Cache Coherence?

Well we all know some of the multi-CPUs have snooping implementation on their cache lines and memory blocks.

So the question is, does the Multi-GPU, or even the streaming processor has this feature?

I don’t think it’s as important as what this forum is supposed to talk about here, coz programming is all about algorithm, but if anybody got some idea, please put it up, and it will be appreciated.
