Jon, Almost every cluster job scheduler supports preemption (use it as the google keyword and you will find lots of references...).
Torque has job preemption. I have not used Torque for a while (I used to be an OpenPBS user) so I am not the best person to answer the question for Torque. However, if you google "job preemption"+torque, you should be able to find some useful info. In Grid Engine (and now Open Grid Scheduler) there is Subordinate Queues: http://docs.oracle.com/cd/E19080-01/n1.grid.eng6/817-5677/i998889/index.html Condor is well-known for cycle stealing, and it also offers the checkpoint restart library for Open Grid Scheduler/Grid Engine and other batch systems: http://research.cs.wisc.edu/condor/checkpointing.html http://gridscheduler.sourceforge.net/howto/checkpointing.html (I am sure that you can integrate checkpointing with Torque so you don't need to look for a new batch system to get what you need.)
