Parallelization of the seismic ray trace algorithm

Abstract

This article presents the parallelization of seismic ray trace algorithm. The chosen Urdaneta's algorithm is shortly described. It provides wavelength dependent smoothing and frequency dependant scattering thanks to the implementation of Lomax's method for approximating broad-band wave propagation. It also includes Vinje et al. wavefront propagation technique that provides fairly constant density of rays. Then the parallelized algorithm is preliminarily tested on synthetic data and the results are presented and discussed. © 2012 Springer-Verlag.
