Abstract

The calculation of the electron-electron (e-e) scattering rate is the key point in the ensemble Monte Carlo simulation of quantum well THz lasers. Its exact calculation would take most of the whole CPU times. In this paper, we develop a parallel algorithm to speed up the simulation process: the execution of ensemble Monte Carlo algorithm is in the root node, and the calculation of e-e scattering rate is distributed into other 25 nodes. The corresponding parallel algorithm is realized in our computer cluster system using message passing interface (MPI) library. Our practice shows that this parallelization of the serial EMC is simple and easy to realize the implementation.
