2.10. Task Control Groups

There have been various proposals in the Linux arena for resource management/accounting and other task grouping subsystems in the kernel (Resgroups, User Beancounters, NSProxy cgroups, and others). Task Control Groups is the framework that is getting merged in 2.6.24 to fulfill the functionality that lead to the creation of such proposals. TCG can track and group processes into arbitrary "cgroups" and assign arbitrary state to those groups, in order to control its behaviour. The intention is that other subsystems hook into the generic cgroup support to provide new attributes for cgroups, such as accounting/limiting the resources which processes in a cgroup can access.

For example, cpusets (see Documentation/cpusets.txt) allows you to associate a set of CPUs and a set of memory nodes with the tasks in each cgroup. The CFS group scheduling feature uses cgroups to control the CPU time that every cgroup can get. Other various resource management and virtualization/cgroup efforts can become task cgroup clients. The configuration interface is described in Documentation/cgroups.txt
