Parallel iterative solvers for unstructured grids using a directive/MPI hybrid programming model for the GeoFEM platform on SMP Cluster architectures

摘要

In this paper, a n efficient parallel iterative method for unstructured grids developed by the authors for shared memory symmetric multiprocessor (SMP) cluster architectures on the GeoFEM platform is presented. The method is based on a three-level hybrid parallel programming model, including message passing for inter-SMP node communication, loop directives for intra-SMP node parallelization and vectorization for each processing element (PE).
