HTCondor is a software system that creates a High-Throughput Computing (HTC) environment. It effectively uses the computing power of machines connected over a network, be they a single cluster, a set of clusters on a campus, cloud resources either standalone or temporarily joined to a local cluster, or international grids.

A user submits jobs to HTCondor. HTCondor finds available machines and begins running the jobs there. HTCondor has the capability to detect that a machine running a job is no longer available (perhaps the machine crashed, or maybe it prefers to run another job).
