World's largest supercomputer will be used for nuclear stockpile research
IBM to build a 20 petaflops supercomputer, called Sequoia, for the Lawrence Livermore lab; a petaflop stands for a quadrillion floating-point operations per second; to put Sequoia’s computing power in perspective, what it can do in one hour would take all 6.7 billion people on Earth with hand calculators 320 years, if they worked together on the calculation for 24 hours per day, 365 days a year
