Resizable jobs submitting into fairshare queues or host partitions are subject to fairshare scheduling policies. The dynamic priority of the user who submitted the job is the most important criterion. LSF treats pending resize allocation requests as a regular job and enforces the fairshare user priority policy to schedule them.
Their share assignment
The slots their jobs are currently consuming
The resources their jobs consumed in the past
The adjustment made by the fairshare plugin (libfairshareadjust.*)
Resizable job allocation changes affect the user priority calculation if the RUN_JOB_FACTOR or FAIRSHARE_ADJUSTMENT_FACTOR is greater than zero. Resize add requests increase number of slots in use and decrease user priority. Resize release requests decrease number of slots in use, and increase user priority. The faster a resizable job grows, the lower the user priority is, the less likely a pending allocation request can get more slots.
The effect of resizable job allocation changes when the Fairshare_adjustment_factor is greater than 0 depends on the user-defined fairshare adjustment plugin (libfairshareadjust.*).
After job allocation changes, bqueues and bhpart displays updated user priority.
