Abstract
Determination of the shortest distances between particles is one of the most time-consuming parts of molecular simulation. In this work, we demonstrate that the use of signed-integer storage of coordinates in a scaled box allows one to skip multiple conditional statements in realization of the periodic boundary conditions, which, in turn, increases the performance. Performance of the improved procedure was tested in the NVT Monte Carlo simulations for liquid krypton and water.Citation
