MPI Implementation of an Acoustic Modeling method for Beowulf Clusters
Abstract
This thesis presents a parallel implementation of an acoustic finite difference modeling method due to Alford, Kelly and Boore that numerically synthesizes cross time sections of complex geological subsurface structures. The work required included porting an existing sequential version from the Sparc architecture to the Intel platform, followed by developing a parallel implementation of this program on a Beowulf cluster using the Message Passing Interface (MPI). MPI is a standard for message-passing libraries. MPICH, a portable implementation of the Message Passing Interface, distributed freely by Argonne National Labs, was used. The Beowulf cluster at the Allied Geophysical Laboratory, University of Houston, is a low cost substitute for a super-computer and is used for running parallel and computation intensive applications. The parallel implementation of the finite difference acoustic modeling method provides considerable performance improvements over the sequential version. The results are included to substantiate this claim.
