Any hints on what to look for to get the second machine to behave without
duplicate independent processes?
"mpirun -np 2 ..."
Provides as expected:
"Using MPI version 2.1, 2 processes
While on another similar machine:
"Using MPI version 2.2, 1 processes
Using MPI version 2.2, 1 processes
mpirun (Open MPI) 1.4
I looked in the FAQ and searched the list but did not find it yet. When I
worked with MPICH2 I also had this happen from time to time. I can provide
additional information should it not be as common here.
