An implementation of the reactive empirical bond order (REBO) potential has been developed for parallel molec ular dynamics simulations. This reactive, many-body po tential has been widely used for molecular dynamics sim ulations of solid- and gas-phase carbon and hydrocarbon species, but until now has not been available for distributed computing environments. Several novel or interesting fea tures of the implementation are described, including a pair list structure suitable for bond-order potentials and user customizable integration algorithms. The algorithm is scal able and ef´Čücient down to approximately 400 atoms per processor, and has been ported successfully to four differ ent distributed computing architectures.
