In the Whole Brain Emulation Roadmap there's a table of published guesses at computing requirements: most were in the range 10^14..10^18 FLOPS. (Plus a few outliers from people who think the brain does molecular-scale or quantum computing in microtubules.) The 500th biggest computer in the latest Top500 does around 3E13 FLOPS, while the top does 3E15 -- using GPUs, incidentally. Your link's on the high end of the range, though they're all kind of guessing. http://www.philosophy.ox.ac.uk/__data/assets/pdf_file/0019/3853/brain-emulation-roadmap-report.pdf http://www.philosophy.ox.ac.uk/__data/assets/pdf_file/0019/3... http://www.top500.org/list/2010/11/100 http://www.top500.org/list/2010/11/100
