[gmx-users] Parallel run on IBM p575 "poe mpi"

[liu xin]

Hi guys,
just a short question, this is how I run a 8np mpi-mdrun job on my machine:

poe /home/usr/programs/gromacs331mpi/bin/mdrun -v -s 8np.tpr --procs 8
-nodes 8 -task_per_node 1 -single_thread yes -eager_limit 65535
-shared_memory

but it is much slower than the 1np mode, I havent used poe-mpi before, is
there something wrong with my options?

Yours
Xin
