Parallel Algorithm of Electromagnetic Wave Propagation in Complex Terrain Environment
摘要
Abstract
Simulation of electromagnetic wave propagation in complex terrain environment needs powerful computing ability. Parallel computing using cluster which is based on MPI can solve this problem commendably. This paper puts forward a parallel algorithm of electromagnetic wave propagation in complex terrain environment, and designs experiments considering task granularity and capability in parallel process. Simulation speed is improved in a cluster environment in laboratory. Methods of choose an appropriate task granularity for similar parallel problems is proposed.关键词
