I thought this would be relatively straightforward with "--map-by slot:PE=$OMP_NUM_THREADS --bind-to core", but I can't get it to work. I couldn't figure out if it was a bug or just something missing from the documentation, so I created github issue https://github.com/open-mpi/ompi/issues/10071, but that hasn't gotten any response. Does anyone have an example of an mpirun command like, say for 4 16 core nodes running 8 MPI processes with 8 threads each, each bound to 8/16 cores on each node?
