[Update, 2022-02-23 12:00]: The maintenance stop has now begun.
Fram supercomputer will be unavailable due to maintenance on the cooling system from February 23rd 12:00 until 24th 20:00
If time allows it we will also upgrade whole or parts/components of the storage system, including file system clients (compute nodes)
We are currently conducting various hardware maintennace on Betzy, including reseating infiniband cables. This may cause instabillity and crashed jobs in other parts of the system not directly connected to the cable being reseated.
We apologize for any inconvenience and lost jobs.
[UPDATE, 2021-12-15 15:00] Betzy is back in prodcution again.
[UPDATE, 2021-12-15 09:00] The downtime has now started.
There will be a short downtime for Betzy next Wednesday 15th from 09:00 until 15:00 to fix remaining hardware issues.
We regret to inform you that the downtime for Betzy has been extended due to a failed hw component not being delivered in time. We hope to have the component delivered during Thursday and subsequently have the system online again in the afternoon of Thursday 9th.
The downtime has started and will continue until wednesday 8th December evening or until upgrades are done.
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:
Please be aware that this does also affect the storage services recently moved from NIRD to Betzy.
We apologize for the inconvenience
Update 08.12.2021 18:00 : Betzy downtime is over, and system is open for users. All planned update is performed .
[Update, 2021-11-24 14:15] Now the NIRD mounts are working again.
[Update, 2021-11-24 13:30] We are back in production and jobs are running som normal again. We are missing the NIRD mounts on two of the login nodes, but are working on fixing that.
[Update, 2021-11-24 12:00] The maintenance has started now.
There will be a short 1 hour downtime for Fram on 24th November, starting at 12:00.
During downtime we will update the firmware on interconnect infiniband switches
[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.
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.
