Presenting Condor Version 6.8.7! Condor is developed by the Condor Team at the University of Wisconsin-Madison (UW-Madison), and was first installed as a production system in the UW-Madison Computer Sciences department more than 10 years ago. This Condor pool has since served as a major source of computing cycles to UW faculty and students. For many, it has revolutionized the role computing plays in their research. An increase of one, and sometimes even two, orders of magnitude in the computing throughput of a research organization can have a profound impact on its size, complexity, and scope. Over the years, the Condor Team has established collaborations with scientists from around the world, and it has provided them with access to surplus cycles (one scientist has consumed 100 CPU years!). Today, our department's pool consists of more than 700 desktop Unix workstations and more than 100 Windows 2000 machines. On a typical day, our pool delivers more than 500 CPU days to UW researchers. Additional Condor pools have been established over the years across our campus and the world. Groups of researchers, engineers, and scientists have used Condor to establish compute pools ranging in size from a handful to hundreds of workstations. We hope that Condor will help revolutionize your compute environment as well.
