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.
Best regards, Ronny
