ECMWF has scheduled a network system session to be held on Wednesday 13 March 2024 which will impact work on the Atos HPC. The session is expected to last for 4.5 hours from 12:00 UTC to 16:30 UTC.
During the session, there will be NO login access to hpc-login and NO user batch jobs submitted from hpc-login or via hpc-batch will run. Batch jobs submitted before the session which are not expected to complete before the sessions starts will queue until after the session has finished. Time-Critical Option 1 and 2 workloads will not be affected and will continue to run during the session.
Users with batch jobs to submit on Wednesday morning and which are expected to complete before 12:00 UTC should ensure an appropriate Wallclock time limit is set via the "#SBATCH --time" directive so that the job can be scheduled to run. Interactive jobs started with the ecinteractive command or running in JupyterHub before the system session may be terminated, but it will be possible to start new ones during the session.
The ECS class of service (ecs-login and ecs-batch) will remain available during the system session.
Check the ECMWF Service Status for up-to-date information on the service.
