Accelerating electrostatic pair methods on graphical processing units to study molecules in supercritical carbon dioxide (2014)
Journal Article
Baker, J., & Hirst, J. (2014). Accelerating electrostatic pair methods on graphical processing units to study molecules in supercritical carbon dioxide. Faraday Discussions, 169, https://doi.org/10.1039/C4FD00012A

Traditionally, electrostatic interactions are modelled using Ewald techniques, which provide a good approximation, but are poorly suited to GPU architectures. We use the GPU versions of the LAMMPS MD package to implement and assess the Wolf summation...
