This paper presents the implementation of a parallel solver for the 3D Poisson equation applied to gradual HBT simulation in a memory distributed multiprocessor. The Poisson equation was discretized using a finite element method (FEM) on an unstructured tetrahedral mesh. Domain decomposition methods were used to solve the linear systems. We have simulated a gradual HBT, and we present electrical results and some measures of the eciency of the parallel execution for several solvers. This code was implemented using a message-passing standard library MPI and was tested on a CRAY T3E.
