Scheduling of fork()ed process

Hi,


I have here a very specific workload that I want to test in Linux
without the "child-runs-first and in the parent's processor"
behaviour.

I know that this behaviour is very good for general workloads because
of the cache affinity; but in my specific case I want that a
short-lived fork()ed process starts to run immediately after the
fork(), in the other CPU.

I've modified sched.c:wake_up_new_task() in order to prevent the
scheduler to run the child first [it was easy, even for a newbie like
me :-)], but I'm not sure about how to make the child run in the other
processor.

Can anyone help me?


Thanks,
Daniel
