Map memory reservation to cgroup memory.low

Mapping the memory reservation of a job to the cgroup memory.low could protect jobs from running short on memory, while in parallel allowing more memory to be used if it's available. The soft limit instead of a hard limit should prevent users to b...

Affinity scheduling must take L3 cache hierarchy into account

Newer CPUs have multiple L3 caches, with dedicated cores per L3 cache. Running multi-threaded jobs on all cores within a shared L3 cache can reduce runtime in our cases up 70%, compared to running over multiple L3 caches. Think of the AMD EPYC 935...

LSF job query filter on pending jobs without providing pending reasons

For large LSF clusters, the bjobs command takes significant time to gather the pending reasons (-p, -pei, -pe, -pi) making the query much longer than requesting all jobs. Suggest a new bjobs option to filter on pending jobs without supplying the p...

Add Column PSUSP to Job Group Output and Allow Filtering by Name Similar to Job Name filtering in "bjobs"

For our user community, Jobs that go into PSUSP are important for the flow owners to investigate and our flow owners are using Job Groups. The inability to easily see the number of Jobs that are in PSUSP is limiting the effectiveness in the use of...

Please provide a bresources option where we can find the default reservation unit per defined resource: job, task, host

Currently, it's not strait forward for a user to be able to see what the default reservation units are for things like memory, swap, license resources, etc. It would be nice if there were a bresources option to show the default allocation unit's f...

Please Log the Pre and Post Exec Runtimes in MBD and through Events

The Pre-exec start event is logged, but there is no event for the post exec. So, it's almost impossible for us to track the runtimes of post exec without adding additional layers to our external reporting. We would prefer these metrics to be track...
