Yeah, hi, I built a module to do that, and we used it in production for about two years. Unfortunately, I couldn't get the approvals to post the module on CPAN. It was a nice module too, because it also managed to spawn jobs locally if the grid engine wasn't available.

You could write you own, though -- mine just did some intelligent scraping of the output from the qstat command and used qsub to submit jobs and captue the job ID that was output.
