This paper describes a parallelization process of the Boundary Element Method (BEM) used in the wave diffraction force calculation. The wave environment is considered as a random process. Four computation stages are parallelized in this method. First, the global coefficient matrix is formed concurrently. The parallel Gaussian elimination solution scheme is then applied to solve the resulting system of equations. Third, the entire domain solution can be calculated simultaneously from the solved boundary information. Finally, the analysis of the diffraction forces due to random waves at different frequencies are carried out simultaneously. The speedup and high efficiency of the described process are illustrated by solving an example problem on a Kandall Square Research (KSR) parallel computing system. In addition, discussion of different parallelization strategies are presented.
