I'll take 80 cores just for the processes (Score 1)

I've got 106 processes running on my XP laptop and I'm not even doing work right now. (At which point add another good dozen++ processes.)

And lots of these processes are already multi-threaded. (Including most of the tools and frameworks I use and some of the code I'm writing.)

So even though some of this sounds theoretical, I don't think I even need any kind of software upgrade to benefit from having an 80 core processor today just for scheduling processes. (Though, the memory bandwidth issues others have pointed out would need some attention.)

Cheers,
Richard
