multiprocessing is already implemented for you in the standard
library.
Of course it does not require heavy hardware requirements.

You can take advantage of multi cores, just not with threads but with
processes,
which BTW is the right way to go in most situations. So (assuming you
are not
a troll) you are just mistaken in thinking that the only way to
use multicores is via multithreading.
