Parts/Interconnect/IBM BlueGene/Q 5D torus
Why this part
Five dimensions rather than three, because average hop count falls as you add dimensions and BlueGene/Q had to reach 98,304 nodes without the diameter growing unacceptably. Ten links per node instead of six is the price, and at that scale cabling is a genuine engineering constraint rather than a detail. The routing logic sat on the Power BQC die alongside the cores, continuing the line's practice of buying no network at all.

“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.
