The Top500 ranking of supercomputers today recognized the Lawrence Livermore National Laboratory’s Sequoia as the fastest computer in the world. The computer, an IBM Blue Gene/Q, was designed to be extremely energy efficient. Like previous Blue Gene machines, it’s powered by low frequency and low power embedded PowerPC cores–in this case, an astonishing 1.6 million of them. Sequoia produces 16 petaflops of computation muscle. That’s 16 quadrillion operations per second. It’s an important stepping stone on the way to exascale computing–machines that will be 50 times as fast as today’s fastest.
