Shouldn't the OS or even on a lower lever the CPU itself to manage this? Interesting idea. Similar to the way instruction scheduling in single cores is handled by the CPU. As the number of cores begin to increase to the 100's and eventually 1000's, there probably will be a hardware implemented core manager. Until that day, compilers will take a lot of the multi core management away from programmers (hence new things like .AsParrallel), but not all of it.

Introduced to programming by VB, grew up on C++, tangoed with a slew of other languages, and now mainly partying with C#.
