Abstract
In this paper, we report on the efficiency of parallelization for atomistic-level large-scale simulations. Tight-binding and ab-initio molecular dynamics simulations are carried out on a supercomputer HITAC S-3800/380 and on a parallel computer HITAC SR2201. We compare the efficiencies of the two different machines based on large scale simulations to investigate advantages and disadvantages of parallel architecture.
