In this paper, the two dimension incompressible Navier-Stokes equations with pseudo-spectral method are solved using the related subroutines in FFTW and CUFFT. Compared with the codes on CPU, the performance of the codes on GPU is much better, especially when the resolution increases. For the resolution of 2048 × 2048, the acceleration reaches 14.45 times. We also try to combine MPI (Message Passing...
