Job packing on GPUs when MIG is enabled

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...

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 ...

job select statement improvement

I have hosts with exclusive resources and some with a dynamic resource. A few hosts have two exclusive resources. The job submit: $ bsub -R 'select[ defined(res1) || (defined(res2) && dynamic_pool==loaner_host)]' I would expect this job to...

Group jobs to same cluster when using bsub -cluster feature

Goal: Group together lsf jobs, "regression", in such a way that bsub -cluster feature directs all jobs in the group to the same cluster. Proposal: a) bsub submits all jobs in a job array to a single cluster bsub -cluster all -J "ArrayName[1-10]" /...

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...

Multiple queues request for job - consider taking in account queue limitations and lsf.resources for better job dispatching.

Today, when we submit a job with multiple queues (bsub "high risk") The job will be dispatched to a relevant queue by examine parameters such as queue status(open/closed), queue hosts, time-limit. In a situation, where a queue "high" have a ujob_l...

Array job maximum running jobs should be honored across multiclustered environments

Our users submit array jobs, but due to many factors may want to limit the number of running tasks at a time, not only from the source cluster, but total running jobs of that array for all clusters involved ( we have many clusters that use multicl...

Reporting both host-based pending reason and main pending reason

"LSF does not support reporting both host-based pending reason and main pending reason (about license)." Let me provide a portion of the bsub statement from our case to exemplify the customer's dilemma. bsub -R "rusage[mem=3000.00:duration=1m,md_r...

Run LSF file IO operations within the container.

LSF jobs using containers depend on mounts within the container. These mounts are not available on bare metal where LSF runs file operations. The bare metal dependency means that LSF file related operations, -o, -f, -E, -Ep, etc. will not have acc...

Correct on Design Flaw in Session Scheduler

Currently the Session Manager and Service Director operate in the same CGROUP on the first execution host which causes a race condition that if a task on the first execution host pushes the memory use above the memory limit (aka mem-eater process)...
