Applications of Parallel Computing Algorithms to Three-Dimensional Modeling of Seismic Waves Generated by Complex Sources in Homogeneous Media.

Abstract

We describe a hardware upgrade that was performed on the nCUBE 2 massively parallel computer at MIT's Earth Resources Laboratory. The upgrade involved the installation of additional memory, additional disk space, and an additional small nCUBE 2 computer. The reason for performing the upgrade was to provide ERL with a computational environment suitable for conducting large-scale 2-D and 3-D wave propagation simulations. We also describe two recent projects that were performed on the upgraded nCUBE 2. One project was a 3-D simulation of earthquake-generated ground motion in the Boston Basin. The other project was the development of a parallel irregular-grid modeling code which is well-suited for 2-D modeling of regional wave propagation in the presence of surface topography.
