[lxc-devel] cgroup cpuacct enhancement

[Martin.Perry at Bull.com]

Hello.

I apologize if this is not the right list for this question, but it was 
the best match I could find. I'm working on a project to estimate the 
power consumption of jobs running on a Linux HPC cluster.  We've been 
looking into the possibility of producing this estimate using cgroups with 
the cpuacct subsystem.  cpuacct currently collects only cpu time.  If it 
also collected cpu cycles we could use these two values to calculate the 
cpu frequency and estimate the job's power consumption.  So my questions 
are:
Is it feasible to enhance cgroup cpuacct to provide this additional data 
(number of cpu cycles)?
Is there anyone actively working on cgroups who would be willing to make 
this change?

Regards,
Martin Perry
