As you indicated, this seems to work for you. Good.

Can you repeat this and run a non-MPI executable such as "hostname"? I want to take MPI out of the equation and just test the launching system.

Can you also verify that you are correctly matching your OMPI installations on all nodes? I.e., that you've got Open MPI installed in the same location on all nodes in your cluster, and your PATH and LD_LIBRARY_PATH are pointing to the version of Open MPI that you intend to use.
