Abstract

The Earth Simulator is an ultra high-speed supercomputer. The research and development of the Earth Simulator started in 1997 as one of the approaches in the Earth Simulator project which aims at the promotion of research and development for understanding and prediction for global environment change. Conceptual design and basic design of the Earth Simulator have been finished so far. According to the design, the Earth Simulator is a distributed memory parallel system which consists of 640 processor nodes connected by an internode crossbar switch. Each processor node is a shared memory system composed of eight vector processors. The total peak performance and main memory capacity are 40Tflop/s and 10TB, respectively. In this paper, the concepts of the Earth Simulator system and the outline of the basic design are presented.
