描述 / Description

Motivation

当前版本 PC1 大约需要使用一个半的 CPU core， 假如同时启动 20 个 PC1 任务，大概会空出来 20 个使用了一半的 CPU cores，这些被使用了一半的 cores 通过 damocles-worekr 已经有的设置 cpuset 功能规划后会有两种使用情况，要么直接空闲，要么随机的被系统分配给 PC2 C2 任务。前者会产生浪费，而后者看似没有浪费，但可能会引发一个问题，PC2 和 C2 任务有可能会抢占整个（或大多数） cpu 的使用权，可能会导致 PC1 任务效率降低。

所以希望能够有设置 CPU 使用权重功能合理规划 PC2 和 C2 任务使用那些 PC1 剩余半个的 cores。
