Known issues

[Tue 13 Sept 2022] Unscheduled downtime HPC-UGent Tier-2 login nodes

  • [16:00] Problem resolved, login nodes are available again.
  • [15:25] Due to a network issue login nodes became unavailable.

Planned maintenance

Scheduled maintenance work to Tier1 Hortense (24-28 October 2022)

Downtime of the entire Tier1 Hortense system is needed:

  • start 24/10 06h00
  • end 28/10 17h00

Repairs will be done to the existing nodes and preparatory work is planned to the datacenter and hardware in view of the second phase of Tier1.

Impacted: all login nodes, all compute nodes and the shared SCRATCH filesystem will be offline.


  • [May 2022] All HPC-UGent login nodes and Tier-2 clusters have been migrated to the Red Hat Enterprise Linux 8 operating system.
  • [Wed 9 June 2021] New job command wrappers
    We switched to new job command wrappers for all HPC-UGent Tier-2 clusters.
    This switch should be transparant: you don't need to change your workflow or job scripts.
  • [Wed 27 May 2020] All SSH public keys uploaded before 20 May 2020 have been revoked.
