From “man mpirun” - note that not specifying “slots=N” in a hostfile defaults to slots=#cores on that node (as it states in the text): Specifying Host Nodes Host nodes can be identified on the mpirun command line with the -host option or in a hostfile. For example,

I gather you are using OMPI 2.x, yes? And you configured it --with-pmi=, then moved the executables/libs to your workstation? I suppose I could state the obvious and say “don’t do that - just rebuild it”, and I fear that (after checking the 2.x code) you really have no choice. OMPI v3.0 will

is it possible to disable slurm/munge/psm/pmi(x) from the mpirun command line or (better) using environment variables? i'd like to use the installed version of openmpi i have on a workstation, but it's linked with slurm from one of my clusters. mpi/slurm work just fine on the cluster, but when i
