    Hi John,

    Finally, for today, here is the 1-CPU AlphaServer ES40 6/833. This
    run used the previously approved version from
    http://www.cs.virginia.edu/stream/stream_mail/2000/0023.html

    Yes, I know it's a little odd that my colleague used an OpenMP version
    on a single-CPU test, but I don't think that should invalidate the
    result. I hope you agree.

    Thanks
        -john

     Double precision appears to have 16 digits of accuracy
     Assuming 8 bytes per DOUBLE PRECISION word

     Array size = 4008399
     Offset = 0
     The total memory requirement is 91.74 MB
     You are running each test 10 times
     The *best* time for each test is used
     ----------------------------------------------------
     Your clock granularity/precision appears to be 900 microseconds
     The tests below will each take a time on the order
     of 41000 microseconds
        (= 46 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.
