    The system used was:
       IBM eServer pSeries 650 Model 6M2. 8 CPU. 1450 Mhz.
       SUSE's SLES 8 for pSeries GA'ed product w/2.4.19 UL 1 64-bit kernel.

    The "un-tuned" results were:
          Copy: 6108
          Scale: 5936
          Add: 7429
          Triad: 7588

    These results were consistent with runs done on AIX on the same model
    hardware.

    Number of Threads = 8
    ----------------------------------------------
     Double precision appears to have 16 digits of accuracy
     Assuming 8 bytes per DOUBLE PRECISION word
    ----------------------------------------------
     Array size = 66060288
     Offset = 96
     The total memory requirement is 1512 MB
     You are running each test 100 times
     The *best* time for each test is used
     ----------------------------------------------------
     Your clock granularity/precision appears to be 1 microseconds
     The tests below will each take a time on the order
     of 115993 microseconds
        (= 115993 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.
