badmin appclose/appopen for maintenance of a specific application

For maintenance reasons it would be helpful to close/open applications for dispatching like for queues and hosts by the command badmin qclose/qopen and badmin hclose/hopen respectively.

Provide a method to allow LSF simulations to be captured by a customers RTM

Provided a customer set's up a RTM hostname, and credentials, when a simulation is started, register the simulation clusters data collector and the cluster itself with that RTM and then enable collection for the duration of the simulation. Name th...

LSF Smart Memory Limit & Docker integration

Enabling the Smart Memory Limit conflicts with the Docker integration settings - in that, you cannot have both enabled at the same time. We believe the offending (Docker) config line is:LSB_RESOURCE_ENFORCE="cpu memory"

Affinity support for windows compute servers

We have a mixed Linux/Windows cluster. Unfortunately the affinity string in the resource requirement is not supported on Windows. This leads to several problems: 1. jobs with affinity settings will not be dispatched to windows nodes 2. less perfor...

Provide Access to Job Buckets for Analysis

Currently RTM contains quite a bit of information on current cluster state, but it provides limited information about the state of the scheduler, what job buckets exists, and the dispatch rate from these various buckets. Create an interface that p...

LSF: tmp (in tmpfs) monitoring when cgroup enabled

when cgroup is enabled on both OS & LSF, it's now possible to account tmp usage for jobs when /tmp FS is in tmpfs. ("cache" value of "memory.stat" cgroup file, that can be excluded from swap using "LSB_CGROUP_MEM_INCLUDE_CACHE" parameter) Is i...

Multiple esubs (master + remote) in a multicluster setup

We use LSF in a multicluster configuration. We also use an esub to dynamically assign which jobs are sent to each cluster. As far as I'm aware, only one esub (on the master) can be used. We would like to have functionality for esubs on the remote ...

Add Memory Statistics to Daily Statistics

When I wrote the daily statistics interface years ago, I had very little comprehension of the concept of Memory Efficiency, and therefore did not add memory_reserved, and mem_used, and max_memory to the daily statistics tables. But in todays HPC, ...

Create a way to prevent a job with an SLA from using another SLA's hosts/slots/memory if the other SLA is under-committed

LSF hosts come and go, and when you create an allocation that uses exact numbers, there are times when a Pool can be over and under committed. In the case of an under-committed pool today, consumers from other pools can leverage free slots from th...

Increase max export rows for RTM

The default maximum number of rows RTM can export to Excel is 50k. It's possible to increase this (https://www.ibm.com/support/pages/modify-number-export-rows-you-can-set-rtm-console), but would be nice to have a larger option built into RTM.
