How the application efficiency is calculated in Spectrum LSF RTM

Question & Answer


Question

You want to know how Spectrum LSF RTM calculates the application efficiency.

Answer


Application efficiency calculated based on the data in grid_jobs table which collected by RTM gridjobs and gridpend binaries from LSF cluster.

RTM will aggregate the grid_jobs data every 5 minutes and the aggregation ETL calculates the application efficiency with the following formula:

1 For job stat in RUNNING or PROV, calculate the summary of the stime and utime, we mark it as SUM(stime + utime).

2 For job stat in RUNNING, calculate the summary of the run_time*max_allocated_processes, we mark it as SUM(run_time*max_allocated_processes).

3 Application efficiency = SUM(stime + utime) / SUM( run_time*max_allocated_processes)

Note the job will be ignored if its run_time is less than grid_efficiency_window.
