The HPC cluster systems use the Sun Grid Engine (SGE) queue scheduler system. The feature of a queue scheduler system that users interact with the most is that of job submission. The manual pages for SGE are very good and should be referred to for details. For this particular topic the qsub manual page is the authoritative source.

This document provides a brief introduction to the most common options that might be used to submit jobs to the SGE system. It will focus on single processor jobs as that is the most basic case, but not necessarily the most common. Details on submission of parallel jobs is covered in Advanced Job Submission.
