Yes, the processes are not spawned by MPI and they are not spawned by something like Slurm/PBS.
How does MPI get to know what processes running in what nodes in a general sense? Do we need to write some plugin so that it can figure out this information? I guess this must be the way it is supporting Slurm/PBS etc. Thanks, Supun..
