But I think that architecture will be seen inside PCs in ten years or less :-) It's being years that Intel is able to create a CPUs with 30-80 cores, but it's kind of impossible to keep efficient a single coherently shared memory with that many cores. You need to do as GPUs do. But I think such flat architecture is not so good with a large amount of legacy code and it's not as efficient as possible with tons of partially serial code. So I think you will see the more complex hybrid I have explained. And I think D is not ready yet for such hybrid architecture yet.
