Re: Question about group scheduler cpu shares

Thanks Mike. So if I understand you right - tasks on interior nodes get their weight from task's nice level and not from some cpu.share setting. Two followups: 1.What is the function that translates from various nice levels to weight i.e. nice(0) == 1024 how to translate for other levels 2.How

Question about group scheduler cpu shares

Hi, The cgroup "cpu" subsystem's weight calculation using "cpu shares" is fairly clear when all tasks are attached to the leaf cgroups in "cpu" subsystem. For example in this cgroup hierarchy with tasks A.B,C and D and associated cpu shares: ROOT | + -Group1(3072) || | +- A(2048) || |
