MPI enabled programs are launched through sge with a batch file similar to this one (modify for your specific software):

#!/bin/sh

# Batch file for launching mpi tasks. Submit tasks with: qsub <name of this file>

# Transfer current environment to job
#$ -V

# Ask for 4 parallel slots (currently at most 8)
#$ -pe openmpi 4

# Request run time (modify this!! and memory per task, total memory usage will be number of tasks times this request)
#$ -l h_rt=1:0:0,h_vmem=1G


# Launch the program with mpirun
mpirun <my_program> <options_to_my_program>
