-CSIL is located in Crerar Library and is composed of 4 pods of computers along with additional Macs external to the pods and a staff of student aids known as “tutors”.  The pods have collapsing walls that allow them to be reconfigured into larger spaces.  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.  The other two pods each contain 20 Macs which are configured and maintained by CSIL tutors. +CSIL is located in Crerar Library and is composed of 4 pods of computers along with additional Macs external to the pods and a staff of student aids known as “tutors”.
