kernel from panicking when a memory Multiple Bit Error (MBE) is encountered while the kernel is zeroing out a new page in the virtual memory fault handler (vfault). The kernel will now discard the page with the memory error, grab a new page, and continue its task.

Introduced in IRIX 6.5.6:

Support for a multithreaded version of the automatic filesystem mount daemon autofsd. This enhanced functionality allows for simultaneous multiple automounts. If a particular server for an automounted filesystem is not running or is slow to respond, one autofsd thread can wait for that server while other autofsd threads mount filesystems from other servers. This capability improves the automount performance and simultaneously provides longer wait times for downed servers, which should lead to a decrease in automount failures.

Introduced in IRIX 6.5.5

Embedded Support Partner, which is an integral part of the IRIX operating system, provides system administrators with a way to monitor various events (such as system events, changes in system hardware and software configuration, and system performance) that can occur on their system. Embedded Support Partner consists of a set of daemons that perform the monitoring activities. These include an event monitoring daemon (eventmond), an event management daemon (espemd), and a database daemon (espdbd). Embedded Support Partner provides single system monitoring capabilities as a standard part of IRIX. Optionally, Embedded Support Partner can be configured to receive event and system configuration data from all systems contained within a system group. Embedded Support Partner is controlled through a Web browser that is connected to the Configurable Web Server that is included in the Embedded Support Partner package. For more information, see the Embedded Support Partner Overview, the Embedded Support Partner User's Guide, and the Embedded Support Partner man pages.
Support for the version 2 XFS directory format; this format provides you with the capability to choose a filesystem block size to match the distribution of data file sizes without adversely affecting directory operation performance. The directory format is specified with the -n parameter of the mkfs command. For more information, see the IRIX Admin: Disks and Filesystems and the mkfs_xfs(1M) man page.
SCSL version 1.2 supports features such as convolution/correlation and filter routines to the Signal Processing functionality. Additional IRIX features added to SCSL for this release are improved ordering techniques for the sparse linear solvers, performance enhancements for the MIPS R12000 processor, rollup bug fixes from SCSL 1.1, and all other Challengecomplib 3.1 functionality.
Support for Automated Performance Monitoring. Together with Embedded Support Partner, the base performance monitoring services in the pcp_eoe product have been extended to include an inference engine for evaluating rules about system-level performance and raising alarms. Also provided is a parameterized set of standard rules that can be selectively enabled and tuned to meet local requirements and to choose alternative alarm notification mechanisms. These features are of most value to operations staff running production IRIX systems. For more information, see the pmie(1) and pmieconf(1) man pages, and the Performance Co-Pilot(TM) IRIX Base Software Administrator's Guide.
Two new options were added to the "miser_create_cpuset" command. These options allow additional restrictions on memory assignment for processes running on a cpuset. These options are documented in the miser_cpuset(4) man pages.
Support for SAN addressing

Introduced in IRIX 6.5.4:

Support for the Miser queue repack policy. When a job finishes execution prior to the end of its schedule, the system resources it was using are released. This policy attempts to reschedule the jobs using earlier start and end times in order to take advantage of these released system resources. The order of the scheduled jobs will be maintained.
