can you please check, whether your Open MPI was built with support for SGE
properly:
$ ompi_info | grep grid
MCA ras: gridengine (MCA v2.0, API v2.0, Component v1.4.3)
A simple `hostname` should work. You installed this version of Open MPI on all
machines? What does your PE definition look like: "control_slaves TRUE" is set?
