Broadcast Speed Comparison
One source, same node placement style, different wiring and different broadcast construction. This is the old side-by-side broadcast idea, rebuilt with today’s structured crossed-cube tree.

Step 0 is the ready state. Click Next Clock Step to start wave 1. Copper edges and moving packets show the current wave; teal edges are already settled into the broadcast tree. The point of this page is the depth contrast: the hypercube uses the usual dimension tree, while the crossed cube uses your structured S/D broadcast construction.
