Abstract

Today it is quite common to find in academic and research environments as installation of heterogeneous computers connected via ethernet. In this paper we present a very cost-efficient solution for the parallel implementation of seismic algorithms in a network of heterogeneous workstations using PVM (Parallel Virtual Machine). Two algorithms were analyzed and implemented using different implementation approaches: (1) A minimum time ray-tracer based on the Fermat's principle operating on irregular grids and (2) An algorithm that calculates numerical solutions to the eikonical equations and computes the travel times for the first arrivals of seismic waves on a 2D grid by finite difference extrapolation.
