Dione reboot partially completed, compute nodes 37 & 38 not yet updated. Avoid using nodes 37 & 38.

Dione will be rebooted due to kernel update once the job queue is drained. Dione is now in pre-reboot state and the job max time is set to 1h.

New software modules are available on Dione and Titan clusters. The modules are under validation period during which users (you) can try them out and confirm that there aren't any issues. The modules are still considered experimental and they may not work as expected or they may be removed if they cause issues to the cluster. After passing the validation period the modules will be considered stable and they will be available on the clusters permanently.

The modules are

ASE 3.22.1
GPAW 22.1.0
R 4.1.2
Bowtie2 2.4.5
STAR 2.7.10a
Tensorflow 2.7.0

The modules can be accessed on both clusters with command

module use /home/opt/modulefiles

after which you can see the modules with "module avail" and load them with "module load".

Please send us feedback if you face any problems or other issues with the new modules.
