This paper is a summary of our experience feedback on GPU and GPGPU computing for two-dimensional computational fluid dynamics using fine grids and three-dimensional kinetic transport problems. The choice of the computational approach is clearly critical for both performance speedup and efficiency. In our numerical experiments, we used a Lattice Boltzmann approach (LBM) for the incompressible Navier-Stokes equations, a finite volume Flux Vector Splitting (FVS) method for the compressible Euler equations and a lagrangian particle approach for a linear kinetic problem.
