On DD November 2022 at 12 UTC AA, the default Atos cluster will became unavailable for essential Slurm and security updates. In preparation for it, the complex will be drained and jobs scheduled to finish after DD June 2022 at 10 UTC will be automatically redirected to other complexes. During short transition phase it is possible that your batch jobs and interactive session to hpc-login are hosted on a different complexes. Consequently, some general Slurm commands (see HPC2020: Batch system) executed on hpc-login node will not be able to communicate with batch jobs running on another cluster. You can find more information on how to manage jobs between complexes in the HPC2020: Multi-complex SLURM management page.
