After winning top honors as the fastest supercomputer in the world -- for now, anyway -- IBM's Sequoia is getting ready to go to work for the Lawrence Livermore National Laboratory. Its duty: help manage the United States supply of nuclear weapons. "Much of the modeling for defense, aerospace, medical research and anticipating natural disasters is done on supercomputers," said analyst Rob Enderle.


IBM's Sequoia supercomputer headed the latest Top500 list of the world's fastest Supercomputers. The twice-yearly roster was released at the 2012 International Supercomputing Conference in Hamburg, Germany, in June.


Sequoia will be restricted to weapons management and will be moved off onto its own classified network. National Nuclear Security Administration spokesperson Courtney Greenwald was not immediately available to provide further details.


"Much of the modeling for defense, aerospace, medical research and anticipating natural disasters is done on supercomputers," Enderle said. "Without them, we would be effectively out of a number of markets and largely be incapable of truly anticipating and properly planning for those moments when Mother Nature has a hissy fit."




"In Sequoia, we have 1.57 million compute cores running concurrently," Rosenfield stated. "We need a highly efficient operating system that scales with the size of the system."


IBM supercomputers make up nearly 43 percent of the latest Top500 list, followed by HP with more than 27 percent.
