Abstract:In this paper, we present a problem solving environment (PSE) for the large scale electronic structure calculations based on the O(N) tight binding method. We have developed a simulator named Fujitsu Tight binding Simulator (FuTiS). By implementing the O(N) method on parallel computers and introducing a common interface, we can perform the electronic structure simulations involving more than a few million atoms and expand the range of the application. We have performed the tight binding calculations to explore… Show more
