Levi Morrison and I have co-authored a new prioritization mechanism for Slurm called LEVEL_BASED. To see why it is necessary, please see my other post about the problems with algorithms that existed at the time of its creation.
DEPRECATED: This has been deprecated by our new algorithm, Fair Tree. Yes, we really did replace this algorithm within a few months even though it worked great for us. See the post about Fair Tree for details.

Problems with Existing Slurm Prioritization Methods
UPDATE: Level-Based was replaced by Fair Tree, an even better algorithm that we created.
Levi Morrison and I have co-authored a new prioritization mechanism for Slurm called LEVEL_BASED. In order to understand why LEVEL_BASED is necessary, I have chosen to write this post about our issues with the existing options and a separate post about LEVEL_BASED. If you just want to see information about LEVEL_BASED, see the post LEVEL_BASED Slurm Prioritization Algorithm.
We want users from an account that has higher usage to have lower priority than users from an account with lower usage. There is no existing algorithm that consistently does this.
