OpenMPI

To run batch jobs using the Platform MPI, you need to use just mpirun wrapping your program.

$ module load gcc/4.8.1
$ module load mpi/openmpi/1.6.5/gcc_4.8.1
$ mpicc program.c -o program
$ bsub ... mpirun ./program

On big runs some tuning options for the mpirun might be necessary (as with all MPIs). E.g. for NAMD2 we used:

mpirun  -bind-to-core -mca btl openib,sm,self namd2 input
