Downtime Betzy, 6th December 08:00 until 9th December 20:00

There will be a scheduled downtime for Betzy lasting three days starting on Monday 6th December at 08:00. Downtime will last until Thursday 9th, 20:00.

During the downtime we will conduct:

  • Full upgrade of the Lustre filesystem (both servers and clients)
  • Full upgrade of the infiniband firmware
  • Full upgrade of the Mellanox infiniband drivers
  • minor updates to other parts of the system (Slurm, configs, etc)

Please be aware that this does also affect the storage services recently moved from NIRD to Betzy.

We apologize for the inconvenience

[SOLVED] Betzy Downtime 7th June 15:00-20:00

[UPDATE, 2021-06-08 08:00] Betzy is now up and in production again.

[UPDATE] Unfortunately, the downtime is taking longer than anticipated, and will not be finished tonight. We plan on getting Betzy up again at around 08:00 tomorrow morning.

Campusservice at NTNU will conduct maintenance on the High Voltage circuits for Non-redundant power on 7th of June 2021, between 15:00 and 20:00. All compute nodes and login nodes will be shut down during this time, and no jobs will be running during this period. Submitted jobs estimated to run into the downtime reservation will be held in queue.

New compute nodes on Saga

Today, Saga has been extended with 120 new compute nodes, increasing the total number of CPUs on the cluster from 9824 to 16064.

The new nodes have been added to the normal partition. They are identical to the old compute nodes in the partition, except that they have 52 CPU cores instead of 40.

We hope this extension will reduce the wait time for normal jobs on Saga.
