Parallelization of a 3D magnetostatic code using High Performance Fortran

Numerical simulation in electrical engineering allows one to reduce development costs by predicting device performance. An accurate prediction often requires 3D models, inducing high storage capacity and CPU power needs. As computation times can be very important, parallel computers are well suited to these models. 3D simulation in electrical engineering is based on recent research work (Whitney´s elements, auto-gauged formulations, discretization of the source terms) and it results in complex and irregular codes using sparse matrices, where data accesses are done via indirect addressing. We present the results of the parallelization of a 3D magnetostatic code using High Performance Fortran (HPF). This high level programming language allows a simple and efficient approach to parallel machines. It provides both easier maintenance of the code and higher software productivity for electrical engineers
