A hybrid MPI–OpenMP scheme for scalable parallel pseudospectral computations for fluid turbulence

► A two-level hybrid OpenMP/MPI parallelization scheme is presented for pseudospectral computations of fluid turbulence. ► The hybrid scheme leads naturally to a new picture for the domain decomposition of the grids. ► The hybrid scheme scales well up to ∼20,000 compute cores with a maximum parallel...
