dual-core dual project

Having no life and bored a lot, I like to come up with threads that might help someone out, but usually don't affect me. Here's another one:

Now that multi-core processors are becoming more ubiquitous, I think it's time we had a thread that helped people learn how to attach a project instance to a specific processor. For instance, you might be addicted to BOINC, but you might want to give one of the cores the opportunity to search for a Mersenne prime.

How would one do that?

Assuming you have a single dual-core CPU (so 2 CPUs):

Configure your BOINC client to use a max of 1 processor, and run one instance of the Prime95/mprime client, thus each one will use a CPU for itself. You could also set the affinity of the Prime95 client to one of the CPUs so it doesn't bounce around between processors which should force the OS to keep BOINC on the other one.
