The keyword *chunksize* is only applicable when using the
KOKKOS package and is ignored otherwise. This keyword controls
the number of atoms in each pass used to compute the forces
and is use to avoid running out of memory. For example if there
are 4000 atoms in the simulation and the *chunksize* is set to
2000, the force calculation will be broken up into two passes.
