Parallel numerical algorithm for the traveling wave model

Abstract

A parallel algorithm for the simulation of the dynamics of high-power semiconductor lasers is presented. The model equations describing the multisection broad-area semiconductors lasers are solved by the finite difference scheme, which is constructed on staggered grids. This nonlinear scheme is linearized applying the predictor-corrector method. The algorithm is implemented by using the ParSol tool of parallel linear algebra objects. For parallelization, we adopt the domain partitioning method; the domain is split along the longitudinal axis. Results of computational experiments are presented. The obtained speed-up and efficiency of the parallel algorithm agree well with the theoretical scalability analysis.
