SGEPEWorker() — create a worker running on a Sun GridEngine parallel environment worker node

This creates a new worker process, which runs on the worker node given by nodename as part of a Sun GridEngine (SGE) parallel job. The process is started using 'qrsh -inherit -V', so your SGE setup should be correctly configured to allow this. Generally you would use an SGEPEJob object instead, above, to automatically create worker processes for all SGE nodes.
