Why not one really big core?

[silentbogo]

Contrary to popular beliefs, you can multitask on 1 core... be it old athlon/duron or p3/p4.

Multitasking and Simultaneous multithreading are not the same thing.

But I think more cores arent neccessarily the solution. Imagine 1 million cores, each corse running a simple trivial task, say 1+1 or 1+2. Now this needs some managing seeing what core is free, what is running what, and what is the result of that calculation, it will need a almost a separate managing processor.

Just look at modern GPUs as an example of such constructs: they all have a dedicated hardware for scheduling and resource allocation. Like NVidia Falcon processor (not sure what arch, but the new version is going to be a slightly modified RISC-V), or whatever AMD used in GCN 4.
