When MIGs (Multi-instance GPU) are enabled on a multi-GPU server, LSF should pack jobs with smaller number of MIGs on one physical GPU to keep a room for jobs with larger number of MIGs. Currently LSF is distributing the jobs on different physical...

License Scheduler - Minimum Preemption Time

It's been observed when the license scheduler preempts a job to free up license resources, the job can occasionally be resumed within 1-2 seconds if license features are freed up during that time. This leads to behavior where processes do not prop...

Consider AMD ccd in affinity string

Hello, Currently, using affinity string, we can target a core, a numa, a socket or memory, but not an AMD CCD (Core Complex Dies, L3 cache shared by 8 or 16 cores) Allowing jobs requesting less cores than available in a CCD (8 or 16 currently) to ...

Do not start jobs with less than X cores per host

It is useful for when ptiles or slots do not fulfill your needs. Using an example, we have an MPI code that requests 100 cores. We don't tell LSF how to grab those cores, and sometimes it will go out and span across 12 nodes, taking 19 cores on on...
