Using Condor(redirected from Computing.UsingCondor) Condor at UJ
A collection of misc stuff about using CondorCondor is a "Cycle Scavenger" - it finds idle workstations on the network, and uses them to process batch jobs. Very nice to run heavy jobs, taking advantage of non-dedicated resources - it's like getting a cluster out of a bunch of PCs. We also use it to manage the cluster, with dedicated machines that start up on demand to process jobs. Remember that a user coming back to his PC will interrupt your calculation at any time; because of this, it's best to avoid too long jobs. Something like 30 minutes to 2 hours is quite ok.
