I have a simple program that calls MPI_Comm_spawn() to spawn a group of
MPI processes. I found that the hosts running parent and child groups are
overlapped. I ran The job ran though PBS with enough compute nodes
allocated for parents and children to be disjoint.
How do I ensure the hosts running parents and children are not overlapped?
