Welcome to UGCS!

UGCS is the student-run computing facility of the California Institute of Technology. Historically, UGCS was an educational facility within the Computer Science Department; the name stands for UnderGraduate Computer Science. We are now independent of the CS department, but we continue to provide computing resources to the Institute's undergraduates, graduate students, faculty, and staff. For more information about our past, we have put together a brief history of UGCS.

A "phising" email was just sent to many UGCS users which asks you to reply with a username and password. Do not reply to this message- it is a scam. UGCS sysadmins will never ask you for your password.

We have set /afs/.ugcs/ugcs-admin to be world-readable. You can now look through the various utilites we have written to help automate the cluster administration. Over the next few months, we will be setting up a website to better document the code we have written.

We also have a read-only copy of our svn repository available at http://www.ugcs.caltech.edu/svn, or you can access it at file:///afs/.ugcs/ugcs-admin/svn We're quickly adding our projects to it, so check back often!

Over the next day or two, we will be rebooting our shellservers with a new setup. This will improve their speed and usability, but will result in some downtime in various shellservers. Contact us if you're planning on running and long-term jobs. <math>Insert formula here</math>
