[OMPI users] mixed OpenMP/MPI

[Bernstein, Noam CIV USN NRL (6393) Washington DC (USA) via users]

Hi - I'm trying to run multi-node mixed OpenMP/MPI with each MPI task bound to 
a set of cores.  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?
