R – Assign threads to run on a custom Core in Unix


Is it possible to run a particular thread/process on any core we want?
Since multi-core systems are available today . Is it possible to assign two (mutually independent ) segments of code run on any core we want to rather than wait for it to be assigned in a round robin fashion?
This way we can truly reap the benefits of parallel processing.

Is there a system call in the Unix flavours that lets us assign threads to specific cores?
