How to get an account for UCD users

As of May 2016, Janus is going off-maintenance and is no longer accepting new users. Janus is being decommissioned and replaced by Summit.
This page is kept for archival purposes only.
  • Go to https://www.rc.colorado.edu/accountrequest to submit a request, using your ucdenver.edu email address.
  • You will be contacted by email with further instructions and to provide the name of the project, the funding information (if externally funded), and email address of the project leader. If you are a new user on an existing project, the project name and leader are sufficient.
  • Project leaders must create a page for their project following the Janus cluster project template. Please keep the project wiki page up to date.
  • All accounts must belong to a project in list of Janus cluster projects. Project leaders are responsible for the computer use and timely reporting on the project's results.
  • The project leader is responsible for complying with export controls. In particular, the computer may be used only for fundamental research.
  • For now, all UCD users must be UCD employees or students. There is no charge for using the supercomputer and no allocation process yet.
