Earth Simulator Project in Japan

摘要: The Science and Technology Agency of Japan has proposed a project to promote studies for global change prediction by an integrated three-in-one research development approach: earth observation, basic research, computer simulation. As part the project, we are developing ultra-fast computer, “Earth Simulator”, with sustained speed more than 5 TFLOPS atmospheric circulation code. Simulator” is MIMD type distributed memory parallel system in which 640 processor nodes connected via fast single-stage crossbar network. Earth node consists 8 vector-type arithmetic processors tightly shared memory. peak performance total 40 TFLOPS. software system, operation supporting what called “center routine”. will be completed spring 2002.
