Enhance the Support Tool to be able to remove ZOMBI jobs and create a log of exec hosts and pgids that need to be cleaned
We had an issue where LSF could not keep up with dispatch due to high numbers of ZOMBI jobs. We would like the ability to shut down LSF and clean up the ZOMBI jobs via a Database repair to accelerate the time-to-restore of the LSF clusters.
Make Queue Open/Close/Act/Inact 'all' Requests a single event
We recently had a serious issue that required us to close/inact all of our queues, and then perform a database repair using the IBM support tool. However, when we started LSF, all but one of the queues was Open/Act again. This was due to the suppo...
Make the TCP Backlog for the MBATCH and MBATCHD Query Port Configurable for Large Clusters
We have been monitoring the TCP backlogs for LIM, MBD, and the Query port for some time, and there are periods where the MBD query port becomes overloaded resulting in a higher than expected count of UNKNOWN and sometimes eventually ZOMBI jobs, an...
To see how much memory is reserved on a host, we need to parse the bhosts -l <hostname> command, and it doesn't give us info about which job is reserving how much memory. I'd either like to see one of the following: bhosts -o 'jobid reserved...
Enable License (LS) Visibility on Spectrum Application Center
We would like users to have visibility of the availability of solver license on LSF Application Center. We are using version 10.2.0.9 and were told by support that this feature is no longer supported. This is necessary as it enables users to have ...
bsub should accept a cpu_efficiency parameter to allow cpu over-commiting in the pool
It's rare for a job to achieve close to 100% cpu efficiency. Often, jobs have a peak cpu requirement during its execution lifetime but use less cpus in average. If bsub could be told that a job is expected to run with a given cpu efficiency, LSF c...
Change job submit time to include milliseconds for precision.
Job submit time to include milliseconds for precision. Instead of HH:MM:SS, make it like 12:29:05.1234. This will enable this column to be used as a unique identifier when generating data in an incremental fashion. We are extracting the RTM data a...
Add lsb.params setting to limit the number of times a job can be redispatched upon either a pre-exec failure of job initilization failure
We currently have jobs that will bounce from host to host either based upon a pre-exec failure, or a job initialization failure. This can impact > 500 hosts and cause an increase in MBD memory use. It would be nice to have a setting such as: MA...
Add a JobID's column to the table grid_hosts_gpu and show in Job Details page
It would be very beneficial to reporting to see which jobid's are allocated to which jobs when it comes to the GPU assigned. This way, the user can look at the ELIM graphs and know that their job is actually using the GPU in question. Right now, y...
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...
