CS Ionic Cluster Downtime, Thursday, October 19, 2023, 7:30-9:30
Who is affected:
All users of the CS Department Beowulf high performance computing cluster,
known as ionic.
What is happening:
CS Staff will upgrade the cluster management and job scheduling system
Slurm and its database. No reboot will be necessary; thus, we expect to
finish the upgrade earlier than this window. However, the wide time frame
acknowledges the uncertainties involved.
Why is it happening:
The upgrade is necessary to patch against an urgent security bug.
We will post updates to the status page: www.csstaff.org
as necessary.
If this downtime will cause you undue hardship, please contact
csstaff@cs.princeton.edu immediately, so we can discuss options to reduce
any negative impact. Your patience is appreciated.
Sincerely,
CS Staff
