FAS Research Computing - Status Page

Monthly maintenance will take place on November 3rd. Additionally, MGHPCC will be performing power upgrades on the even side of Row 8A where much of our computer resides. A further upgrade will take place Dec. 8th on the odd side.

A list of the affected partitions is provided at the bottom of this notice. The nodes in those partitions will be drained prior to the work and will be powered down. Once the work is completed, those nodes will be returned to service. Current estimate is a 12 hour window. We will adjust as we know more.

MAINTENANCE TASKS
Cannon cluster will be paused during this maintenance?: PARTIAL OUTAGE/YES
FASSE cluster will be paused during this maintenance?: PARTIAL OUTAGE/YES

• Power work on Row 8A Even

  • Audience: Users of the partitions listed below

  • Impact: These nodes and partitions will be fully or partially down all day

• Slurm upgrade to 25.05.4

  • Audience: All cluster users

  • Impact: Jobs will be paused during maintenance

• Block repo.anaconda.com cluster wide

  • Audience: Anyone attempting to use repo.anaconda.com

  • Impact: This change should not impact your Python workflow on the cluster. But if it does, consider using the open-source channel, conda-forge, through Miniforge distribution to install Python packages. This can be done by following our instructions on https://docs.rc.fas.harvard.edu/kb/python-package-installation/

• Change Slurm User to Local User

  • Audience: All cluster users

  • Impact: Behind the scenes. No impact to users

• Login node reboots (morning)

  • Audience: Anyone logged into a FASRC Cannon or FASSE login node

  • Impact: All login nodes will rebooted during this maintenance window

• Netscratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ )

  • Audience: Cluster users

  • Impact: Files older than 90 days will be removed. Please note that retention cleanup can and does run at any time, not just during the maintenance window.
