由子进程继承的Cpu亲和力 [英] Cpu affinity inherited by child process

问题描述

我有一个服务器进程，分叉许多子进程，服务器进程与cpu核心的亲和力，我不希望该亲和性被子进程继承（而不是os应该在哪里运行这些进程）。有没有办法脱离父进程与cpu亲和关系？

I have a server process that forks many child processes, server process has affinity to cpu core, i don't want that affinity to be inherited by child process (rather os should handle where to run these processes). Is there a way to delink parent child processes with respect to cpu affinity?

感谢

推荐答案

您可以致电 sched_setaffinity（2） 所有位在 fork（2） 之前， execve（2） 。

You can call sched_setaffinity(2) with all bits set in CPU mask after the fork(2) and before the execve(2).
