I found the problem. For anyone having a hard time with this too.
First of all manpages are your friend. Read the error description.

I had overlooked the second note on EPERM.
It says that all CPUs have to be available to the scheduler ( e.g. sched_setaffinity ). Otherwise it fails with EPERM.

Hope this helps.
