MPI+OpenMP Parallelization for Elastic Wave Simulation with an Iterative Solver

In this paper, we propose and study the hybrid (MPI and OpenMP) parallelization for our novel approach to 3D numerical simulation of elastic waves with Krylov-type iteration method. The quality of the parallelization is justified by weak and strong scaling analysis.
