Abstract
The treatment of the scattering processes which occur in the collision of electrons with polyatomic targets has been object of intensive theoretical studies in the last ten years or so, and several methods to solve the final scattering equations have been proposed1,2,3,4 by different groups each with specific features which treat at various levels of sophistication the physics of the electron-molecule scattering process. The intrinsic complexity of the models adopted to understand the behaviour of the scattering process requires the use of algorithms which exploit at best the programming features of the available top-class hardware and software technologies. While a full comprensive description of the different models has been given elsewhere,5 some general and common requirements that fit the needs of parallel computing have still to be exploited, in particular when huge cpu-demanding power is necessary such that required for the solution of the electron-molecule scattering equations. We outline below how we implemented our set of codes on parallel machines within the Single-Center-Expansion (SCE) framework description, showing specific numerical results on a typical, parallel MIMD architecture.
