Large Scale Atomistic Simulations on Nanostructure Evolution — •Jeffrey Kelling^1,2 and Karl-Heinz Heinig¹ — ¹Institute of Ion Beam Physics and Materials Research, Helmholtz-Zentrum Dresden-Rossendorf, Dresden, Germany — ²Institute of Physics, TU-Chemnitz, Chemnitz, Germany

The Kinetic Metropolis Lattice Monte-Carlo (KMC) method is a means of performing atomistic simulations of self-organization processes in solids at by far larger scales than those accessible via Molecular Dynamics (MD). GPUs currently provide the highest peak processing performance regarding both cost and energy consumption. We present a GPU implementation of KMC achieving up to two order of magnitude higher performance than a sequential reference implementation on a single core of a modern CPU. This enables atomistic simulations at experimental spatiotemporal scales.
