The {neigh} keyword determines how neighbor lists are built. A value of 

{half} uses a thread-safe variant of half-neighbor lists, the same as 

used by most pair styles in LAMMPS, which is the default when running on 

CPUs (i.e. CUDA backend not enabled). 

CPUs (i.e. the Kokkos CUDA back end is not enabled). 

A value of {full} uses a full neighbor lists and is the default when 

running on GPUs. This performs twice as much computation as the {half}
