Looks like you can build a smaller supercomputer using the quad chip PCI-e cards from PEZY: <a href="http:&#x2F;&#x2F;www.pezy.co.jp&#x2F;en&#x2F;products&#x2F;pezy-sc-quad.html" rel="nofollow">http:&#x2F;&#x2F;www.pezy.co.jp&#x2F;en&#x2F;products&#x2F;pezy-sc-quad.html</a><p>If the SC Quad power usage is anything like the -1 Quad&#x27;s 180w, you can fit ~83 of them on a single 15A breaker.<p>That&#x27;s 3 Tflops x 4 CPU x 83 cards = 996 Tflops. Count me in for a Petaflop on a single breaker.<p>I was excitedly watching <a href="https:&#x2F;&#x2F;www.parallella.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.parallella.org&#x2F;</a> but they haven&#x27;t released anything but their initial 16-core board thus far.
