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


To run and install SPEC OMP2001, you will need:

   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.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. 

   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-90 or Fortran-95 compilers

       --or--

       b. 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.
