RELION 3.1.0 is now available on Kebnekaise.

We need to make a short maintenance on the paralle file system servers, 2020-06-23 08:00.

The operation should take approx 15-30 minutes.

There will be no jobs running during the maintenance since the operation is somewhat disruptive to the file systems.

Only jobs with a runtime that ends before the maintenance will be allowed to start.

Jobs with short runtimes will have a high likelyhood of getting run in the upcoming gaps.

You will be unable to login during that time since we are upgrading the firmware

We lost power around 09:40 today due to a University wide power failure.

This means that login is not possible at the moment.

We will update this with new info when we get any updates.

*UPDATE 20200527 11:25*

Power is now back and we are powering up the systems

*UPDATE 20200527 11:50*

Login nodes are now open again, cluster batch nodes are coming up soon and jobs will start running before 13:00

We are currently having problems with the HOME directory file server.

We hope to have it fixed before 09:00

*UPDATE 20200526 08:25*

Problem solved.

Due to ongoing attacks towards various HPC centers in Europe we have decided to disable new logins until Thursday morning when we hopefully will have more information.

*UPDATE 20200514 13:07 Logins are now enabled again.*

Monday 2020-05-11 we will have a maintenance on the cooling system.

This affects both clusters causing them to be offline.

The maintenance window is between 06:00 and 17:00 on Monday 2020-05-11

During the time leasding up to the downtime only shorter (and shorter) jobs can run.

*UPDATE 2020-05-11 17:35*

An unexpected problem is causing a delay in getting the clusters up and running again.

We're working as fast as we can to fix the problem.

Due to power maintenance in the MIT building, there will be two outages that affects HPC2N's systems, one on 20 April 2020 and one on 21 April 2020.

For this reason, the batch systems on both Abisko and Kebnekaise will be down and no jobs will run.

Downtimes for the clusters

Monday, 2020-04-20, 6:30-12:00

Tuesday, 2020-04-21, 11:30-17:00

In the days before the maintenance, only jobs that have a runtime which is short enough to finish before the start of the maintenance will run.

The batch queues on the clusters are suspended while we perform some troubleshooting. Jobs already running should continue to run but no new jobs will start until this concludes.

There will be a two day maintenance on the cooling system and power feed 2019-10-16 - 17 that affects both Kebnekaise and Abisko.

The maintenance window starts at 2019-10-16 04:00 and ends 2019-10-17 18:00

The clusters will be down during that period and no jobs will be running.

During the days leading up to the maintenance only jobs with a short enough runtime to finish before the maintenance starts will be allowed to run.

So, if you have jobs that can use a shorter runtime it is advisable to submit them during the week(s) before the maintenance window.
