Rob, <With 256 CPUs what is the worst case hop? When
you plot all combinations of hops worst case is a very
low percent. Average latency is very good.>

Sure, if all you have is one active CPU and an idle interconnect fabric. Toss in 255 other CPUs doing remote accesses simultaneously and you'll run into real scalability issues.

If you can show me one 256-CPU system that can be done in a UMA/RUMA/SKUMA way, I'd sure like to see it.

<Nice too is aggregate memory bandwidth, 12.8 GByte/s direct
attached, 25.6 GByte/s routed.>

You sure about that? I've read each EV7 processor has 6.4 GB/sec memory bandwidth. And adding the "routed" bandwidth is mere marketing fluff. If you want to hype up the EV7, you might want to stick to facts, like the fact that the bandwidth is per-processor, unlike any Intel-based server.

<Heard at IDF McKinley has 3X the memory bandwidth of Itanium. 6.4 GByte/s... shop and compare!>

Compared to the popular P3 Xeon which has only 800 MB/sec bandwidth, McKinley has eight times the bandwidth. Or compared to Foster, McKinley has twice the bandwidth. If the Xeon is growing faster than the Alpha platform, imagine how fast the McKinley platform will grow.
