Portable Batch System (or simply PBS) is the name of computer software that performs job scheduling. Its primary task is to allocate computational tasks, i.e., batch jobs, among the available computing resources. It is often used in conjunction with UNIX cluster environments. Several spin-offs of this software have resulted in it having various names. However, the overall architecture and command-line interface remain essentially the same. PBS is one of the job scheduler mechanisms supported by GRAM (Grid Resource Allocation Manager), a component of the Globus Toolkit.
History and versions
PBS was originally developed by MRJ for NASA in the early to mid-1990s. MRJ was taken over by Veridian, which was later taken over by Altair Engineering, which currently distributes PBS Pro commercially. The following versions of Portable Batch System are currently available:
- OpenPBS — unsupported original open source version
- TORQUE — a fork of OpenPBS 2.3.12.[1] Paid support available through Cluster Resources.
- PBS Professional (PBS Pro) — a version maintained and sold commercially by Altair Engineering
