HTCondor

HTCondor is a workload management system for batch jobs.

Like other full-featured batch systems, HTCondor provides a job queueing
mechanism, scheduling policy, priority scheme, resource monitoring, and
resource management. Users submit their serial jobs to HTCondor and
HTCondor places them into a queue. It chooses when and where to run the jobs
based upon a policy, carefully monitors their progress, and ultimately
informs the user upon completion.

Unlike more traditional batch queueing systems, HTCondor can also effectively
harness wasted CPU power from otherwise idle desktop workstations. HTCondor
does not require a shared file system across machines - if no shared file
system is available, HTCondor can transfer the job's data files on behalf of
the user.
