This package implements GPU optimizations of various LAMMPS styles. This package uses an external library in lib/gpu which must be compiled before making LAMMPS. See the lib/gpu/README file and the LAMMPS manual for information on building LAMMPS with external libraries. The settings in the Makefile.lammps file in that directory must be correct for LAMMPS to build correctly with this package installed. The people who created this package are Mike Brown (while at Sandia and ORNL) and Trung Nguyen (while at ORNL).
