Condor is a popular software tool developed by the University of Wisconsin at Madison Computer Sciences Department. It is a type of batch system that distributes computationally intensive jobs to multiple workstations, thereby creating a grid-style environment and speeding the processing time. Universities and other research institutions can download Condor at no charge, provided they agree to the license terms. The software can be installed on UNIX or Windows machines. Full documentation is given, as are several tutorials and an overview of using Condor with the Globus Toolkit. Various presentations and research publications that discuss Condor are also provided.
