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.
