Titan takes over as world's top supercomputer

Tools

As biotech research becomes more of a computational endeavor, it's worth paying attention to the arms race of sorts for the world's fastest supercomputers. Last month Oak Ridge National Laboratory took over the No. 1 spot in the world with its Cray XK7 supercomputer called Titan, which the government-funded lab will use to crunch data in a variety of fields, including biology. The Titan, which makes quadrillions of calculations per second, edged ahead of Lawrence Livermore National Laboratory's Sequoia supercomputer, which moved from No. 1 to No. 2 in the ranking of the world's 500 fastest computers.
