A portable parallel implementation of a fractional step method to solve 3D unsteady incompressible Navier-Stokes equations on MIMD machines is described. The context currently considered involves uniform grid spacing in one of the directions. A parallel decomposition strategy and its implementation on a portable parallel programming system (Charm) is described. Some optimizations including one that reduces the cost of parallel convergence tests are described. Performance results for calculation of flow in a driven cavity on different parallel computers are presented.
