Current Projects

This is the list we will work from in addition to service requests.

Some important procedural pages:

  • Web logins
  • Password management
  • Docker and WebODM on Bronte
  • Fix shinken server access
  • Backup in Lilly basement
  • Backup on all machines - includes backup.cs.e.e (indiana?)
  • Post shutdown
  • power map additions and updates - update the power map and get as much of our power data (how much we use, how much we could theoretically be using, etc.) all together
  • clean up system variables, e.g. verifying that all our systems have Python 2 as a default not Python 3, using Charlie’s earlier email about cexecs as a starting point (in your inbox or the mailing list, search for “A bit of cleaning on the cluster side”)
