Computing in atmospheric science workshop 2003

The scale range the Earth Simulator can cover

only 104 at most which is far from the reality

The conventional upgrading due to the Moore’s law, namely, due to the technological progress of semi-conductor chips, is astoundingly far-a-way

A new algorithm is really invoked to make a revolutionary leap in Simulation Science


Computing in atmospheric science workshop 2003

Nature likes “stratification” !

☆ ‘Parameterization’ is one good example of the use of nature’s stratification

☆ But, nature dislikes discrimination

☆It is invoked to make an equal treatment of microscopic and macroscopic processes

★An equally connected algorithm of microscopic and macroscopic processes is indispensable
