Porting on Parallel Platforms of a Tool for Simulating the Effects of Lightning Strokes on Telecommunication Buildings: A Comparison on Preliminary Results About Performances and Accuracy on SIMD and MIMD Architectures

摘要

In the framework of the UE CAPRI project, the Artemis subproject deals with porting on parallel architectures of a Method of Moment (MoM) code for electromagnetic design and hardening of telecommunication centres against the effects of lightning strokes. As a preliminary stage of the work, QR and LU algorithms for large complex matrix inversion were implemented both on Alenia's Q_UADRICS (SIMD) and Cray T3D (MIMD) platforms. The detailed results obtained from several test runs performed on each platform were reported elsewhere [HSSD95]. In this paper a comparison between the performance, scalability and accuracy results obtained from the abouv-mentioned tests will be reported and discussed.
