Add Memory Statistics to Daily Statistics

When I wrote the daily statistics interface years ago, I had very little comprehension of the concept of Memory Efficiency, and therefore did not add memory_reserved, and mem_used, and max_memory to the daily statistics tables. But in todays HPC, ...

Provide ability to dump sequence of jobs ids considered by LSF scheduler for dispatch during a dispatch cycle

An old job which is pending in LSF may continue to remain pending with the reason "Individual host based reasons" while newer jobs continue to get scheduled. This may happen due to queue priority and fairshare settings. When running 'badmin diagno...

Increase max export rows for RTM

The default maximum number of rows RTM can export to Excel is 50k. It's possible to increase this (https://www.ibm.com/support/pages/modify-number-export-rows-you-can-set-rtm-console), but would be nice to have a larger option built into RTM.

Add Effective Memory Utilization to All Statistics Tables

RTM maintains a consistent set of ETL's across multiple dimensions. It is the same table structure for all of these ETL's. However, a key metric is missing from the ETL's and it's the effective memory utilization. In other words sum(max_memory) /s...

LSF Smart Memory Limit & Docker integration

Enabling the Smart Memory Limit conflicts with the Docker integration settings - in that, you cannot have both enabled at the same time. We believe the offending (Docker) config line is:LSB_RESOURCE_ENFORCE="cpu memory"

Now that Symphony Advanced Edition is properly reporting RSS and VSZ for tasks please update LSF Session Scheduler accounting log to include RSS and VSZ

Currently, the Session Scheduler accounting log always reports VSZ and RSS as Zero. It would be nice to report the actual numbers. I know from my Symphony training that the same was also true with EGO and resolved roughly 3 years ago. It would be ...
