Abstract or Summary
  • We present the results of embedding a multigrid solver for Poisson's equation into the parallel 3D Monte Carlo device simulator, PMC-3D. First we compare the sequential multigrid implementation to the sequential Successive Overrelaxation (SOR) Monte Carlo code used previously in PMC-3D. Depending on the convergence threshold, we obtain significant speedups ranging from 6 to 15. The parallel multigrid implementation is done by extending the partitioning algorithm and the interprocessor communication routines used in the SOR implementation to service multiple grids. The Monte Carlo code with the parallel multigrid Poisson solver is 4 to 9 times faster than the Monte Carlo code with the parallel SOR code, based on timing results on a 32-processor nCUBE multiprocessor.
