It can be used to manage workload on a dedicated [[Computer cluster|cluster of computers]], or to farm out work to idle desktop computers{{spaced ndash}}so-called [[CPU scavenging|cycle scavenging]].  HTCondor runs on [[Linux]], [[Unix]], [[Mac OS X]], [[FreeBSD]], and [[Microsoft Windows]] [[operating system]]s.  HTCondor can integrate both dedicated resources (rack-mounted clusters) and non-dedicated desktop machines (cycle scavenging) into one computing environment.

HTCondor is developed by the HTCondor team at the [[University of Wisconsin–Madison]] and is freely available for use.

While HTCondor makes use of unused computing time, leaving computers turned on for use with HTCondor will increase energy consumption and associated costs. Starting from version 7.1.1, HTCondor can hibernate and wake machines based on user-specified policies, a feature previously available only via third-party software.
