N2 - We present a parallelization strategy for our novel iterative method to simulate elastic waves in 3D land inhomogeneous isotropic media via MPI and OpenMP. The unique features of the solver are the preconditioner developed to assure fast convergence of the Krylov-type iteration method at low time frequencies and the way to calculate how the forward modeling operator acts on a vector. We successfully benchmark the accuracy of our solver against the exact solution and compare it to another iterative solver. The quality of the parallelization is justified by weak and strong scaling analysis. Our modification allows simulation in big models including a modified 2.5D Marmousi model comprising 90 million cells.
