Chapter 1 PBS PRO: GRID COMPUTING AND SCHEDULING ATTRIBUTES

Abstract The PBS Pro software is a full-featured workload management and job schedul-ing system with capabilities that cover the entire Grid computing space: security, information, compute, and data. The security infrastructure includes user au-thentication, 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 cy-cles, 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 param-eters and can provide access to available scheduling information, information about requesting resources, allocation properties, and information about how an allocation execution can be manipulated. 1
