If the {neigh/thread} keyword is set to {off}, then the KOKKOS package
threads only over atoms. However, for small systems, this may not expose
enough parallelism to keep a GPU busy. When this keyword is set to {on},
the KOKKOS package threads over both atoms and neighbors of atoms.
Using {neigh/thread} {on} may be slower for large systems, so this this
option is turned on by default only when there are 16K atoms or less
owned by an MPI rank.
the KOKKOS package threads over both atoms and neighbors of atoms. When
using {neigh/thread} {on}, a full neighbor list must also be used. Using
{neigh/thread} {on} may be slower for large systems, so this this option
is turned on by default only when there are 16K atoms or less owned by
an MPI rank and when using a full neighbor list. Not all KOKKOS-enabled
potentials support this keyword yet, and only thread over atoms. Many
simple pair-wise potentials such as Lennard-Jones do support threading
over both atoms and neighbors.
The {newton} keyword sets the Newton flags for pairwise and bonded
interactions to {off} or {on}, the same as the "newton"_newton.html
