Abstract

A major research topic in geophysics deals with the modelization of the Earth interior, and seismic tomography is a means to improve knowledge in this field. In order to improve the accuracy of existing methods, huge quantities of information must be computed. We present in this paper the design of a software program implementing a fast seismic ray-tracing in an Earth mesh. We show that massively parallel computational resources may be used to process huge quantity of data. We present experimentations on several computational equipments with various hardware architectures (a parallel computer, a cluster, and a Grid) and report which parallel programming paradigm best suits each of these equipments.
