Abstract
We present the results in embedding a multigrid solver for Poisson's equation into the parallel 3D Monte Carlo device simulator, PMC-3D. First wehave implemented the sequential multigrid solver, and embedded it into the Monte Carlo code which previously was using the sequential successiveoverrelaxation #SOR# solver. Depending on the convergence threshold, we have obtained signi#cant speedups ranging from 5 to 15 on a single HP 712#80 workstation. Wehave also implemented the parallel multigrid solver by extending the partitioning algorithm and the interprocessor communication routines of the SOR solver in order to service multiple grids. The Monte Carlo code with the parallel multigrid Poisson solver is 3 to 9 times faster than the Monte Carlo code with the parallel SOR code, based on timing results on a 32-node nCUBE multiprocessor. 1 Introduction Semiconductor device simulation is an important aspect of the computer aided design #CAD# of integrated circuits. As semiconducto...
