+ | Two of the pods each contain Linux boxes that are configured and managed by Techstaff. They are configured using a template similar to linux.cs.uchicago.edu or student desktops. The linux systems are rebooted each morning at 4:00 AM in order to clean up processes and to make them less desirable platforms for long term execution which would impact performance for the seated user.
