Explosive growth of computer performance has been bringing us the better grasp of global society.
Now with top computers, a new era of social applications has begun: microscopic simulations of our world and society. Such top computers with 10PFLOPS or more performance, simulations of billions to trillions of complex elements possible, and the number and their complexity will grow with next Exascale and future Zetascale computers.
With such computational power, we can challenge complex behavior of substance with direct simulation using molecular models, and social phenomena using models of each human, each vehicle and each transaction distributed and networked in global space.
This team challenges such microscopic simulations for macroscopic phenomena, which we call the "Neo-Avogadro Challenge", with K and future computers of Exascale and beyond.
