Hello, I would like to know if there is a way to limit CPU usage of a process and its child. I used setrlimit with RLIMIT_CPU, but all child process inherit from the same value as the parent. If I limit a process P0 to 2s, and P0 fork() 2 children (P1 and P2), P1 and P2 will have 2 new seconds of cpu time too. I would like a global CPU time for all my process from P0 and not 2s for each. A fork bomb can easily eat all CPU with this method. (I know that I can limit the number of process, but this is not the same usage). Is there a way to control this ? Or is it possible to limit CPU per user instead of per process ? Thanks.
