    Hi,

    Here you are another result for your tables.

    This machine has an ABIT KT7A motherboard with a 850 MHz Athlon overclocked to
    910 MHz. The memory is 768MB of 133MHZ.

    I have compiled the STREAM benchmark with GCC 3.0:
    gcc-3.0 -O -fstrict-aliasing -mcpu=pentiumpro -march=pentiumpro -static -s
    -fomit-frame-pointer stream_d.c second_wall.c -o stream_d-3.0 -lm

    Here the results....

    -------------------------------------------------------------
    This system uses 8 bytes per DOUBLE PRECISION word.
    -------------------------------------------------------------
    Array size = 1000000, Offset = 0
    Total memory required = 22.9 MB.
    Each test is run 10 times, but only
    the *best* time for each is used.
    -------------------------------------------------------------
    Your clock granularity/precision appears to be 1 microseconds.
    Each test below will take on the order of 27887 microseconds.
       (= 27887 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.
