GPU Parallelization of a Hybrid Pseudospectral Geophysical Turbulence Framework Using CUDA

GPU Parallelization of a Hybrid Pseudospectral Geophysical Turbulence Framework Using CUDA

An existing hybrid MPI-OpenMP scheme is augmented with a CUDA-based fine grain parallelization approach for multidimensional distributed Fourier transforms, in a well-characterized pseudospectral fluid turbulence code. Basics of the hybrid scheme are reviewed, and heuristics provided to show a poten...
