Of coarse, if I was here I would ask a couple of provocative questions, like:

How did you measured 145ns "local" memory latency and 275 "neighbor" memory latency? Not a pointer chasing, I guess.

Today certain vendors ( provide single system image computers without overhead imposed by cache coherency achieving computation density order of magnitude higher than the best from SGI. Couple of more famous vendors are pushing similar approaches.
Don't you think that for computationally-intensive workloads big cache-coherent systems are a dead end?
