如何防止子分叉进程继承CPU亲和力？

Question

I have a server process that forks many child processes. The server process has affinity to a CPU core, but 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?

Answer 1

您可以在fork(2)和execve(2)之前使用CPU掩码中设置的所有位调用sched_setaffinity(2) execve(2) 。
