This paper considers an approach to fluid simulation known as Lattice-Boltzmann method. This method uses cellular automata which roughly resembles fluid microdynamics.

Two implementations of this method presented. One uses CPU for all calculations and the other puts most of the calculations on graphics card. Performance measurements of these implementations accomplished.

Simulation of developing of Karman vortex street behind a cylindrical obstacle is performed in order to verify convenience of the mode
