地球シミュレータ
The K computer used over 60,000 commercial scalar SPARC64 VIIIfx processors housed in over 600 cabinets. The fact that K computer was over 60 times faster than the Earth Simulator, and that the Earth Simulator ranked as the 68th system in the world 7 years after holding the top spot, demonstrates both the rapid increase in top performance in Japan and the widespread growth of supercomputing technology worldwide.
