On scalability issues of the elastodynamics equations on multicore platforms

Abstract : Understanding the wave propagation with respect to the structure of the Earth lies at the heart of many analysis both in the oil and gas industry and for quantitative seismic hazard assessment. One of the most widely used techniques to solve the elastodynamics equation is the finite difference method because of its simplicity and numerical efficiency. In the last two decades, the parallel efficiency of this numerical method has been demonstrated through many applications on various parallel platforms. The complexity induced by multicore platforms both in terms of fine-grained parallelism and considering the memory hierarchy justifies revisiting these conclusions. In this paper, we underline the impact of such platforms on standard implementations.
