Subject: HPC Cluster maintenance, Monday August 18
Greetings CHTC users, 

This email is for users of our HPC Cluster (logging into spark-login.chtc.wisc.edu). 

The HPC cluster maintenance scheduled in July requires a follow up, so there will be another maintenance period next Monday, August 18.

The HPC cluster will be unavailable starting early in the morning on August 18. No jobs will run or be accepted during this time. Queued jobs should continue once the maintenance downtime has completed. Jobs submitted with a runtime that intersects with the maintenance window will not start, with the reason "ReqNodeNotAvail, Reserved for maintenance".
For the most up-to-date information, including when the system is back online, please refer to the system Status Page:
We strongly encourage all users to subscribe to or check this page regularly for current system status and announcements. It's the best way to stay informed about system availability.
Best, 
Your CHTC Team
