Accounts

Eligibility

Employees, students, and external collaborators sponsored by a faculty member. ucdenver.edu or cuanschutz.edu login with VPN access required.

How to get an account

Please

  • Read the Terms and Conditions first.
  • Use this form to request an account. For a permanent account, the form should be filled by a faculty member (the PI of the project) and list users in their group, such as students, postdocs, or external collaborators. Compliance needs the legal "yes" clicks from a faculty member. External collaborators need an affiliate appointment called "POI" with remote access first, talk to your department HR contact. Check "security" on their affiliate form to request VPN.

The form will ask for the CU Denver email addresses for all accounts to be created, and

  • A brief description of the project. Just few words are enough.
  • Funding source, if any,
  • Affirmation of the Terms of Use,

This is needed for reporting to the funding agency (annual reports, quad charts, PI meetings, etc.)

We really need the "yes" clicks for all those terms and conditions!

Workshop participants can also get a temporary account by filling the form with "Workshop" in the project box.

Resources and Allocations

To encourage early use, the following is in effect for an initial period - we want you to work here! A more formal allocation process will start when needed.

Storage

Users are responsible for maintaining copies of all their important files elsewhere. Files can be lost even with backups.

  • Home directories – Home directories are /home/username. Please keep the home directories small, up to 25GB. Backed up occasionally. Home directories over 25GB may not be backed up.
  • Project storage - Not backed up. All users have project directory. These are /data001/projects/username or /storage/department/projects/username. We can make project directories which can be shared between a group of users. Please keep project directories to 25OGB.
  • Scratch - no limit, not backed up, older files may be deleted automatically. Please make your own subdirectories in /scratch. In future, files will be deleted automatically when the filesystem fills up.

Use the command du -sh in a directory to see how much storage space you are using, and df to monitor the overall storage space. The space used can be different from the size of your files as reported by ls -l, particularly for very large files.

Running Jobs

  • Users are set up with the default 500 concurrent CPU cores and 3 concurrent GPUs limit. Higher CPU cores limit is possible upon request. Your cores limit may be increased quietly temporarily when your jobs are waiting and there are enough cores available for everyone.
  • Run time of jobs on math-alderaan nodes is maximum 7 days. This is a hard limit.
  • The total usage of CPU and GPU hours is unlimited.

Old Files

  • After a period of user inactivity, user files can be deleted after a notification to the user's university email address and a grace period.
  • Older files in scratch space can be deleted also for active users.
