Can only root move programs to different processors via this program? Or can any user move their own or other programs to different processors? In the first instance, it is useless and unusable. In the second instance, please give me an account on an important box so that I can demonstrate the security impact to you... The scheduler must try to do the best. Yes, we know -- the scheduler does a poor job at the moment... Never let root try to do a job the operating system should do itself. Furthermore, never let a user try to do it, either. Unless you prefer a system you never let people onto. And if that is your use case, you are better off choosing something which has infinite flexibility, and then disconnecting it from the net.
