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...

In the world of Multi-core processors, the context switches per second has become a KPI. It should be a standard performance metric like mem, r1m, etc.

When we try to oversubscribe hosts, it would be very beneficial to have ctx/second available as a base metric. It's available in all OS' these days. We could set a busy threshold for that say above 40k/second. For the longest time (maybe 31 years)...

Allow RTM to show jobs 'submitted' between ranges from job details page

We are in the middle of a bench-marking activity and it occurred to me that there is now way to say in RTM show me jobs that were submitted between these two dates. It would be helpful to have that filter available.

Allow Session Scheduler to support the queue level Job Starter when the Session Spreads to Multiple Hosts

In testing of Session Scheduler, it works perfectly, on secondary hosts, it does not seem to respect our job starter which will limit our ability to deploy Session Scheduler more broadly. Closing this gap is important.

Allows Session Scheduler Account Directory and moving parts to support the lsf.conf variable LSB_STDOUT_DIRECT.

We recently were able to confirm that if the user leaves off the SSCHED_ACCT_DIR in lsb.params, that they can set the same as an environment variable, and eventually the Session Scheduler account file will end up in that location, but the users re...
