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.

The combination to our door is available if you are on the Caltech network.
