/* ERROR/WARNING messages:
E: Cannot use fix GPU with USER-CUDA mode enabled
You cannot use both the GPU and USER-CUDA packages
together. Use one or the other.
E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
E: Cannot use force/neigh with triclinic box
This is a current limitation of the GPU implementation
in LAMMPS.
E: Cannot use force/hybrid_neigh with triclinic box
Self-explanatory.
E: No OpenMP support compiled in
An OpenMP flag is set, but LAMMPS was not built with
OpenMP support.
E: GPU package does not (yet) work with atom_style template
Self-explanatory.
E: Cannot use pair hybrid with GPU neighbor list builds
Neighbor list builds must be done on the CPU for this pair style.
E: GPU split param must be positive for hybrid pair styles
See the package gpu command.
E: Cannot use neigh_modify exclude with GPU neighbor builds
This is a current limitation of the GPU implementation
in LAMMPS.
