Spectrum LSF

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...

Improve bsub rejection messages for troubleshooting

Improve the error messages returned from bsub failiure. For example, provide the rusage string and potentially specified what is wrong with rusage. Here is current failure message: Error in rusage section. Job not submitted.

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...

Regular expressions in calculated fields

For some raw-data fields like res_req or effective_res_req in the job_acct index, it is right now not possible to extract single parameters like the mem-parameter in the rusage section. This could be achieved by supporting regular expressions (reg...

INCLUDE directive for lsf.cluster file

Its great to have INCLUDE functionality added in LSF and we're using heavily in our multiple LSF clusters. Its makes it easy to manage many clusters for common config edits and keep the farms compliant. I am logging this RFE to extend this feature...

For each job, records the number of execution host CPU cores in the job's table

As we evaluate the utility of SMT2/4/8, we would like to be able to measure the performance difference of the applications at scale by recording the number of slots of the compute host for every job. This would achieved by adding a tinyint unsigne...

Enhance lsmake4 to support Grouped Target's in the latest version of make 4.4.1

Currently our tools are using Grouped Target's which don't properly work causing quite a bit of rework after the initial compile.
