    Below are 2 CPU stream results for an HP ProLiant DL145, configured as
    follows:

    HP ProLiant DL145
    4x2.4GHz 240 Opteron processors
    16GB PC2700 memory (8x2GB DIMMs)
    SuSE Linux Enterprise Server 9 for AMD64

    I used Revision 5.3 of the stream code and compiled with PGI C/C++ for
    Linux v.5.2-4:
       pgcc -O2 -Mvect=sse -Mnontemporal -mp -o ompstream stream_omp.c

    -------------------------------------------------------------
    This system uses 8 bytes per DOUBLE PRECISION word.
    -------------------------------------------------------------
    Array size = 7500000, Offset = 0
    Total memory required = 171.7 MB.
    Each test is run 10 times, but only
    the *best* time for each is used.
    -------------------------------------------------------------
    Number of Threads requested = 2
    Number of Threads requested = 2
    -------------------------------------------------------------
    Your clock granularity/precision appears to be 1 microseconds.
    Each test below will take on the order of 16077 microseconds.
       (= 16077 clock ticks)
    Increase the size of the arrays if this shows that
    you are not getting at least 20 clock ticks per test.
    -------------------------------------------------------------
    WARNING -- The above is only a rough guideline.
    For best results, please be sure you know the
    precision of your system timer.
