After a brief review of the means for characterizing lattice gases using cellular automata rules, we discuss the implementation of the rules for simulating hydrodynamic phenomena which can be described by the Navier-Stokes equations. Special emphasis is placed on data-mapping strategies and implementation through the use of the high speed and large memory resources offered by vector multiprocessors such as the IBM 3090 Vector Facility. We present performance data which pertain to square and hexagonal lattice gases, and discuss the limits of the approach used and its potential extendability to other areas.
