[lxc-devel] cgroup cpuacct enhancement
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?

Marian, Thanks for the info. Paul Menage also directed me to containers@ lists.linux-foundation.org. I'm having a hard time finding out how to subscribe to that list. Do you know the procedure?

I personally think that this is possible. However I haven't done any research on that.

Ok, Greg.

You just need to send an email to containers-requ...@lists.linux-foundation.org with subscribe in the subject or body... The only issue I see so far is that the list seems to be down since Sep. 10... This is what one gets when accessing http://lists.linux-foundation.org/ : "This site is down for maintenance. We will be restoring service shortly. Thank you for your patience.
