Simulation of nanoscale catalytic physico-chemical processes by the kinetic Monte-Carlo (KMC) method requires a sufficiently large computational power. Creation of «exact» parallel simulation algorithms for GPUs is quite problematic. In this paper, we study the possibility of applying cellular automata block-synchronous modes to KMC method simulation. New block-synchronous modes are proposed which are implemented on a GPU with high efficiency and with a higher fidelity of original model dynamics reproduction.
