A new version with some bugfixes and new features for our batch system, slurm, has been released.

The new version has improvments in how the jobs are scheduled that will enhance utilization of the cluster and we will also change some other configurations for better throughput of jobs.

The upgrade is a major version and will require all jobs to be stopped during the upgrade.

The upgrade should be complete within an hour including testing of the new version on abisko.

Update:
System upgrade finished at 10:20.

Important updates:

Due to scheduled maintenance on the network February 4th between 22:00 and 24:00, access to all HPC2N resources will likely be sporadic and unreliable. Please plan around the time period accordingly.

VASP has now been upgraded to version 5.3.3 on Abisko.

It contains new features like k-point parallization and the x/y/z-restrict patch from NSC.
It will be a fair bit faster for certain types of problems.

The names of the binaries have changed (the old names still remain but will be dropped with the next release).

Please read our updated VASP documentation.

We are currently installing R version 2.15.2 on Abisko. The login node and about half of the compute nodes already have it installed. The other compute nodes will have it installed when currently running jobs finish. 

See /resources/software/r for information about running R at HPC2N.

The /pfs/nobackup file system is currently over 95% full.
That is the limit for starting new jobs on Akka.

Please remove unused files from the file system.

Amber 11 patchlevel 23 with AmberTools 1.5 patchlevel 28 have now been installed on Akka.
It should work a bit better then the previous version and should hopefully be a bit faster.
It has also been made the default.
