TORQUE is an open source resource manager providing control over batch jobs and distributed compute nodes. It is a community effort based on the original *PBS project and, with more than 1,200 patches, has incorporated significant advances in the areas of scalability, fault tolerance, and feature extensions contributed by NCSA, OSC, USC , the U.S. Dept of Energy, Sandia, PNNL, U of Buffalo, TeraGrid, and many other leading edge HPC organizations. This version may be freely modified and redistributed subject to the constraints of the included license.

TORQUE can integrate with Moab Workload Manager to improve overall utilization, scheduling and administration on a cluster. Customers who purchase Moab Workload Manager also receive free support for TORQUE.
