Effective r15s/r1m/r15m values for job reservations

When using run queue length indices in rusage strings, there should be an option to have the value divided by ncpus. Since in the "total load used for scheduling" the r15s/r1m/r15m are taken from lsload -E and divided by the specific ncpus for tha...

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...

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...

Enable option for hardcoding GPU memory request like its available for CPU memory request

At this moment IBM offers features of hardcoding CPU memory. We have implemented this feature in our cluster with esub scripting. Similarly we want to have same feature available for GPU memmory (gmem) to be hardcoded. I have raised ticket to our ...

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)...

Set a limit for service class

It would be useful to set a limit in lsb.resources for Serive Class "SLA" in order give some minimum guarantee with SLA and set a maximium number of resorucese usable in this SLA.It would be excellent to indicate the limit with the number of nodes...

Enhance GSLA to enable in-queue preemption

The Guaranteed SLA system allows sharing of Resources defined by ServiceClasses. We would like to use that to allow two or more groups to pool and share compute slots, wherein they typically unused slots would be available to all of the groups. Th...

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...

Allow preemption of shared gpu jobs (j_exclusive=no) by higher priority job queues.

We need the LSF support for preemption of shared gpu jobs. Currently GPU preemption is supported only for jobs in mode j_exclusive=yes This is a very big problem as we have a significant waste of gpu memory resource. because if a lower priority jo...

Add support to Kerberos ticket with new "renew-until" date for already submitted jobs

While using Kerberos ticket forwarding on a LSF cluster: Currently TGT found on the submission host is copied to LSF cache and forwarded to the execution host at job submission; These tickets can be renewed automatically by LSF until the TGT "rene...
