Sequoia supercomputer breaks simulation speed record, 41 times over

While we've seen supercomputers break records before, rarely have we seen the barrier smashed quite so thoroughly as by Lawrence Livermore National Laboratory's Sequoia supercomputer. Researchers at both LLNL and Rensselaer Polytechnic Institute have used planet-scale calculations on the Blue Gene/Q-based cluster to set an all-time simulation speed record of 504 billion events per second -- a staggering 41 times better than the 2009 record of 12.2 billion. The partnership also set a record for parallelism, too, by making the supercomputer's 1.97 million cores juggle 7.86 million tasks at once. If there's a catch to that blistering performance, it's not knowing if Sequoia reached its full potential. LLNL and RPI conducted their speed run during an integration phase, when Sequoia could be used for public experiments; now that it's running classified nuclear simulations, we can only guess at what's possible.

Watson heading to college, honing administrator-pranking algorithms

There comes a time in every young supercomputer's life when he or she must leave the house. Having taken the world of game shows by storm and made appearances at places like Sloan-Kettering, Citigroup and the Cleveland Clinic, Watson's ready to go to college. The advance three-year schooling will find a modified version of IBM's computer making its way to New York State's Rensselaer Polytechnic Institute, where it will be learning lessons in English and math. Amongst the course load are plans to sharpen Watson's cognitive skills and ability to manage data. The residency will also offer students a chance to get to work closely with one of the supercomputers that will one day rule us all.
