Parallel and Vector Adaptations of the Underwater Finite Element Parabolic Equation Model

Abstract

This report describes optimization techniques for several vector and parallel versions of FEPE, a finite element underwater parabolic equation model code. Algorithms are presented for solving linked tridiagonal systems of equations, when the chief computational bottleneck is in FEPE on parallel, massively parallel, and vector machines. Sample execution times for a standard benchmark problem are also given. A broadband version of FEPE, which is highly efficient on vector computers and can be combined with parallel algorithms for even higher performance is presented.
