  5. International Collaboration • Institution to Institution Agreement • Scripps Institute (US) • NERSC(US) • Hadley Center (UK) • CIRA (Italy) • RPN (Canada) • Individual participation in ES Project

  6. Network Diagram JAMSTEC-Network ES-Network Internet Fire Wall Authorized User Fire Wall Mass Data Transportation ES-LAN Data Earth Simulator

  7. Drastic cost reduction in Manufacturing • Development of an expensive system that requires many trial stages, such as fusion reactor • Development of an innovative machine that requires frequent model changes, such as autos and airplanes • Synthesis of new materials, such as proteins, medicines and nano-carbon-ubes etc.

  8. Paradigm Shift in Human’s Thinking Reductionism has made human’s thinking simple, and only neighboring, near-term conditions are taken into consideration in decision-making --- linear prediction Earth Simulator makes human consider global and long-term conditions and feedback them in decision-making ---nonlinear prediction
