abstract = {Analytic bond-order potentials (BOPs) provide a way to
compute atomistic properties with controllable accuracy. For
large-scale computations of heterogeneous compounds at the
atomistic level, both the computational efficiency and
memory demand of BOP implementations have to be optimized.
Since the evaluation of BOPs is a local operation within a
finite environment, the parallelization concepts known from
short-range interacting particle simulations can be applied
to improve the performance of these simulations. In this
work, several efficient parallelization methods for BOPs
that use three-dimensional domain decomposition schemes are
described. The schemes are implemented into the bond-order
potential code BOPfox, and their performance is measured in
a series of benchmarks. Systems of up to several millions of
atoms are simulated on a high performance computing system,
and parallel scaling is demonstrated for up to thousands of
processors.},
