PBS stands for ``Portable Batch System''. It is a suite of programs for submitting jobs to distributed computational resources, e.g., to clusters such as our AVIDD. There are many versions of PBS floating around. For example, there is OpenPBS developed originally for NASA and ``Scalable OpenPBS'' distributed by Superclusters.org, a site that is run by Cluster Resources, a company in Utah. Then there is ``Professional PBS Pro'' distributed by OpenPBS.org, which is one of many shopping windows of Altair Engineering, a company located in Michigan.
The version installed on AVIDD at present is ``Scalable OpenPBS'' with the Maui scheduler.
In the following sections you will learn how to make sense of these manuals and how to use PBS on the AVIDD cluster.
