The Statistics Cluster is equipped with a powerful job queuing system called [http://research.cs.wisc.edu/htcondor/ Condor]. This framework provides efficient use of resources by matching user needs to the available resources by taking into account both the priorities for the hardware and the preferences of the job. Matching resource requests to resource offers is accomplished through the <b><i>ClassAds</i></b> mechanism. Each virtual machine publishes its parameters as a kind of <u>class</u>ified <u>ad</u>vertisement to attract jobs. A job submitted to Condor for scheduling may list its requirements and preferences. Jobs are submitted with the <b><i>condor_submit</i></b> command with a job description file passed as an argument. A simple description file goes as follows:
