Rice Researcher Breshears Wins Most Effective Engineering Methodology Award at SC98

Clay Breshears of Rice University is part of a team of computational scientists from the U.S. Army Corps of Engineers Waterways Experiment Station (WES) Major Shared Resource Center (MSRC) that was honored with the prestigious Most Effective Engineering Methodology award for its HPC Challenge project, "Dual-level Parallel Analysis of Harbor Wave Response Using MPI and OpenMP." The award was given at Supercomputing '98, held November 7-13, 1998, at the Orange County Convention Center in Orlando, Florida.

The code, CGWAVE, simulates the response of a harbor's surface to a collection of wave components coming in from the open ocean. Multiple wave components are needed for an accurate model, each of which can be run independently on separate processors. MPI is used to exploit parallelism associated with the sea-state model, while OpenMP is used to parallelize the conjugate gradient solver over the finite element mesh for each wave component. Using the University of Tennessee's MPI_Connect, the team performed the simulations simultaneously, using SGI/Cray Origin 2000 computers in two different locations—the MSRC at WES and the Aeronautical Systems Center MSRC in Dayton, Ohio.
