Message-ID: <CAMJ=MEfz7wkXpXYzpzc171nipkA8ruZGA1KvcX0C6QcKjVcT5A@mail.gmail.com> Date: Wed, 26 Feb 2014 20:24:52 +0100 From: Ronny Meeus <ronny.meeus@...il.com> To: linux-kernel@...r.kernel.org Subject: CPULoad measurement Hello My application consists of several hundreds of threads. I want to create a loadcontrol mechanism at application level so that when the cpuload of a group of threads crosses a certain (configurable) threshold, the threads will voluntary yield until the load condition is over. For this I need to have a mechanism int the kernel that calculates the consolidated load of each of the thread-groups. Is such a mechanism in place in the kernel? I could for example define a cgroup per group I want to define and assign the threads to the correct group. I have no clue whether internally in the kernel the total CPUload consumed per cgroup is kept. If that would be the case, it would be ideal. I do not want to make the sum of all the thread's load (for example based on the info in the proc filesystem) because this is generating too much overhead. Any hint/help/info is much appreciated.
