This paper describes an efficient parallel algorithm of the cellular automaton (CA) method for microscopic fluid dynamics simulations. The CA method is parallelized with so‐called multispin coding and with one‐dimensional domain decomposition. The parallel CA method has a constant computational load balance and small data transfer between only nearby domains. We have applied the parallel CA method to a large‐scale Poiseuille flow simulation and an immiscible two‐phase flow simulation on a Fujitsu AP1000 with 64 processors.
