20 kW? Wow. I wonder what the future holds; 20kW is just an order of magnitude higher than you can draw from a normal 20 amp socket. I want a mips64 supercomputer in my basement.

It is highly likely there are 2 or even 4 32A 3-phase supplies into those cabs.

Looks like you can build a smaller supercomputer using the quad chip PCI-e cards from PEZY: http://www.pezy.co.jp/en/products/pezy-sc-quad.html

If the SC Quad power usage is anything like the -1 Quad's 180w, you can fit ~83 of them on a single 15A breaker.

That's 3 Tflops x 4 CPU x 83 cards = 996 Tflops. Count me in for a Petaflop on a single breaker.

I was excitedly watching https://www.parallella.org/ but they haven't released anything but their initial 16-core board thus far.

For what it's worth, I evaluated the SC5832 (and another small processor cluster) and just couldn't get performance out of it. A much smaller Xeon cluster of that period was significantly faster for less. Too bad because I liked the SiCortex people and the idea a lot.
