Open MPI integrates nicely with SLURM in Lenny. All you need to do is to call your job with mpiexec OR mpirun. You do not need to setup anything besides SLURM. If you use sbatch, you could create a file like this: cat >test.sbatch <<EOF #!/bin/sh #SLURM -n 8 mpiexec my_mpi_tool EOF and call it with: $ sbatch test.sbatch SLURM will setup everything for you so mpiexec "knows" how much resources to use.
