(It's common to run, say, one process per core for benchmarking.) Running mpirun -tag-output -np 14 -npernode 7 hostname in 16 slots in the following PE (which confines the run to our 8-core nodes) it shows 7 processes on each of 2 nodes. The nodes have exclusive access for MPI jobs, but I don't think that's relevant. pe_name openmpi-8 slots 999 user_lists NONE xuser_lists NONE start_proc_args /bin/true stop_proc_args /bin/true allocation_rule 8 control_slaves TRUE job_is_first_task FALSE urgency_slots min accounting_summary FALSE In this case, you'd get the same effect allocating processes -bynode as using -npernode.
