Gang scheduling combines coordinated context switching with both space-sharing and time-sharing strategies to support execution of parallel applications. Gang scheduling provides good overall system utilization and responsiveness to interactive workloads. This scheduling option is different from backfill scheduling which supports time-sharing and space-sharing scheduling but does not provide coordinated context switching. It is also different from EASY scheduling (a common instance of an external scheduler) which only supports space-sharing. For more information see Using Gang scheduling.
