I just want to confirm the default behaviors we want for OMPI v5. This is what we have currently set:
* if the user specifies nothing:
if np <=2: map-by core, rank-by core, bind-to core
if np > 2: map-by socket, rank-by core, bind-to socket
* if the user only specifies map-by:
rank-by and bind-to adopt the same policy - e.g., map-by numa would
result in rank-by numa, bind-to numa
If anyone wants something else, NOW is the time to speak up!
