摘要
En 中文
The multiple reciprocity method is a recent generalisation of the well-known Boundary Element Method. It allows the numerical analysis of Poisson's problem in an efficient and elegant manner since it converts the classical domain integral coming from excitation to a summation of boundary ones. However, the method leads to the computation of higher order kernels so that the assembly of the linear systems is significantly increased. In this paper, it is shown that parallel computing allows a substantial reduction in CPU time. Different data distribution strategies have been implemented and compared using standard ScaLAPACK computational kernel. Tests have been successfully run on a 24-processor Intel Paragon.
