Priority user and static priority fair share

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

Priority user fair share

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 fair share policies to operate as usual most of the time.

Static priority fair share

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.
