Wavenumber Integration Synthetic Seismogram Calculations Using a Parallel Virtual Machine.
Abstract
The principal objectives of this work are to: (1) provide more accurate, and efficient means to compute, store, and retrieve synthetic seismograms for reference layered Earth structures and (2) examine limitations of using layered Earth structures to model principal features of regional seismograms in the presence of lateral heterogeneity. This annual report describes work completed in the first year of this two year project and very briefly describes work to be carried out in the second year. In the first year of this project a wavenumber integration program has been ported from a single processor application to a parallel processing environment using the Parallel Virtual Machine (PVM) software environment. This software allows the user to harness a network of UNIX workstations to perform calculations in parallel. A beta test version of the program is available upon request. Near linear speedup over a single processor has been realized with a heterogeneous network tested over both wide and local area networks.
