Abstract. The multifrontal LU method is implemented
to solve drift-di usion models with large sparse matrices arising
in the simulation and optimization of semiconductor devices.
The performance of this method is compared with the LU algorithm
without multifrontal scheme on different computers in
the case of a realistic double heterojunction transistor.
