Parallel 3D Viscoelastic Finite Difference Seismic Modelling

P 006 PARALLEL 3-D VISCOELASTIC FINITE-DIFFERENCE SEISMIC MODELLING TH. BOHLEN and B. MILKEREIT Institute of Geosciences Geophysics Kiel University Otto-Hahn-Platz 1 24118 Kiel Germany Summary Computational power has advanced to a state where we can begin to perform wavefield simulations for realistic (complex) 3D earth models at frequencies of interest to both seismologists and engineers. On serial plattforms however 3-D calculations are still computationally very expensive. To make use of the efficiency of modern network computers we implemented parallel 3-D elastic/viscoelastic FD codes which allow to distribute the work load among several PCs or workstations connected via standard ethernet in
