The primary focus of this maintenance is to replace the coolant used within the system. During this time, portions of the system (1/3 at a time) will be unavailable for usage until all work is complete. Users may see extended wait times for jobs, but PBS batch jobs will continue to run on the remaining 2/3 of the system.
