System update rollout on Hydra and Anansi

We are updating the operating system on Hydra and Anansi with the latest security and bug fixes. The rollout will start on Saturday July 18th at 03:00 CEST and will be gradually carried out in the coming days. This operation has a minimal impact on our users: compute capacity will be slightly lower during the update, but there will be no downtime of the clusters and all job queues will remain operational.

We will also update the login nodes of Hydra and Anansi during this window. Access to the clusters will be briefly unavailable to users during the night of Saturday on Sunday, and all user sessions on the login nodes will be disconnected, but running jobs will not be impacted.

These operations are part of the regular updates to keep VUB-HPC infrastructure modern and up to current standards. Please contact us at VUB-HPC Support if you have any comments or questions about these changes.
