Script for "Attack Alpha" slide presentation
--------------------------------------------
Slide 1: DEC's Financials implicate that there will be future R&D
cuts with people layoffs of over 20,000 employees. Cutbacks may
impact OSF/1 environment development on the new Alpha AXP platforms.
The sales and support staffing at DEC will also be cut back, meaning
that small to mid-size companies may be dealing with third-party
companies for software solutions and support, rather than DEC's direct
sales and support staff.
Slide 2: Although DEC strongly emphasizes that migration from the
DEC VAX lines or DECsystem lines to Alpha will be easy, customers
should consider the facts.
. Full production environments for either OSF/1 or OpenVMS
will not be ready on Alpha platforms until 1994 at the
earliest.
. Using tools like DEC's translator "VEST" will not provide
100% efficiency. Translated code on an Alpha will run only
as fast as it would on a VAX, best case. In addition, VEST
will only flag problem areas in the code, such as detecting
unaligned data, floating point references, non-standard
coding practices, references to VMS data, etc. All these
problem areas will have to be modified by the programmer in
the original source code. There are also several problems
that VEST cannot detect, such as synchronization problems,
page-size dependencies, etc -- all of which can cause
catastrophic problems during runtime.
. This is the first time DEC has ever developed RISC-based
compilers -- and it will be impossible for DEC to tune it
optimally on first release. RISC compiler technology takes
1-2 years or more to tune, as past history proves. Keep in
mind that DEC will need to tune three separate operating
system environments for Alpha.
. DEC will not have SMP support on Alpha until mid '93.
. C, Fortran, and COBOL programs will require source code
changes since there are a number of differences in the
languages and compilers on Alpha from what they were on VAX
or DECsystems.
Conclusions of the above points are that:
1. At this time, there are very few ported applications to
Alpha. Only 50-75 are estimated to exist, with 500 planned
by mid '93 and 1000 by the end of '93. Compare that to the
thousands of applications available with HP-UX.
2. Since several of the languages and development tools have
not been ported to Alpha, as the next slide shows,
application development on Alpha is difficult if not
impossible.
3. Given the problems with translated code using "VEST", the
fact that DEC has yet to release OLTP benchmark data on
Alpha, and unproven RISC compilers, significant application
performance improvement by porting to Alpha can't be
guaranteed.
Slide 3: OSF/1, OpenVMS for AXP (Alpha) lag HP-UX by at least 1-2
years, in the categories of symmetric multiprocessing, full
language support, networking services, high availability, TP
monitors, and DCE services. These capabilities are required
by in most mission critical commercial computing
environments and clearly illustrates that Alpha platforms
will not be suitable in these environments until mid 1994 or
later.
Slide 4: Our Alpha AXP vs. HP PA-RISC performance comparison between
comparably positioned models in the HP 9000 line and Alpha
AXP line shows comparable technical performance as measured
in SPECint92 and SPECfp92 benchmarks. DEC has not released
any commercial benchmark information on the Alpha systems.
However, according to our best estimates on Alpha OLTP
performance, we have performance positioned the Alpha
systems with our HP 9000 line.
Slides
5-6: As can be seen from these slides, the multiprocessor
configurations for Alpha systems are not available until
around mid '93. These future systems are shown on these
slides as having comparable performance to our present HP
9000 systems. In 1993, HP will be making significant
performance enhancements to the present line with higher
levels of PA 7100 multiprocessing.
Slide 7: Key questions that customers should ask DEC when evaluating
Alpha AXP systems should be:
1. Why has DEC not published commercial benchmark results
for Alpha AXP? There has been some speculation by
consultants that DEC has not been able to get an acceptable
level of OLTP performance scaling and that RISC compilers
have not been optimally tuned as of yet. Any customer
considering these platforms for commercial environments
should be looking at more appropriate measures of
performance like TPC-A rather than the technical SPEC
benchmark results DEC has been publishing.
2. When will full functionality OpenVMS and OSF/1 really be
available on Alpha AXP? Without a full suite of application
development tools, languages, networking, etc., these
platforms are not really viable for mission critical
production commercial environments.
3. What is DEC's commitment to UNIX capability? Right now,
DEC does not have a production quality high-performance UNIX
environment available. It's DECsystem line has a high-end
commercial performance of only around 30 TPS. An end-user
production quality OSF/1 operating system will not be
available on Alpha until Q2 '93 and a full functionality
environment for OSF/1 on Alpha will not be ready until 1994
or later.
4. When will a robust application portfolio be available on
Alpha AXP? At present there are only around 50 applications
that have been ported to Alpha. At the end of '93, only
DEC is claiming to have around 1000 applications ported.
Yet only one third of these are expected to be OSF/1 based.
