[slurm-dev] The number of maximum allocated cpu cores in a time interval

[Sefa Arslan]

I am getting the number of allocated cpu cores at an instant of time  
via sacct (keeping the start and end interval very short, it seem very 
reasonable)

for example:

sacct --start=2013-11-01T17:00  -X --end=2013-11-01T17:01 
--format="jobid,ncpus,start,end


and sum the ncpus values using awk.



How can I get the maximum number of allocated cpu cores in a time 
interval. For example I want to know how many cpu cores used at most  
last month.  Giving --start and --end interval long,  and summing the 
ncpus may cause  multiple count of the same cpu core (if a few jobs had 
started and ended on the same CPU core in the given time interval)

thanks alot.
