OSCER users,


Scheduled maintenance outage Wed June 26 8am-midnight
Central Time

This will affect OSCER's supercomputer only
(NOT OURdisk, NOT OURcloud, NOT OURRstore).

Planned supercomputer maintenance tasks:

(1) Upgrade the Slurm batch scheduler from
Enterprise Linux 7 (EL7) to Enterprise Linux 9 (EL9).

(We'll mostly be using the free variant Rocky 9.)

(2) Upgrade various internal supercomputer virtual machines
from EL7 to EL9.

We expect the work to be finished by midnight Central Time.

After the scheduled maintenance outage, we'll be converting
compute nodes from EL7 to EL9, ramping down the EL7 nodes
and ramping up the EL9 nodes.

As always, we apologize for the inconvenience -- our goal
is to make OSCER resources even better!

If you have any questions or concerns, please email us at:
