For two years, the most powerful computer on Earth sat in Yokohama, Japan, and its sole purpose was to simulate the Earth itself. When the first-generation Earth Simulator came online on March 11, 2002, it clocked 35.86 teraflops on the LINPACK benchmark -- nearly five times faster than ASCI White, the previous record holder. The American supercomputing community called it the "Computenik moment," a shock reminiscent of Sputnik. Japan had built a machine capable of modeling the planet's entire atmosphere and ocean systems down to a resolution of 10 kilometers, and it had done it with a clear, singular goal: to understand what climate change was going to do to the world.

The Earth Simulator Project began as a Japanese government initiative in 1997, commissioned jointly by the Japan Aerospace Exploration Agency (JAXA), the Japan Atomic Energy Research Institute, and JAMSTEC -- the Japan Agency for Marine-Earth Science and Technology. NEC won the c...

The Earth Simulator topped the TOP500 list of the world's fastest supercomputers from 2002 until September 29, 2004, when IBM's Blue Gene/L prototype finally surpassed it. During those two years, the machine ran holistic climate simulations that modeled both atmospheric and ocean...

The original Earth Simulator gave way to the Earth Simulator 2 in March 2009, an NEC SX-9/E system that traded raw node count for per-node performance. ES2 had a quarter as many nodes but each delivered 12.8 times the computing power, achieving a peak of 131 teraflops and a deliv...
