As part of the announcement today of the Top500 list of supercomputers:
“When Sequoia is really firing on all cylinders, also sometime later this year, it will hit 20 petaflops per second. The way Livermore explains it, if every single person on earth worked nonstop on a calculator for an entire year, they could do the same number of calculations in 320 years that Sequoia cranks out in an hour.”
