Can you say more about this? I'm afraid I don't understand what you are trying to do here. What I'm worried about is systems where the memory latency time for local versus remote nodes might be 2-3 to 1. That is, it takes 2-3 times as much time to access memory on a remote node. (On older machines, the memory access time ratio's could have been as bad as 12:1 or 15:1.) So accessing non-local memory can be a really, really big deal. And this isn't just theoretical, but have you considered what might happen on a 8 core AMD machine?
