Performing kinetic lattice Monte-Carlo simulations of far-from-equilibrium processes on GPUs


Performing kinetic lattice Monte-Carlo simulations of far-from-equilibrium processes on GPUs

Kelling, J.; Heinig, K.-H.

Kinetic Metropolis lattice Monte-Carlo (KLMC) simulations can be applied to study systems without strong external driving forces, for example the evolution of nanostructures. An algorithm allowing nearest neighbor interaction in thermally activated processes has been implemented for GPUs. External driving forces can be modeled by adding appropriate rules to the cellular automaton. Ion-beam induced mixing, which is governed by comparatively long-ranged interactions, leads to far-from-equilibrium processes (defect relaxation) producing disordered structures. A plain implementation of long-range interactions reduces the performance on GPUs substantially. In this talk we present an efficient implementation of long-range ballistic displacements in GPU-KLMC.
