Next to priority access, wait time is the largest factor: the longer a job waits to execute, the higher its priority to be scheduled. This seems appropriate, but it competes against the fair-share factor, which prioritizes jobs for underserved users. | Next to priority access, wait time is the largest factor: the longer a job waits to execute, the higher its priority to be scheduled.

Since the ''PriorityWeightJobSize'' will not be used, the more complex "small-relative-to-time" algorithm will be disabled. | Since the ''PriorityWeightJobSize'' will not be used, the more complex "small-relative-to-time" algorithm will be disabled. |

| The modifications to ''slurm.conf'' must be pushed to all systems. The ''scontrol reconfigure'' command should be all that is required to activate the altered priority caclulation scheme. |
