Task Level Parallelization for Seismic Modeling and Inversion

Abstract : This paper present experience with using PVM to parallelize \Dseismic inversion code developed in the Rice Inversion Project. We use coarse grain parallelism to dynamically distribute simulations over several workstations. When doing modeling, this strategy works efficiently, allowing us to reach an speedup of almost 4.5 on a cluster of 6 IBM RS6000 workstations. When doing inversion, however, we are currently limited to speedups of 2.4 on 3 workstations.
