system news

Early Saturday morning on October 10th we observed an outage in name resolution (DNS) for HPC2N hosts.

This prevented external and internal access to batch nodes, the website and more.

2020-10-10 11:00
We have restored DNS functionality and HPC2N should once again be reachable from the outside. It may take a little while for the changes to propagate out to internet providers.

Batch jobs that were running may not have run to completion and any queued jobs may have failed on startup.

Abisko Decommissioning

After 9 years and almost 20 million compute jobs, it is time to retire Abisko.

On September 30 2020, Abisko will be closed for public use. From 22 September, no new jobs will be allowed to start. Any remaining jobs in the batch queues of Abisko on September 30 will be deleted.

Amber 18 update 17 with AmberTools 19 update 12  (Amber/18-AmberTools-19-patchlevel-12-17-Python-2.7.16) is now available on Kebnekaise

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.
