It's a bit of a chicken-and-egg problem. In general, devs don't target machines that don't exist.

But from some quick searching, excel will split out independent calculations into their own threads. So for that, the answer seems to be: it depends. If you're using 20 cores to calculate a single thing, it seems like the answer is "no". But if you're using 20 cores to calculate 20 different things, it seems like the answer is "yes".
