Abisko login node has intermittent problems, 2016-10-18 SOLVED

We are experiencing intermittent problems connecting to the Abisko login node. We are searching for the cause.

For now, if the Abisko login node (abisko.hpc2n.umu.se) hangs when you try to login, break the connection and try again.

This system news will be updated with more information when we have it.

 

Update 2016-10-18, 16:34. The network problem has been solved, and there should not be any problems logging in to Abisko any longer.

Matlab 2016b

Matlab 2016b is now the default Matlab version on Abisko. 

Some older version of Matlab is also available. Run 'module avail matlab' when logged in to Abisko to see the current list of available versions.

2016-09-06: Maintenance on the /pfs/nobackup filesystem, Abisko will be stopped.

On September 6th between 08:00 and 17:00 we will perform some necessary software updates of the servers that deliver the /pfs/nobackup file system.

This means that the batch nodes of Abisko must be drained of jobs and the file system unmounted on all nodes, including the login node.

During days leading up to the maintenance window, the system will only accept to run shorter and shorter jobs. It is therefore benficial to submit jobs with short runtimes. 

AFS problems

We are experiencing some problems with one of the AFS-servers. We are working on it and hopefully it should be back online soon. 

As a security measurment we have stopped the batch queue (no new jobs will start). The queue will be restored as soon as the AFS server is back online.

Abisko down due to major power failure in Umeå (power and /pfs/nobackup are now back)

The batch nodes of Abisko is currently down due to a major power failure in Umeå.

The lightning looks to have caused a short-circuit in one of the circuit breakers feeding Abisko.

(To give the electricans a better chance to solve the problem, all power feeds are kept off for the time being, so Abisko is currently completely without power.)

We are currently waiting for electricians to arrive on site.
