    Hi John,

       This is the AlphaServer GS160-68/1001 with 16 CPUs. It uses the
    same binary as was used for
       http://www.cs.virginia.edu/stream/stream_mail/2000/0013.html

    ----------------------------------------------
     Double precision appears to have 16 digits of accuracy
     Assuming 8 bytes per DOUBLE PRECISION word
    ----------------------------------------------
     Array size = 120000672
     Offset = 0
     The total memory requirement is 2746.60 MB
     You are running each test 10 times
     The *best* time for each test is used
     ----------------------------------------------------
     Your clock granularity/precision appears to be 1000 microseconds
     The tests below will each take a time on the order
     of 111000 microseconds
        (= 111 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.
