Parts/Interconnect/NEC Earth Simulator crossbar
Why this part
640 nodes joined by one single-stage crossbar, meaning any node reached any other in a single hop at 12.3 GB/s, a figure nothing else came close to in 2002. It also occupied a purpose built building and consumed a substantial share of the machine's budget and floor area. The Earth Simulator's dominance was as much this network as the vector processors, and both were beaten on cost rather than on capability.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
