    Hi John,

    This is the 1-cpu AlphaServer GS160-68/1001. The executable image
    used here is the same as in
        http://www.cs.virginia.edu/stream/stream_mail/2000/0024.html

    Best regards

     Double precision appears to have 16 digits of accuracy

     Array size = 4304815
     Offset = 0
     The total memory requirement is 98.53 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 48000 microseconds
        (= 48 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.
