Title Using mixed precision within DL_POLY's force and energy evaluations: long-range interactions and fast Fourier transforms
Abstract DL POLY 4 is a molecular dynamics simulation code developed by CCP5. In this report, we consider the use of a simple mixed-precision methodology within the Smoothed Particle Mesh Ewald (SPME) method for systems with long-ranged ionic interactions. We show that such a method can be successfully used within DL POLY and that, for some of the test problems, the overall execution time was reduced by 14%.
