the torus drawn as a chip with no crossings: each row a closed ring, the columns radial spokes. Under one waveform a cycle it is the slowest of the lattices that pass every rule: 1,254.2 ms at 1.08 ions per instruction, against the torus's 516.4 and the planar grid's 648.1. It runs under the one-waveform model (control.model simd_classes: one motion a cycle, the R22 split) on direct wiring, so its time is an upper bound for a direct machine. The study's 106 ms, which kept most of the torus's speed, was the programme before the R22 split.
