OpenMPI does not use PATH, at least not by default (or my default).
Node 1:
PATH=/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/elvedin/bin
Node 2:
PATH=/home/elvedin/mpi/ompi/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/bin:/usr/bin
Binary "endian" is in /home/elvedin/mpi/ompi/bin of node 2 (as defined in
PATH) and in /home/elvedin/ of node 1. Running from node 1 with "mpirun -np
2 -machinefile (has node1,node2 in it) endian" -
Failed to find the following executable:
Host: node2
Executable: endian

Someone can correct me if I'm wrong, but I do believe that the
executables don't need to be in the same place on every node, but they
do need to be on every node somewhere in that node's PATH. Certainly,
consistent NFS mounted filespaces is one of the easiest ways to achieve
this.
