The last decade has seen the development of Lattice-Gas (LG) schemes as a complementary if not alternative method for the simulation of moderate Reynolds-Number Navier-Stokes-Flow. After a short introduction we present a detailed discussion of implementation features for a specific 2D-LG algorithm, which runs in parallel on a workstation-cluster, discuss simulation results and maximum CPU performances. Finally, we attempt to point out present problems and perspectives of these algorithms on virtual parallel machines.
