MPI_SPAWN_MULTIPLE usage

Dave17 — Mon, 04 Dec 2023 19:41:30 GMT

If I have two nodes, and mpirun is used such that there are two nodes assigned with one 'mother' process running on each node,

and I want to have 10 spawned processes running on each node: I find that each 'mother' process must call mpi_spawn_multiple with nspawn=20. Is there a chance I could end up with with one node having 15 spawned processes and the other with only 5?
