Every day. SGE is no different in it's behaviour with
parallel jobs than any other resource manager. Well, slightly
different... syntatically mostly.

ie, here's a sample job script:

#!/bin/sh
#$ -N myjob
#$ -S /bin/csh
#$ -o job.out
#$ -e job.err
#$ -cwd
#
#$ -pe mpi 8
#
# This is to reformat the hostfile into something MPICH and ScaMPI can use.
#
/home/sge/mpi/startmpi.sh $PE_HOSTFILE

# Launch the job

mpirun -np $NSLOTS -machinefile $TMPDIR/machines ./myjob
