Frequently Asked Questions

Q: How do I request an account?

or, for just consulting time:

This work was conducted in part using the resources of the University of Louisville's research computing group.

Q: Is my data backed up?

A: Home directories are backed up. Scratch directories are not. Every user has one home directory and at least one scratch directory. Files in the scratch directories may be periodically deleted when space is an issue, i.e. when more than 90% of the disk is full. You will be given advanced notice before files are deleted so that you can move them off the cluster.

Q: Do I have unlimited storage space?

A: There is a quota of 25 GB for faculty and 10 GB for students on your home directory. There is currently no quota on your scratch directories, although this may change if storage space conflicts arise.

Q: What consulting services do you offer?

A: We offer general consulting on research computing problems. Free open consulting is available for up to 8 hours of consulting, and free extended consulting may be available for up to 160 hours of time. You must apply for extended consulting, and the approval of your application depends on the availability of a consultant with suitable expertise for your research problem. Further information on our consulting services is available here.

Q: Why can't I access the CRC from off campus?

A: The CRC is behind the campus firewall, so users must access it either from an on-campus computer or using the UofL vpn.   When requesting a CRC account, users are automatically given a VPN account.
