Because "Preemption scheduling" is actually for the jobs in different queues.

LSF today has no such feature or concept of in-queue preemption.

the new feature maybe work like this:

define a INQUEUE_PREEMPT=[[userA,80%] [userB,20%]] ...

For example, the queue has total 1000 slots, so userA can use 800, userB can use 200.


If there is no userB jobs, userA can use all of 1000 slots.

If userB submit 100 jobs, userA should suspend 100 jobs, let userB run.

If userB submit 300 jobs, userA should suspend 200 at max(20%), let userB run 200 jobs totally.
