Your application's process ranks 0 and 2 exited with an exit code 1. You 
might want to look at what's happening with those processes.

mpiexec does an ssh to each node to launch the proxy processes (which in 
turn launch the MPI processes). Typically, for small number of nodes, 
you shouldn't notice a difference unless your machine's ssh is very slow.
