STREAM results: Athlon DDR platform result

John:

Please find enclosed STREAM results from executables
built with 4 different Fortran compilers and run on
my brandnew 1200 MHz Athlon DDR platform. I am also
enclosing a .zip file with executables for reference
and in case you would like to distribute executables
for WinNT.

Useable, i.e. STREAM bandwidth on this DDR platform is
barely half of that is reported for the dual channel
RDRAM platforms reported on the STREAM website. The
efficiency of DDR seems to be only about 60%, which
is not entirely unexpected (read/write turnaround
issue).
