Well,
compling with -m64 -xopenmp gives one or two more hundred MB/s
but the variation of the values between different runs can also vary almost
the same amount. So one probably have to run a series of 10 tests or more
and compute
the mean value to see a consistent difference.
Thinking about it theres only one MMU on the Athlon64 even if I use both
cores to throw data at it. And the CPU is in the region of six to four times
faster
than RAM. So using one Core should be enough to drive RAM at top speed.
