How to submit multiple jobs in Sun Grid Engine?
It is possible to submit jobs that occupy multiple SGE job slots using the -pe ( p arallel e nvironment) option. This is useful for jobs that require more memory than can be allocated to each core and for jobs that make use of multiple processing threads.
