Abstract
A standard asymptotic close-coupling method based on a perturbation te chnique is adapted for use on massively parallel computers. The calcul ation of K-matrices and cross-sections is partitioned over the process ors according to incident electron energy. Use of external disk during the calculation is eliminated. Linear scaling with the number of proc essors is achieved for a 128-node Intel iPSC/860 and a small farm of S un Spare 10 workstations.
