Data will stay on the GPU until a timestep where a non-GPU-ized fix or
compute is invoked. Whenever a non-GPU operation occurs (fix,
compute, output), data automatically moves back to the CPU as needed.

+4. Packages
+
+LAMMPS includes many optional packages, which are groups of files that
+enable a specific set of features. For example, force fields for
+molecular systems or granular systems are in packages. You can see
+the list of all packages by typing "make package" from within the src
+directory of the LAMMPS distribution.
+
+See this section of the manual for
+details on how to include/exclude specific packages as part of the
+LAMMPS build process, and for more details about the differences
+between standard packages and user packages in LAMMPS.
+
+Below, the packages currently availabe in LAMMPS are listed. For
+standard packages, just a one-line description is given. For user
+packages, more details are provided.
