Let's try this from a different perspective... Is Linux able to assign

Well... The SMP kernel itself wil schedule a program to the CPU with the
lowest load. That's probably behaviour that you want.

Can you manually dictate where the program will "go" for execution, or is
this decision purely done behind the scenes? I suppose that really
doesn't matter so long as the default behavior tends to equalize the load
(s).

It's built into the scheduler. You have no control.

Not correct. You can get all the control you want.
man taskset <enter> should tell you all that you need, but for the
topicstarters benefit, since he probably don't have a *nix machine
running, here's a link to that man page online :
