如果纱线cgroup正在运行许多线程，CPU限制公式仍然有效吗？

Question

从URL https://developer.ibm.com/hadoop/2017/06/30/deep-dive-yarn-cgroups/中我们看到了以下纱线cgroup的CPU限制公式，我的问题是，如果有很多线程（假设500个线程，每个线程都执行CPU密集型操作，例如无限循环操作），这些公式仍然有效）在每个容器中运行？就是说，如果线程数远大于每个容器的vcore数，yarn cgroup是否仍可以控制CPU使用率？

"In hard limit mode, YARN uses the following formula to calculate the CPU limit for each container.

C: number of physical CPU cores
P: strict limit percent
V: number of vcores on a single node manager
A: number of vcores for a single container

CPU_LIMIT = C * P * A / V;
In our example, a single container requests one vcore. The CPU limit for this container will be

CPU_LIMIT = C * P * A / V = 8 * 50% * 1 / 6 = 2/3 = 66.7%

And if there is another container requesting 2 vcores, the CPU limit for that container will be

CPU_LIMIT = C * P * A / V = 8 * 50% * 2 / 6 = 4/3 = 133%"
