The Hybrid-Cluster Multilevel Approach to Solving the Elastic Wave Propagation Problem

We propose in this paper an integrated approach to creating algorithms and software to simulate seismic problems. Our extended co-design concept considers supercomputer architecture at all stages, beginning with the physical and mathematical formulation of the problem, and then developing an algorithm and code. In particular, we compare the efficiency of the parallel implementation (on a supercomputer equipped with GPU) of algorithms for solving two mathematical statements of dynamic elasticity problem for the numerical modeling of seismic wave fields in 3D media, which is typical of volcanic structures.
