  • Slurm will be upgraded

  • File system clients (Spectrum Scale, Lustre and BeeGFS) will be updated

  • Singularity will be replaced with its successor Apptainer

  • Additional software updates will be announced at a later stage

Maintenance 12.07. - 16.07.2021

From July 12th 9:00 am until July 16th noon, no compute nodes will be available on HoreKa and HAICORE, so no jobs will run. Additionally, individual login nodes will be unavailable for some time during this interval, which will also affect the Jupyter and CI services.
