Title Using mixed precision within DL_POLY's force and energy evaluations: short-range two-body interactions
Abstract Huge developments were made in molecular dynamics simulation methods in the last two decades, particularly in the ability to use large scale parallel platforms. In this report, we consider the use of mixed precision within DL POLY 4, a molecular dynamics simulation code developed by CCP5. In particular, we investigate using mixed precision within the calculations relating to the short-range force and energy contributions between an atom/ion and a near-by neighbour. We investigate the Ewald real-space kernel, the van der Waals potential calculations and the metal potential calculations.
