Parallelization of solution of boundary problems on quasistructured meshes using hybrid computations CPU + GPU
A. V. Medvedev, V. M. Sveshnikov, I. Yu. Turchanovsky

In the article describes parallelization technology of boundary value problems on quasistructured meshes with special decomposition method in a hybrid computing environment: the central processor (CPU) + graphics accelerators (GPU). Contains results of numerical experiments with a model problem, showing the effectiveness of the proposed approach.

Key Words
quasistructured meshes, algorithms parallelization, boundary problem, hybrid computations, CUDA, OpenMP
