Parallel Numerical Algorithms for Simulation of Rectangular Waveguides by Using GPU

摘要

In this article we consider parallel numerical algorithms to solve the 3D mathematical model, that describes a wave propagation in rectangular waveguide. The main goal is to formulate and analyze a minimal algorithmic template to solve this problem by using the CUDA platform. This template is based on explicit finite difference schemes obtained after approximation of systems of differential equations on the staggered grid. The parallelization of the discrete algorithm is based on the domain decomposition method. The theoretical complexity model is derived and the scalability of the parallel algorithm is investigated. Results of numerical simulations are presented.
