  • Abstract
    Domain decomposition method (DDM) and a hybrid MPI/OpenMP programming model both provide powerful strategy for performance computing. For large-scale partial differential equations, this paper presents a hybrid MPI/OpenMP model based on overlapping DDM and carries out numerical experiments. Numerical experiment results demonstrate that the proposed method has a better parallel performance.
