------------------------------------------------------------------------


To run and install SPEC HPC2002, you will need:

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

   2. A CD-ROM drive 

   3. Main Memory: 
        Medium size: 1 GB of RAM
        Large size:  4 GB 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:

        Medium size: 8 GB of disk space to install and run the suite
        Large size: 80 GB of disk space to install and run the suite
  
        * Minimum requirement: It is possible to run with less 8GB 
	  if you run the small or medium data sets and clean up the run 
          directories between experiments; see runspec.txt for more 
          information.  If you have not yet installed the suite, you 
          can find runspec.txt on the CD in /docs or \docs.nt.  After 
          installation, runspec.txt may be found in 
          $SPEC/docs/runspec.txt (Unix) or %SPEC%\docs.nt\runspec.txt (NT).

        * More disk space will be needed if you plan to maintain a large 
          set of binaries and run directories.

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

       a. A set of compilers for the result(s) you intend to measure:

          Both C and Fortran

       --or--

       b. A pre-compiled set of benchmark executables, given to you
          by another user of the same revision of SPEC HPC2002, and
	  and any run-time libraries that may be required for those 
	  executables.




      Please notice that you cannot generate a valid HPC2002 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 wrf benchmark
      but lack a Fortran compiler, you will not be able to measure
      a HPC2002 result.
      


Portability Notes:

   SPEC HPC2002 is a source code benchmark, and portability of that source
   code is one of the chief goals of SPEC HPC2002.  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 (e.g. Fortran-77 is not a
         valid form of Fortran).

       - 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 HPC2002,
   you will find combinations of OS and compiler versions that are known
   to work.  For example, if a vendor reports a SPECwrfM2002 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 HPC2002 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.
