Is it possible for LSF to automatically set UJOB_LIMIT dynamically/adaptively based on actual load on queues?

    Hi, folks,

    A common situation is, when the queue load is low, we want to relax or remove the slot/job limit per user; while if the queue load is high, we want to tighten the limit per user. Is it possible for LSF to handle this automatically? I've gone through the LSF documentation and saw no such configurations.

    Thanks,
    Nathan

    One way is to write an external monitoring program to check the load of a queue, then use LSF live configuration feature, e.g. issue bconf command to modify the limits without restarting LSF.
