IBM can now hold the claim of building the current fastest supercomputer in the world. The Top500.org website reports that the company's Sequoia supercomputer "achieved an impressive 16.32 petaflop/s on the Linpack benchmark using 1,572,864 cores."
For comparison, that's about 1.55 times as fast as the last supercomputer to hit the number one spot, the “K Computer” in Japan that was made by Fujitsu. The K Computer is now in the number two position on the world's official supercomputer speed list. This also marks the first time that a US-based supercomputer has taken the top spot on the list since November 2009.
The IBM Sequoia is currently installed in the US Department of Energy's Lawrence Livermore National Laboratory in California. In addition to being superfast, the BBC reports that the Sequoia is actually better for the environment. It uses 7.9 megawatts of power compared to the K Computer's 12.6 megawatts.
