Short: UNIX-like process scheduler (V2.00)
Author: petrin@megabaud.fi (Petri Nordlund)
Uploader: petrin@megabaud.fi (Petri Nordlund)
Version: 2.00
Type: util/misc
Requires: AmigaOS 2.04
Replaces: util/misc/Executive.lha
Executive brings real multitasking to AmigaOS. Executive is a
UNIX-like process scheduler for Amiga. It also has plenty of other
features previously available only in larger operating systems.
Executive improves the responsiveness of your Amiga. One CPU
intensive application no longer causes the whole system to crawl.
You can start many CPU intensive applications and the system still
feels as if it would be totally idle.
The Executive package also includes many useful client programs
that let you control tasks and monitor what is going on in your
system.
The core of Executive is a scheduler that recalculates task
priorities based on system load average and task's recent CPU
usage. The scheduler will give high priority to interactive tasks
and low priority to CPU intensive tasks.
Lets say you are printing a document from a word processor. You
can't do much else while the document is being printed. This isn't
multitasking. With Executive you could also do some heavy rendering
and C-compiling in the background at the same time. You could surf
the web with your favorite browser without even noticing all these
programs running in the background.
Executive consists of a server and clients. The server is run
in the background and it takes care of scheduling, CPU usage
calculations and many other things. Some important features of
the server:
- precise (1/1000 seconds) CPU usage timing
- six different scheduling algorithms
- load averages
- process identifiers
- process group identifiers
- accounting
- focus - task with active window gets more CPU time
- MultiUser support
The client programs are:
Acct Accounting daemon
ALoad Display load average or CPU usage
ALoad3D Display load averages in 3D
Commander General task manager
Ctp Extended ChangeTaskPri
Dashboard The mother of all meters
Kill Extended Break
Lastcomm List last commands executed
Meter Display system information
Nice Run programs with lower scheduling priority
Ps Process status displayer
Pstree Display child-parent relationships
Renice Renice a task
Sa Display accounting statistics
Stat Display some misc. information
Timer Time shell and Workbench programs
Top Display information about top CPU tasks
Uptime Display system uptime and load averages
Executive is fully compatible with all Amiga computers running AmigaOS
release 2.04 or newer.
Executive is the highest rated item of shareware CU Amiga magazine
has ever awarded at 98%.
----------------------------------------------------------------------
The most notable changes in this release are:
- Schedulers have been improved and a real multi-level feedback
queue scheduler, found on most UNIX systems, is now available.
- New client, Dashboard, lets you open multiple windows and
interactively create all kinds of meters on them and adjust
their parameters. Everything is user configurable.
- PatchControl and ScreenNotify support.
- CPU usage can be displayed with Amiga's power LED.
- The server and some clients are now commodities. Scheduling
can be disabled and enabled without restarting the server.
- ExecutiveAPI is a new low-level API for application programs
that wish to directly control scheduling.
- A small tutorial is included.
- Tasks can now be scheduled as a group, if necessary.
