In the coming days, maintenance will be carried out on Slurm authentication, and job submission will not be possible during the change. An exact date and time have not yet been scheduled, since the compute nodes first need to be drained to clear running jobs and make the intervention as light as possible.

Update [30 abr 12.30 pm]

Slurm is updated to support the new native slurm authentication. The change was applied to some group machines, and it works except from wngpus. The rest of the machines needs to apply it in the next hour when puppet runs.

Update 30 abr. 15.00 pm

the intervention took longer than expected.

We still need to review some specific configuration details on a few nodes, but in general the cluster should be working properly.You can encounter issues when submitting jobs, contact us in this case.

Nodes under review: wngpu, wncmsgpu.
