Abstract

Abstract A parallel algorithm for numerical solution of a generalized unsteady 3-dimensional advection-diffusion equation for a mesoscale meteorological model is considered. Efficiency of parallel implementations of the solver with Message Passing Interface (MPI), Open Multi-Processing (OpenMP), and NVidia Compute Unified Device Architecture (CUDA) technologies was compared. It was shown that on the mesh of 25625632 nodes the speedup of the program reaches 18 for OpenMP and MPI implementations and 38 for CUDA.
