You can use taskset on linux. You can also lower the priority of a process, but unless the CPU(S) are busy, a process will get as much CPU as it can use.
I have a library for dedicating thread to a core, called Java Thread Affinity, but it may have a different purpose to what you have in mind. Can you clarify why you want to do this?
