Rather than fretting about how to build the first machine capable of an Exaflop, Marc Hamilton is starting to think about what comes after that–the last Exascale computer.
No matter what you think about the future of ExaFLOP and ExaSCALE computing, the experts pretty much agree, improving the performance/watt will be one of the key challenges. Using today’s commercially available technology, an ExaFLOP system would require about 1,000 megawatts of power. That is about 50x more than the US Department of Energy’s 20 megawatt target for future ExaFLOP systems.
