LOL. I'm working on one of those project at Sandia National Labs. We have a massive cluster of DEC Alpha boards, about 512 in the current machine with plans to add another 1024. Our machines are full size Miata cases, eight to a rack. I doubt that the JUMPtec boards have nearly 1 GF/per board, although we certainly could pack quite a few into 64 cabinets... Power consumption on our cluster (and on our previous Teraflops machine) is rather high. Our current limitation is current draw -- if we could reduce power consumption we could pack the machine more densely and have a faster machine. Cooling is also a big concern. Tramm -- o
