Better would be Open MPI 1.6.5. Nevertheless the questions are:
- Was Open MPI compiled with SGE integration, i.e. something like:
$ ompi_info | grep grid
MCA ras: gridengine (MCA v2.0, API v2.0, Component v1.6.5)
- Did you request a PE in the submission and how is this PE set up?
- How does the `mpiexec` line in your jobscript look like?
- All nodes can talk to each other directly?

- Regarding this error, maybe you have to set explicitly LD_LIBRARY_PATH with
the path to the dynamic libraries, and export this in your jobscript to the
nodes:
export LD_LIBRARY_PATH=<your_location_of_the_shared_libs>
mpiexec -x LD_LIBRARY_PATH
BTW: The Open MPI is also available on all nodes?
