Monte Carlo electron trajectory simulations have been adapted to run on a parallel supercomputer. The increased speed achieved by parallelization of the Monte Carlo code results in the ability to model small probability events easily. The techniques

A parallel implementation of a Monte Carlo algorithm for modeling the scattering of electrons in solids and the resulting X-ray production is described. Two important issues for accurate and fast parallel simulation are discussed-random number genera

Molecular-dynamics methods are used to model diffusion in a \ensuremath{\Sigma}=5 [100] Al tilt boundary and in bulk. The diffusion coefficient D and activation energy Q for atoms in the boundary and in bulk are calculated for several different Al em
