I'm not sure that the NSA actually would want machines on that scale these days. Its probably a lot more economical to throw your money into lots of much smaller machines and occassionally link them up via networks. Unlike physics simulation problems, most crypto problems don't involve tight communication between the parallel processors, so the extra expense that the high speed buses represent would end up being a waste.
