Description
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.
