We describe an algorithm for computing nonbonded interactions with cutoffs on a graphics processing unit (GPU). We have incorporated it into OpenMM, a library for performing molecular simulations on high performance computer architectures. We benchmark it on a variety of systems including boxes of water molecules, proteins in explicit solvent, a lipid bilayer, and proteins with implicit solvent. The results demonstrate that its performance scales linearly with the number of atoms over a wide range of system sizes, while being significantly faster than other published algorithms.
