[slurm-users] Getting usage reporting from sacct/sreport

Hi Thomas et al,

I have just written a Linux shell script which does exactly what you are asking for.

Please use “—allocations” option in sacct command to generate aggregated resources usage per user.

You may also use awk Linux command to summarize all CPU usages. 

More advanced awk command may also summarize all GPU usages.

I have also placed the script on the GitHub but it is private now until we clear it for public.

Traceable resources normalization along with traceable resources weights are needed for more fair usage reports. in this case “billing” value represents combined (max or sum of individual traceable resources) billing unit. Note by default this values equals to the number of CPUs used.
