I cannot seem to spawn more than a single slave (which is spawned on the
1 slaves are spawned successfully. 0 failed.
master (rank 0, comm 1) of size 2 is running on: node0
slave1 (rank 1, comm 1) of size 2 is running on: node0
2 slaves are spawned successfully. 0 failed.
Error in mpi.intercomm.merge(intercomm, 0, comm) :
MPI_Error_string: process in local group is dead
No doubt the answer is contained in the MPI_Error string, but I'm not
sure how to interpret it.
