Maui Cluster Scheduler, the precursor to Moab Cluster Suite, is an open source job scheduler for clusters and supercomputers. It is an optimized, configurable tool capable of supporting an array of scheduling policies, dynamic priorities, extensive reservations, and fairshare capabilities. It is currently in use at hundreds of government, academic, and commercial sites throughout the world. All of the capabilities found in Maui are also found in Moab, while Moab has added features including virtual private clusters, basic trigger support, graphical administration tools, and a Web-based user portal.
