Priority user and static priority fairshare

There are two ways to configure fairshare so that a more important user’s job always overrides the job of a less important user, regardless of resource use.

  • Priority User Fairshare: Dynamic priority is calculated as usual, but more important and less important users are assigned a drastically different number of shares, so that resource use has virtually no effect on the dynamic priority: the user with the overwhelming majority of shares always goes first. However, if two users have a similar or equal number of shares, their resource use still determines which of them goes first. This is useful for isolating a group of high-priority or low-priority users, while allowing other fairshare policies to operate as usual most of the time.

  • Static Priority Fairshare: Dynamic priority is no longer dynamic because resource use is ignored. The user with the most shares always goes first. This is useful to configure multiple users in a descending order of priority.
