Abstract

Benefits from parallelization of sequential TRQR application were analyzed and presented in this paper. The TRQR program based on the Particle-In-Cell method is used in simulations of particles trajectories in the electromagnetic field. To estimate the performance of parallelized program some formal and informal measures were provided. Analysis was based on three main issues. First-if and how parallel computing influenced program efficiency. Secondly, the way that system reliability increases and thirdly, how this solution improves the extent to which the available hardware computing power is used. The paper also presents the methodology that was used for code re-engineering in order to get a parallel version on the basis of its sequential version.
