			<h1>4. Packages</h1>
			<p>This section gives an overview of the add-on optional packages that
			extend LAMMPS functionality. Packages 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.</p>
			<p>Here are links for two tables below, which list standard and user
			packages.</p>
			<div class="line-block">
			<div class="line">4.1 <a class="reference internal" href="#pkg-1"><span class="std std-ref">Standard packages</span></a></div>
			<div class="line">4.2 <a class="reference internal" href="#pkg-2"><span class="std std-ref">User packages</span></a></div>
			<div class="line"><br /></div>
			</div>
			<p><a class="reference internal" href="Section_start.html#start-3"><span class="std std-ref">Section_start 3</span></a> of the manual describes
			the difference between standard packages and user packages. It also
			has general details on how to include/exclude specific packages as
			part of the LAMMPS build process, and on how to build auxiliary
			libraries or modify a machine Makefile if a package requires it.</p>
			<p>Following the two tables below, is a sub-section for each package. It
			has a summary of what the package contains. It has specific
			instructions on how to install it, build or obtain any auxiliary
			library it requires, and any Makefile.machine changes it requires. It
			also lists pointers to examples of its use or documentation provided
			in the LAMMPS distribution. If you want to know the complete list of
			commands that a package adds to LAMMPS, simply list the files in its
			directory, e.g. “ls src/GRANULAR”. Source files with names that start
			with compute, fix, pair, bond, etc correspond to command styles with
			the same names.</p>
			<div class="admonition note">
			<p class="first admonition-title">Note</p>
			<p class="last">The USER package sub-sections below are still being filled in,
			as of March 2016.</p>
			</div>
			<p>Unless otherwise noted below, every package is independent of all the
			others. I.e. any package can be included or excluded in a LAMMPS
			build, independent of all other packages. However, note that some
			packages include commands derived from commands in other packages. If
			the other package is not installed, the derived command from the new
			package will also not be installed when you include the new one.
			E.g. the pair lj/cut/coul/long/omp command from the USER-OMP package
			will not be installed as part of the USER-OMP package if the KSPACE
			package is not also installed, since it contains the pair
			lj/cut/coul/long command. If you later install the KSPACE package and
			the USER-OMP package is already installed, both the pair
			lj/cut/coul/long and lj/cut/coul/long/omp commands will be installed.</p>

			<p>The “Authors” column lists a name(s) if a specific person is
			responible for creating and maintaining the package.</p>
			<p>(1) The COLLOID package includes Fast Lubrication Dynamics pair styles
			which were created by Amit Kumar and Michael Bybee from Jonathan
			Higdon’s group at UIUC.</p>
			<p>(2) The OPT package was created by James Fischer (High Performance
			Technologies), David Richie, and Vincent Natoli (Stone Ridge
			Technolgy).</p>
			<p>(3) The KIM package was created by Valeriu Smirichinski, Ryan Elliott,
			and Ellad Tadmor (U Minn).</p>
			<p>(4) The KOKKOS package was created primarily by Christian Trott and
			Stan Moore (Sandia). It uses the Kokkos library which was developed
			by Carter Edwards, Christian Trott, and others at Sandia.</p>
			<p>The “Doc page” column links to either a sub-section of the
			<a class="reference internal" href="Section_howto.html"><span class="doc">Section_howto</span></a> of the manual, or an input script
			command implemented as part of the package, or to additional
			documentation provided within the package.</p>
			<p>The “Example” column is a sub-directory in the examples directory of
			the distribution which has an input script that uses the package.
			E.g. “peptide” refers to the examples/peptide directory.</p>
			<p>The “Library” column lists an external library which must be built
			first and which LAMMPS links to when it is built. If it is listed as
			lib/package, then the code for the library is under the lib directory
			of the LAMMPS distribution. See the lib/package/README file for info
			on how to build the library. If it is not listed as lib/package, then
			it is a third-party library not included in the LAMMPS distribution.
			See details on all of this below for individual packages.

			<p>Contents: Dozens of pair styles and a version of the PPPM long-range
			Coulombic solver for NVIDIA GPUs. All of them have a “gpu” in their
			style name. <a class="reference internal" href="accelerate_gpu.html"><span class="doc">Section accelerate gpu</span></a> gives
			details of what hardware and Cuda software is required on your system,
			and how to build and use this package. See the KOKKOS package, which
			also has GPU-enabled styles.</p>
			<p>Building LAMMPS with the GPU package requires first building the GPU
			library itself, which is a set of C and Cuda files in lib/gpu.
			Details of how to do this are in lib/gpu/README. As illustrated
			below, perform a “make” using one of the Makefile.machine files in
			lib/gpu which should create a lib/reax/libgpu.a file.
			Makefile.linux.* and Makefile.xk7 are examples for different
			platforms. There are 3 important settings in the Makefile.machine you
			use:</p>
			<ul class="simple">
			<li>CUDA_HOME = where NVIDIA Cuda software is installed on your system</li>
			<li>CUDA_ARCH = appropriate to your GPU hardware</li>
			<li>CUDA_PREC = precision (double, mixed, single) you desire</li>
			</ul>
			<p>See example Makefile.machine files in lib/gpu for the syntax of these
			settings. See lib/gpu/Makefile.linux.double for ARCH settings for
			various NVIDIA GPUs. The “make” also creates a
			lib/gpu/Makefile.lammps file. This file has settings that enable
			LAMMPS to link with Cuda libraries. If the settings in
			Makefile.lammps for your machine are not correct, the LAMMPS link will
			fail. Note that the Make.py script has a “-gpu” option to allow the
			GPU library (with several of its options) and LAMMPS to be built in
			one step, with Type “python src/Make.py -h -gpu” to see the details.</p>

			<p>Contents: Dozens of atom, pair, bond, angle, dihedral, improper styles
			which run with the Kokkos library to provide optimization for
			multicore CPUs (via OpenMP), NVIDIA GPUs, or the Intel Xeon Phi (in
			native mode). All of them have a “kk” in their style name. <a class="reference internal" href="accelerate_kokkos.html"><span class="doc">Section accelerate kokkos</span></a> gives details of what
			hardware and software is required on your system, and how to build and
			use this package. See the GPU, OPT, USER-INTEL, USER-OMP packages,
			which also provide optimizations for the same range of hardware.</p>
			<p>Building with the KOKKOS package requires choosing which of 3 hardware
			options you are optimizing for: CPU acceleration via OpenMP, GPU
			acceleration, or Intel Xeon Phi. (You can build multiple times to
			create LAMMPS executables for different hardware.) It also requires a
			C++11 compatible compiler. For GPUs, the NVIDIA “nvcc” compiler is
			used, and an appopriate KOKKOS_ARCH setting should be made in your
			Makefile.machine for your GPU hardware and NVIDIA software.</p>
			<p>The simplest way to do this is to use Makefile.kokkos_cuda or
			Makefile.kokkos_omp or Makefile.kokkos_phi in src/MAKE/OPTIONS, via
			“make kokkos_cuda” or “make kokkos_omp” or “make kokkos_phi”. (Check
			the KOKKOS_ARCH setting in Makefile.kokkos_cuda), Or, as illustrated
			below, you can use the Make.py script with its “-kokkos” option to
			choose which hardware to build for. Type “python src/Make.py -h
			-kokkos” to see the details. If these methods do not work on your
			system, you will need to read the <a class="reference internal" href="accelerate_kokkos.html"><span class="doc">Section accelerate kokkos</span></a> doc page for details of what

			<p>Building LAMMPS with the MEAM package requires first building the MEAM
			library itself, which is a set of Fortran 95 files in lib/meam.
			Details of how to do this are in lib/meam/README. As illustrated
			below, perform a “make” using one of the Makefile.machine files in
			lib/meam which should create a lib/meam/libmeam.a file.
			Makefile.gfortran and Makefile.ifort are examples for the GNU Fortran
			and Intel Fortran compilers. The “make” also copies a
			lib/meam/Makefile.lammps.machine file to lib/meam/Makefile.lammps.
			This file has settings that enable the C++ compiler used to build
			LAMMPS to link with a Fortran library (typically the 2 compilers to be
			consistent e.g. both Intel compilers, or both GNU compilers). If the
			settings in Makefile.lammps for your compilers and machine are not
			correct, the LAMMPS link will fail. Note that the Make.py script has
			a “-meam” option to allow the MEAM library and LAMMPS to be built in
			one step. Type “python src/Make.py -h -meam” to see the details.</p>

			<p>To build LAMMPS with the KIM package you must have previously
			installed the KIM API (library) on your system. The lib/kim/README
			file explains how to download and install KIM. Building with the KIM
			package also uses the lib/kim/Makefile.lammps file in the compile/link
			process. You should not need to edit this file.</p>
			<p>To build LAMMPS with the VORONOI package you must have previously
			installed the Voro++ library on your system. The lib/voronoi/README
			file explains how to download and install Voro++. There is a
			lib/voronoi/install.py script which automates the process. Type
			“python install.py” to see instructions. The final step is to create
			soft links in the lib/voronoi directory for “includelink” and
			“liblink” which point to installed Voro++ directories. Building with
			the VORONOI package uses the contents of the
			lib/voronoi/Makefile.lammps file in the compile/link process. You
			should not need to edit this file. Note that the Make.py script has a
			“-voronoi” option to allow the Voro++ library to be downloaded and/or
			installed and LAMMPS to be built in one step. Type “python
			src/Make.py -h -voronoi” to see the details.</p>

			<p>Supporting info:</p>
			<p>This package provides a fix qmmm command which allows LAMMPS to be
			used in a QM/MM simulation, currently only in combination with pw.x
			code from the <a class="reference external" href="http://www.quantum-espresso.org">Quantum ESPRESSO</a> package.</p>
			<p>The current implementation only supports an ONIOM style mechanical
			coupling to the Quantum ESPRESSO plane wave DFT package.
			Electrostatic coupling is in preparation and the interface has been
			written in a manner that coupling to other QM codes should be possible
			without changes to LAMMPS itself.</p>

			<span id="user-reaxc"></span><h3>4.2.22. USER-REAXC package</h3>
			<p>Supporting info:</p>
			<p>This package contains a implementation for LAMMPS of the ReaxFF force
			field. ReaxFF uses distance-dependent bond-order functions to
			represent the contributions of chemical bonding to the potential
			energy. It was originally developed by Adri van Duin and the Goddard
			group at CalTech.</p>
			<p>The USER-REAXC version of ReaxFF (pair_style reax/c), implemented in
			C, should give identical or very similar results to pair_style reax,
			which is a ReaxFF implementation on top of a Fortran library, a
			version of which library was originally authored by Adri van Duin.</p>
			<p>The reax/c version should be somewhat faster and more scalable,
			particularly with respect to the charge equilibration calculation. It
			should also be easier to build and use since there are no complicating
			issues with Fortran memory allocation or linking to a Fortran library.</p>
			<p>For technical details about this implemention of ReaxFF, see
			this paper:</p>
			<p>Parallel and Scalable Reactive Molecular Dynamics: Numerical Methods
			and Algorithmic Techniques, H. M. Aktulga, J. C. Fogarty,
			S. A. Pandit, A. Y. Grama, Parallel Computing, in press (2011).</p>
			<p>See the doc page for the pair_style reax/c command for details
			of how to use it in LAMMPS.</p>

			at lbl.gov), while at Purdue University. Contact him directly, or
			Aidan Thompson at Sandia (athomps at sandia.gov), if you have
