PBS Pro: Grid Computing and Scheduling Attributes

Abstract

The PBS Pro software is a full-featured workload management and job scheduling system with capabilities that cover the entire Grid computing space: security, information, compute, and data. The security infrastructure includes user authentication, access control lists, X.509 certificate support, and cross-site user mapping facilities. Detailed status and usage information is maintained and available both programmatically and via a graphical interface. Compute Grids can be built to support advance reservations, harvest idle desktop compute cycles, and peer schedule work (automatically moving jobs across the room or across the globe). Data management in PBS Pro is handled via automatic stage- in and stage-out of files. The PBS Pro system has numerous site-tunable parameters and can provide access to available scheduling information, information about requesting resources, allocation properties, and information about how an allocation execution can be manipulated.
