[gmx-users] Gromacs on Xserver G5 /MPI

[abelius]

Dear All,

Does anyone have experience with running gromacs on a apple Xserve G5? A
simple install works fine but when I try to run mdrun on 2 processors
using mpi I get one process running at +/- 70% CPU and one remains at 0%
CPU.

Does this sound familiar to anyone?


System:
	Xserve G5
	OsX 10.3.9
	Darwin Kernel Version 7.9.0

Commmand:
	mpirun -np 2 <path>/mdrun_mpi -s topol_md.tpr -o traj_md.trr -c md.pdb
-e ener_md.edr -np 2





Thnx in advance,
Abel
