[gmx-users] MPI runing problem

(a) Make sure that you created your tpr file for 3 nodes, ie 
    'grompp -np 3 ...' 

(b) For my LAM/MPI installation I would say something like

  mpirun C -np 3 mdrun_mpi_d -np 3 -s 3node.tpr ...

  (assuming that the parallel environment is setup for running on 3 nodes)

  I don't know what system you're using but I definitely have to run multi 
  processor jobs through mpirun.
