For some of the simple 2-body potentials without long-range

electrostatics, performance and scalability can be better with

the "newton off" setting added to the input script :l

For simulations on higher node counts, add "processors * * * grid 

numa" to the beginning of the input script for better scalability :l

If using {kspace_style pppm} in the input script, add

"kspace_modify diff ad" for better performance :l

:ule

input script to automatically append the "omp" suffix to styles when

USER-INTEL styles are not available.

NOTE: For simulations on higher node counts, add "processors * * * 

grid numa"_processors.html" to the beginning of the input script for

better scalability.

When running on many nodes, performance might be better when using

fewer OpenMP threads and more MPI tasks. This will depend on the

simulation and the machine. Using the "verlet/split"_run_style.html
