Due to an update required on the Lustre filesystem serving HPCPERM, SCRATCH as well as fws4, the ECMWF HPCF will be unavailable to run any standard jobs on:
Wednesday 2025-03-05 from 08:30 to 16:30 UTC
During the session, queued jobs will be kept on hold with the reason "Licenses", and will start once the session is over. At the same time, there will be a shorter, concurrent session on the AC cluster requiring a reboot of login, GPIL and GPU nodes. This session will cause those nodes, including hpc-login and hpc-batch, to be unavailable between 08:30 - 10:30 UTC. Note that, while you may connect after 10:30 UTC, the Lustre filesystems mentioned above will remain unavailable and any jobs submitted will be on hold until the end of the longer session.
ECMWF Operations, Time-Critical Option 2 and 3 suites, as well as some prepIFS work will continue to run normally since they use a separate set of filesystems and HPC complexes.
As usual, we encourage you to follow the progress of this and other system sessions on the ECMWF Service Status.
You may get in touch with us for any concerns of doubts by raising an issue through our ECMWF Support Portal.
