GAMESS running on Magny Cours and Istanbul …
I rebuilt them with OpenMPI 1.5 and 1.4.2. Running across 24 cores right now on each.
They are running a test case now that, the previous fastest machine has been a Nehalem 3.2 GHz system.
They are tearing up the track …. The sockets version isn’t as good as the MPI version.
You will see/hear more about this soon, in another white paper.
Needless to say, I am blown away at how fast this is. SMT helps a little, physical cores definitely rock.
More later …
