We report results comparing the performance of pseudospectral methods on a single CPU and a single GPU. Our CPU implementations use FFTW and we compare serial and OpenMP implementations. Our implementations for Nvidia GPUs use CuFFT and we compare the performance of PGI FORTRAN CUDA, Nvidia CUDA and PGI OpenACC compilers for similar algorithms.
