LSFProxyd is a new solution to help scheduler handle queries effectively. This RFE is to enable persistent blocksing rules for heavy query hitters. Same has been discussed with John Welch in a separate discussion.
From the documentations, it seems LSF proxyd is currently showing its logs from perfmon view style of command and this RFE is to enable lsf proxyd logging same as other daemons are logging currently. e.g. mbatchd.log, mbschd.log.. similarly we sho...
Expand API (or bjobs -o option) to report memory reservation on a per-job basis
Determining per-job memory usage is valuable, but we also need to be able to see, on a per-job basis, how much memory job(s) have reserved at a point in time. Partly we need to be able to compare to the actual memory use to see if they're over-res...
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...
LSF struggles in large farms with many running pending jobs and thousands of users in fairshare tree. LSF's struggle with heavy query activity is well documented. It would be great if LSF can provide telemetry on its own performance and what speci...
From the documentations it seems, LSF Proxyd does not differentiates between a service account vs an individual user account and can't have diff policies for diff user accounts. Our farms have a good mix of service accounts which launch thousands ...
Cleanup user details with bqueues -lr output if they don't have running/done jobs in system
Currently, we can find thousands of entries for all users even though they have ZERO STARTED jobs as listed in bqueues -lr output. For some of larger farms, these entries are close to 7M records and bqueues -lr takes long time to return the data. ...
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...
allow to limit cpu usage to the number of slots requested
currently, when a user submit a job, there's no way in LSF to limit the cpu consumption.
recently, we discover that it's possible to limit cpu usage OS side using cgroup, by putting a value in the 'cpu.cfs_quota_us' file of the '/sys/fs/...
