How are priority and fairshare set up in the cluster

Webb3 sep. 2024 · Hi all, The SLURM cluster I am administrating needed to activate accounting, so each users activities would be measured and fairshare in SLURM could applied. Now this introduced a problem with our cryosparc master setup, because all jobs from cryosparc master needs to run as a particular cryosparc single user. The Slurm fair-share formula has been designed to provide fair scheduling to users based on the allocation and usage of every account. The actual formula used is a refinement of the formula presented above: The difference is that the usage term is effective usage, which is defined as: UE 1. is the effective usage of … Visa mer As of the 19.05 release, the Fair Tree algorithm is now the default, and theclassic fair share algorithm is only available … Visa mer The fair-share hierarchy represents the portion of the computing resourcesthat have been allocated to different projects.
