Milgram Scheduled Maintenance
Dear Milgram Users,
We write to remind you that scheduled maintenance will be performed on the Milgram cluster starting on Tuesday, February 6, 2024, at 8:00 am. Maintenance is expected to be completed by the end of day, Thursday, February 8, 2024.
During the maintenance, logins to the cluster will be disabled. We ask that you save your work, close interactive applications, and logoff the system prior to the start of the maintenance. An email notification will be sent when the maintenance has been completed, and the cluster is available.
Upgrade to Red Hat 8
Milgram’s current operating system, Red Hat Enterprise Linux (RHEL) 7, will be officially end-of-life in 2024 and will no longer be supported with security patches by the developer. Therefore, Milgram will be upgraded to RHEL 8 during this maintenance.
Changes to Interactive Partitions and Jobs
We are making two changes to interactive jobs during the upcoming maintenance.
The ‘interactive’ and ‘psych_interactive partitions will be renamed to ‘devel’ and ‘psych_devel’, respectively, to bring Milgram in alignment with the other clusters. This change has been made on other clusters in recognition that interactive-style jobs (such as OnDemand and ‘salloc’ jobs) are commonly run outside of the ‘interactive’ partition. Please adjust your workflows accordingly after the maintenance.
Additionally, all users will be limited to 4 interactive app instances (of any type) at one time. Additional instances will be rejected until you delete older open instances. For OnDemand jobs, closing the window does not terminate the interactive app job. To terminate the job, click the “Delete” button in your “My Interactive Apps” page in the web portal.

Sincerely,
Paul Gluhosky
