ULHPC User Guide 2020

To cope with the arrival of the new aion cluster, we have completely reworked the seminal Slurm configuration in place since 2017 to bring a new setup able to federate both cluster in a simpler, robust and consistent manner.

This new configuration drastically changed the QOS configuration in favor of a more simpler and consistent setup based on priority. The updated fairsharing algorithm, configuration and limits should allow for a fairer and transparent allocation policy, compliant with EuroHPC and PRACE recommendations and the new cost model and ULHPC resource allocations policy for research projects and external partners (approved by the rectorate on July 7, 2020).

The below ULHPC User Guide provides instructions and technical details of the new configuration, with impacts for your daily workflow.
