We’ve recently revamped our website. Although it looks very much the same when you visit it from your desktop computer, one major change we’ve made is how the website is formatted for mobile devices. Mobile computing has been on the rise the past couple of years, so more and more of our users visit our site on their mobile devices.

Environment Modules

What are Environment Modules?

The environment modules are a system that allows you to quickly and easily modify your shell environment to access different software packages. Research Computing offers a large (and growing) number of software packages to users, and each package may contain several tools, manual pages and libraries, or it may require special setup to work properly. Some software packages come in several versions or flavors, many of which conflict with each other. Modules allows you to tailor your shell to access exactly the packages you need by setting up the relevant environment variables for you, and automatically avoiding many possible conflicts between packages. read more »

How do I Submit a Job?

Posted on Wednesday, May 7, 2008 at 2:53 pm

Most of the nodes in the URC cluster are accessed using the Condor job scheduling system which can accept both serial and parallel batch jobs. However, URC is transitioning away from Condor towards using Torque for job scheduling, so we would encourage you to use start using Torque instead of Condor. We have more information about submitting jobs to Torque on the URC cluster. read more »
