CLMA Condor Cluster

What is it?

Condor is a batch-oriented clustering system. Jobs are submitted into a job queue, matched with an available compute node, and run on that node.

Equipment for the patas cluster is partially funded by the Student Technology Fee.

How do I get an account?

If you do not yet have a Computational Linguistics account, fill out our online account request form. You must have a valid UW NetID.

How do I access the cluster?

Open an SSH connection to patas.ling.washington.edu port 22 or dryas.ling.washington.edu port 22. You can also access files on the cluster directly via Samba filesystem shares. See HowToAccessPatas for more information.

How do I use Condor to run my jobs?

Visit the HowToUseCondor Wiki page for a quick introduction. You may also want to view the PDF presentation I wrote for orientation.
