The Altix NUMA interconnect has the same speed as far as I can recall as
Hypertransport. It is the distance (real physical cable length) that
creates latencies for huge systems. Sadly the Hypertransport is designed
to stay on the motherboard. Hypertransport can only be said to be fast
because its only used for tinzy winzy systems of a few processors. Are
you saying that the design limitations of Hypertransport are an
advantage?
