At around 19:20 today (30/1), the power to the clusters was lost. That means both kebnekaise and abisko is not running any jobs. All running jobs has has stopped. We are working on getting back the power and the cluster up. This message will be updates has we know more.

Login to the kebnekaise access nodes will stall until the kebnekaise cluster is back up. Abisko login node should work.

*Update* 2019-01-30 22:40: Abisko should be up and running again. Kebnekaise has some problems with /pfs and is still down. Probably will not be fixed until tomorrow.

We have suffered a power failure at HPC2N due to cooling failure.

The power failure covers both Kebnekaise and Abisko, thus all jobs that where running have failed and no new jobs can start.

This may also result in problems login in to Kebnekaise if your login shell tries to access the /pfs/nobackup file system or load modules.

We have stopped all queues and will asses the situation as soon as we can.


*UPDATE 20181022 09:00*

The problem with the cooling system should be fixed according to Akademiska Hus.

GPU outage on Kebnekaise (resolved)

The GPU nodes of Kebnekaise are temporarily unavailable since the evening of Monday 2018-09-24. Jobs that started after that may have failed with messages about mismatched driver versions and may report missing GPUs.

We are addressing the problem, while work progresses nodes will be unavailable and the queue may report that jobs are blocked due to resources. We will update this news entry when this is resolved.

Kebnekaise running jobs failed 2018-09-05 18:44

Kebnekaise cluster nodes had unexpected problems during the
maintenance of a internal service related to them.

This caused disk access timeouts, which in turn terminated
jobs running on the nodes.

The problem have been solved and the cluster is working
normally again.

We are sorry about the problems this have caused.
