Multigrid Method using OpenMP/MPI Hybrid Parallel Programming Model on Fujitsu FX10

PublishTime：2022-05-31

●Motivation of This Study
■Parallel Multigrid Solvers for FVM-type appl. on Fujitsu PRIMEHPC FX10 at University of Tokyo (Oakleaf-FX)
■Flat MPI vs. Hybrid (OpenMP+MPI)
■Expectations for Hybrid Parallel Programming Model
◆Number of MPI processes (and sub-domains) to be reduced
◆O(108-109)-way MPI might not scale in Exascale Systems
◆Easily extended to Heterogeneous Architectures:CPU+GPU, CPU+Manycores (e.g. Intel MIC/Xeon Phi); MPI+X: OpenMP, OpenACC, CUDA, OpenCL
