The program binaries, documentation, and source code may all be found on the Condor project's Web site at www.cs.wisc.edu/condor.

The Condor Public License permits installation, use, reproduction, display, modification and redistribution of Condor, with or without modification, in source and binary forms.

This chapter introduces all aspects of Condor, from its ability to satisfy the needs and desires of both submitters and resource owners, to the management of Condor on clusters. Following an overview of Condor and Condor's ClassAd mechanism is a description of Condor from the user's perspective. The architecture of the software is presented along with overviews of installation and management. The chapter ends with configuration scenarios specific to clusters.
