I have a tool I wrote for configuring GridEngine PEs for this sort of purpose: https://github.com/brlindblom/gepetools
It provides the requestable complex resources pcpus # default is fill_up... can change to round-robin if desired ppn & nodes # allows processer & node requests for requesting parallel resources. It maps PEs to defined host groups. We use this since our host groups tend to map to different interconnect fabrics. With the jsv in place, you simply need to submit a job with -l nodes=x,ppn=y in order to get the type of allocation you are looking for. Then, its up to your MPI runtime and openmp environment variables to figure out how to distribute the processes. Not sure if it would be useful for you.
