2025-07-01 — Upgrade to Rocky Linux 9

During the summer holidays, we have planned an upgrade of our clusters to Rocky Linux 9.
The migration timeline is planned starting July 2025 'till mid-September 2025.

Changes include:

  • new versions of kernel packages, drivers, and system installed user packages
  • update of Slurm to version 25.05 (already finished)
  • only toolchain versions 2023a and above will be available

Users will need to:

  • start using modules from 2023a or above
  • recompiling your code and/or recreating your (virtual) environments
  • check that their code still runs
  • update job scripts (if needed)

During July 2025, there is a free test period for jobs running within the rocky9 reservation (which contains nodes that have already been upgraded).
