Add parameter gpumodel=same for multi node-multi gpu parallel jobs.

To allow LSF more efficient scheduling for multi node multi gpu nodes (that require to run on same type of GPU's) parameter gmodel=same is very important. Today we can only define same model for CPU type but not for GPU type: Our clients are runni...

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...

THREAD limit to be set per HOST or PER CORE instead of PER JOB

The current THREADS limit on a queue level is set per job while it has to be set per HOST or per CORE. That is because current limit doesn't reflect the size of a job so is the THREADS limit is 600 it means that a single core job can produce up-to...

Enhance lsmake4 to support Grouped Target's in the latest version of make 4.4.1

Currently our tools are using Grouped Target's which don't properly work causing quite a bit of rework after the initial compile.

Allow resource limit ELIGIBLE_PEND_JOBS usage for APPS

I would like to have a limit ELIGIBLE_PEND_JOBS for the consumer APPS. The reason is an application which needs licenses from a license server. In case of many simultanously dispatched jobs the license server overloads. Up to now the resource limi...

tool to list out active and default base params - lsparams

Think of 'bparams' and the level of details that it provides with args '-la'. This helps in figuring out what all params are configured as default or what defaults values are affecting the scheduling. Such a tool does not exist for LSF Base config...

Ability to reserve GPUs in LSF advanced reservations

It's currently not possible to reserve GPUs in an advanced reservation with LSF, unlike CPUs (slots) and memory. For example, we have some hosts with 120 CPU slots and 8 GPUs. I want to create a reservation that reserves half of a node. I can do t...

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]" /...

Add possibility to assign cores from the same CCX in AMD CPUs to make use of the same L3 cache.

With a specific 2-core workload we noticed significant performance improvements of about 50% in shorter runtime when both cores reside on the same L3 cache group (CCX) of an AMD EPYC CPU.Therefore it would be very beneficial to be able to have LSF...

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...
