Typically on our cluster we use:
srun --mpi=pmi2To launch MPI applications as we have task affinity turned on and we want to ensure that the binding works properly (if we just invoke mpirun it doesn't bind properly). One of our users wishes to pass in more options to srun to tune MPI (specifically OpenMPI 1.10.2) such as to standard MPI options:
mpirun -mca btl self,openibMy question is how do I get slurm to pass these options through when it invokes MPI.
