Abstract
Molecular dynamics codes are widely used on scalar architectures where they exhibit good performance and scalability. For vector architectures, special al-gorithms like Layered Link Cell and Grid Search have been developed. Nevertheless, the performance measured on the NEC SX-8 remains unsatisfactory. The reasons for these performance deficits are studied in this paper.
