Keys to Exascale are Improving Power and Programming Efficiency

Over at the Nvidia Blog, George Middleton writes that Chief Scientist Bill Dally’s ISC keynote discussed how power efficiency and application efficiency are some of the toughest Exascale challenges. Reaching exascale, according to Dally, will require a 25x improvement in energy efficiency – 50 gigaflops (or billion floating point operations per second) per watt vs. the 2 gigaflops per watt from today’s most efficient systems. And, contrary to what some believe, manufacturing process...
