Abstract
“Earth Simulator” is a high speed parallel computer system for computational earth science, which is a part of earth science field for understanding the Earth and its surroundings such as atmosphere, ocean and solid earth through computer simulation. Computational earth science is useful for weather forecast, prediction of global change such as global warming and E1 Nifio event, and some earthquake related phenomena such as mechanisms of earthquake or disaster prediction. The Science and Technology Agency of Japan promotes global change prediction research through process study, earth observation, and computer simulation. Development of the “Earth Simulator” is a core project to achieve this objective. “Earth Simulator” is being developed by Earth Simulator Research and Development Center (ESRDC), which is a joint team of National Space Development Agency of Japan (NASDA), Japan Atomic Energy Research Institute (JAERI) and Japan Marine Science and Technology Center (JAMSTEC). The goal of the “Earth Simulator” is to achieve at least 5 Tflop/s sustained performances in atmospheric general circulation model (AGCM) program with the resolution of 5-10 km grid on the equator.
