I just made some benchmarks on a Opteron 240 (1.4 GHz) node running with
Suse/United Linux Enterprise edition.
I have sucessfully compiled mpich-1.2.4 in 64 bit without any problems
(./configure -device=ch_p4 -commtype=shared). The default compiler is
the gcc-3.2.2 (maybe a Suse patch) and is set to 64Bit, the Portland
(5.0beta) compiler didn't worked at all !
I tried our CFD-code (TAU) to run 3 aerodynamik configurations on this
machine with both CPUs and the results are better then estimated.
We achieved in full multigrid (5 cycles, 1 equation turbulence model) a
efficiency of about 97%, 92% and 101 % for the second CPU.
Those results are much better as the results we get on the Intel Xeons
