On DOE's Exaflop plans


Some details are given here.
BAD HARDWARE WEEK Conclusion? Petaflop monsters only work at average 1% of projected peak computing  capacity !. 1 Exaflops will only deliver sustained 20 Pflops machine using current technology. With future technologies 50 up to 100 PFlops sustained. Each human brain has such a computational capacity ! Optical connections alone are able to spare 33% of Exaflops power budget. That is up to 6MWs ! A lot of wasted heat.
