I don't know if there is any possibility to define the CPU, on which a special thread should run on. Is there any?
Because usually, this is something your OS should handle because it knows best about all the other parallel processes. And it's perhaps not always the best solution for your application to split all your threads on perhaps the 4 CPUs of a quadcore, if there is another application which also needs lot of CPU power (I would thought, that in this case, it should be a lot faster, if your application uses 2 CPUs and the other application the other ones). But as I said, usually this is something your OS should take care about.
