PBS-derived batch processing server

 The TORQUE server dispatches jobs across physically separated
 machines. It may also be beneficial for single machines to organise
 the sequential execution of multiple jobs.
 .
 Torque stands for "Tera-scale Open-source Resource and QUEue manager".
 It is based on OpenPBS version 2.3.12 and incorporates scalability,
 fault tolerance, and feature extension patches provided by USC, NCSA,
 OSC, the U.S. Dept of Energy, Sandia, PNNL, U of Buffalo, TeraGrid,
 and many other leading edge HPC organizations.
