TORQUE Resource Manager
TORQUE, an open source resource manager based on the original *PBS project, now features high availability (or redundant) mode which ensures clusters will continue to run even if the host server fails. Two host servers will boot at the same time but only one server does a complete boot. The backup server partially boots, and then regularly cycles between a sleep mode and checking the main host server for system failures every second. If the backup server detects the head node has gone down it will immediately replace the failed node.
