UTHPC - Notice history

Dear User,

We inform you that the University of Tartu HPC cluster Rocket, its file systems, and the cluster cooling system will undergo scheduled maintenance (will not be available) during the period of January 12-18, 2026.

The purpose of the maintenance is to:

• increase the cluster's CPU and GPU capacity;

• expand the availability of GPU resources for cloud services and Kubernetes containers;

• enhance the cluster room cooling system to support the increasing computing power.

During the maintenance period, the following services will not be available:

• UTHPC cluster Rocket;

• file systems /gpfs/space and /gpfs/helios;

• OpenOndemand services

• Galaxy (galaxy.hpc.ut.ee)

The maintenance will not affect the UTHPC cloud service (virtual machines), Kubernetes containers, or websites, except in cases where they use NFS or Samba network drives (mounted file systems). In the near future, we will contact the master users of instances connected to NFS or Samba file systems.

The cluster, along with the file systems, will be available again for computations starting from January 19, 2026.

If you have any questions or concerns about whether the January maintenance may affect your work, please consult us at support@hpc.ut.ee

Thank you for your understanding!

Best regards, 

UTHPC team
