MPI+OpenMP Hybrid Parallel Algorithm Performance Research on Two-Dimensional Compressible Flow Field Simulation

Abstract:

In the multi-core CPU cluster parallel environment, use MPI+OpenMP hybrid parallel algorithm to optimize the numerical simulation program of two-dimension compressible flow field. Test the program which has been optimized, and compared to the program which has been optimized only by the MPI algorithm, get the conclusion that the MPI+OpenMP hybrid algorithm will have advantages in some conditions, and do some specific research on the application of hybrid algorithm used in the flow field simulation, illustrate in what conditions the MPI+OpenMP hybrid will have advantages.
