Rechner-Cluster

We are experiencing issues with Slurm's batch controller which causes all Slurm commands (sbatch, squeue etc.) to time out. Our team is investigating the issue and working on a quick solution. Until then, job submission will not be possible. Running jobs might run as usual but exit with failures if connections to the controller fails. Results might still be valid.

We have singled out the problem and are still working on a solution. For the time being, job submissions are disabled to keep the controller in a stable state for all running jobs.

The batch system is fully operational again. Please review all of your jobs that ran during the time frame above and resubmit them in case of failures. We apologize for the inconvenience.

Due to repeated issues with the GPUs on the GPU dialog node login23-g-1, the node will be under shorthand maintenance on 2025-12-10 and cannot be used until further notice.
A technician will perform an on-site hardware diagnosis and component modifications which require the node to be shut down.

Please consider using an interactive GPU job or the Jupyterhub with the interactive node n23i0001 for short GPU computations.

The maintenance tasks are finished for today.

Monday morning we will have to restart our Slurm database and this will cause Slurm commands to be unavailable for the planned downtime.
Jobs will not be able to be submitted.

Works ended. Any jobs that failed to submit should be resubmitted.
