Do you think a beige box can simulate 10 mm^3 worth of human cortex?
It too 4 kNode worth of a Blue Gene/L to render half a cartoon mouse
at 1/10 realtime. And the simulation did exercise the interconnect.
Which wasn't exactly Ethernet, you know.

Do you think Google wires their nodes in a 3d torus topology?
