    Prev Next3.2. cpu
    The cpu subsystem schedules CPU access to cgroups. Access to CPU resources can be scheduled according to the following parameters, each one in a separate pseudofile within the cgroup virtual file system:
    cpu.shares
    contains an integer value that specifies a relative share of CPU time available to the tasks in a cgroup. For example, tasks in two cgroups that have cpu.shares set to 1 will receive equal CPU time, but tasks in a cgroup that has cpu.shares set to 2 receive twice the CPU time of tasks in a cgroup where cpu.shares is set to 1.
    cpu.rt_runtime_us
    specifies a period of time in microseconds (µs, represented here as "us") for the longest continuous period in which the tasks in a cgroup have access to CPU resources. Establishing this limit prevents tasks in one cgroup from monopolizing CPU time. If the tasks in a cgroup should be able to access CPU resources for 4 seconds out of every 5 seconds, set cpu.rt_runtime_us to 4000000 and cpu.rt_period_us to 5000000.
    cpu.rt_period_us
    specifies a period of time in microseconds (µs, represented here as "us") for how regularly a cgroup's access to CPU resource should be reallocated. If the tasks in a cgroup should be able to access CPU resources for 4 seconds out of every 5 seconds, set cpu.rt_runtime_us to 4000000 and cpu.rt_period_us to 5000000.
