Rapid parallelization of the drift-diffusion model for semiconductor devices

The expensive reengineering of the sequential software and the difficult parallel programming are two of the many technical and economic obstacles to the wide use of HPC. We investigate the chance to improve, in a rapid way, the performance of a numerical serial code modelling semiconductor devices, exploiting the parallel features of shared memory achitectures. OpenMP seems to be the good choice in order to guarantee the portability, that is one of the big issues in parallel computing.
