You shouldn't need anything special -- I don't. (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.
In this case, you'd get the same effect allocating processes -bynode as
