Abstract

PVM is an inexpensive, but extremely effective tool which allows a researcher to use workstations as nodes in a parallel processing environment to perform large-scale computations. The numerical approximation and visualization of seismic waves propagating in the Earth strains today´s largest supercomputers. Timings and visualization are presented for large Earth models run on a ring of IBM RS/6000s which illustrate PVM´s capability of handling large-scale problems.
