Dcpusets.rst48 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.

Dhugetlbfs_reserv.rst416 * 当cpuset被配置时，它打破了严格的hugetlb页面预留，因为计数是在一个全局变量上完
417 * 成的。在有cpuset的情况下，这样的预留完全是垃圾，因为预留没有根据当前cpuset的
418 * 页面可用性来检查。在任务所在的cpuset中缺乏空闲的htlb页面时，应用程序仍然有可能
419 * 被内核OOM'ed。试图用cpuset来执行严格的计数几乎是不可能的（或者说太难看了），因
420 * 为cpuset太不稳定了，任务或内存节点可以在cpuset之间动态移动。与cpuset共享
422 * 页的可用性，作为一种最好的尝试，希望能将cpuset改变语义的影响降到最低。
