Just a heads up to anyone who uses MVAPICH2 with srun. The 2.1 docs for MVAPICH2 have new configure flag values since 2.1 supports PMI-2 with SLURM. If you build MVAPICH2 2.1 with SLURM support and then use srun with "--mpi=none" I've found things don't go well. The steps to use srun with MVAPICH2 2.1 appear to be identical to that of OpenMPI. We have set MpiDefault=pmi2 which will not "just work" for MVAPICH2 2.1.
