Abstract

Large-scale three-dimensional (3D) multi-phase-field (MPF) simulations of polycrystalline grain growth behavior in a system containing finely dispersed mobile second-phase particles have been performed using our multiple-GPU computation technique and evaluated the scalability of computational performance of the multiple-GPU computation on the TSUBAME2.5 GPU-supercomputer at the Tokyo Institute of Technology. In order to obtain high performance in the large-scale simulation, we employed the domain decomposition method and the overlapping method modified from one developed in our previous work to hide the time for the data-communication by that for the computation. The results demonstrated the multiple-GPU computation technique achieved very good performance scalability in the large-scale 3D MPF simulations taking into account the coarsening of the particles by the Ostwald ripening.
