| D | cpusets.rst | 48 the resources within a task's current cpuset. They form a nested
59 policy, are both filtered through that task's cpuset, filtering out any
60 CPUs or Memory Nodes not in that cpuset. The scheduler will not
67 cpusets and which CPUs and Memory Nodes are assigned to each cpuset,
68 specify and query to which cpuset a task is assigned, and list the
69 task pids assigned to a cpuset.
103 The kernel cpuset patch provides the minimum essential kernel
124 - Each task in the system is attached to a cpuset, via a pointer
127 allowed in that task's cpuset.
129 those Memory Nodes allowed in that task's cpuset.
