- As promised here is a list of criteria to look at when considering a
- program to be submitted to SPEC for consideration as an application
- benchmark. This is not intended to be an exhaustive list, in fact it is
- only this author's opinions. This list has not been 'blessed' by the SPEC
- steering committee. If your program does not meet on all criteria, it
- doesn't mean an automatic rejection, it just depends on how much work we
- need to do to make it acceptable and how appealing your application is to
- SPEC. After your program has been submitted as a candidate program, the
- Steering Committee will need to find a sponsor (a Steering Committee
- member) and a project leader (who will actually do the work).
-
- Submit Permission forms and/or programs to one of the following:
- rnovak@mips.com, shanley@cup.portal.com. We will reply ASAP (remember that
- next week is UniForum). Include e-mail, U.S. Mail telephone and FAX
- numbers as applicable or possible. To request a more information on SPEC,
- call 1-415-792-2901.
-
- Criteria
-
- 1. The program should be an application-oriented program,
- i.e. a program that is frequently used by an active
- user community.
-
- 2. Each program must be a key component in a long-range
- goal to test overall processor/system performance.
- SPEC wants to exhaustively exercise not only the CPU
- and FPU, but also the Disk I/O, Tape I/O and Network
- I/O as well as the operating system scheduler.
-
- 3. Each program must be a representative component in a
- wide-range of applications. SPEC wants representative
- programs from scientific (CAD, ECAD, MCAD, Seismic,
- Nuclear Physics, Astronomy, etc.), Technical (CASE,
- compilers, CPU simulators, debuggers, software
- development aids, etc.) and commercial applications
- (Accounts Receivable, MRP, ISAM files, RDBMS based MIS
- applications, flight scheduling programs, distribution
- routing (trucking, railroads), etc.).
-
- 4. Each program should be large, in terms of total
- program size, size of most compute-intensive block and
- in terms of the total working set size of both the
- instruction set and the data reference set.
-
- All too many performance tests have squeezed into on
- board CPU caches, which may not be representative of
- actual applications.
-
- 5. The programs should be long-running programs (greater
- than 60 seconds of execution time on a 10 mip CPU).
- Programs that use less CPU time than that will result
- in measurements that are below the resolution of
- system timer programs. In addition, these
- applications for performance testing will hopefully
- have a lifetime that exceed 18 months of meaningful
- duty.
-
- 6. Whenever possible, the program should be public domain
- or it should be made publicly available under the SPEC
- license umbrella. This is the part that makes the
- SPEC job the hardest. A software developer must be
- willing to allow the competition to examine at least
- some part of their source code in order to make the
- code available to SPEC.
-
- 7. The program must be easily portable to many machines.
- A program that is developed for the UNIX (R)
- environment is usually the simplest to port to most
- platforms.
-
- 8. The program's output must be mechanically checkable
- for correctness. The benchmarks are useless unless we
- can verify that they produce identical results.
-
- 9. The programs' source code should conform to existing
- language standards for the implementation language.
- In attempting to move the SPEC benchmarks from 32 bit
- platforms to 64 bit platforms, SPEC has discovered
- that this was the greatest sin in Release 1.0.
