Condor Condor is a software package for executing long running "batch" type jobs on workstations which would otherwise be idle. Major features of Condor are automatic location and allocation of idle machines, and checkpointing and migration of processes. All of these features are achieved without any modifications to the UNIX kernel whatsoever. Also, users of Condor do not need to change their source programs to run with Condor, although such programs must be specially linked. The features of Condor for both users and worksta- tion owners along with the limitations on the kinds of jobs which may be executed by Condor are described. The mechan- isms behind our implementations of checkpointing and process migration are discussed in detail. Finally, the software which detects idle machines and allocates those machines to Condor users is described along with the techniques used to configure that software to meet the demands of a particular computing site or workstation owner.
