SPEC OMP2001 Hardware and Software Requirements

Last updated: 17 Apr 2001 2pm wj (To check for possible updates to this document, please see http://www.spec.org/hpg/omp2001 )

1. A computer system running a UNIX or Windows NT environment. (See the Portability Note below)

2. A CD-ROM drive

3. For the OMPM2001 suite (Medium size): 2.0GB of RAM.
   For the OMPL2001 suite (Large size): 8.0GB of RAM

   Attempting to run the suite with less memory is strongly discouraged, as you will end up measuring the speed of your paging file, not the speed of your CPUs.

4. Disk space:

   • Typically 10GB of disk space to install and run the suite including swap.
   • Minimum requirement: It is possible to run with about 2GB (8GB for the large dataset) if you clean up the run directories between experiments; see runspec.html for more information. If you have not yet installed the suite, you can find runspec.html on the CD in /docs or \docs.nt. After installation, runspec.html may be found in $SPEC/docs/runspec.html (Unix) or %SPEC%\docs.nt\runspec.html (NT).
   • More disk space will be needed if you plan to maintain a large set of binaries.

5. Since SPEC supplies only source code for the benchmarks, you will need either:

   1. A set of compilers for the result(s) you intend to measure:
      Both C and Fortran-90 or Fortran-95 compilers
      
      --or--

   2. A pre-compiled set of benchmark executables, given to you by another user of the same revision of SPEC OMP2001, and and any run-time libraries that may be required for those executables.

Please notice that you cannot generate a valid OMP2001 result unless you meet all of requirement 5.a.1 or 5.a.2 or 5.b. For example, if you are attempting to build the medium suite but lack a Fortran-90 compiler, you will not be able to measure a OMP2001 result.

Portability Notes:

SPEC OMP2001 is a source code benchmark, and portability of that source code is one of the chief goals of SPEC OMP2001. SPEC has invested substantial effort to make the benchmarks portable across a wide variety of hardware architectures, operating systems, and compilers.

Nevertheless, certain portability problems are likely to occur from time to time. For example:

• Some older compilers may not include all the features needed to run the entire suite.
• Sometimes, a new release of a compiler or operating system may introduce new behavior that is incompatible with one of the benchmarks.

If you visit http://www.spec.org and look up results for SPEC OMP2001, you will find combinations of OS and compiler versions that are known to work. For example, if a vendor reports a SPECompMbase2001 result on the SuperHero 4 using SuperHero Unix V4.0 with SuperHero C V4.0 SuperHero Fortran V4.0, you may take that as an assertion by the vendor that the listed versions of Unix, C, and Fortran will successfully compile and run the SPEC OMP2001 suite on the listed machine.

For systems that have not (yet) been reported by vendors, SPEC can provide limited technical support to resolve portability issues. See $SPEC/docs/techsupport.txt or %SPEC%\docs.nt\techsupport.txt for information.
