<h1>LAMMPS-ICMS RPM Repository</h1>
<p align="justify">
This repository is hosting pre-compiled RPM packages of the
<a href="http://lammps.sandia.gov/" target="_blank">LAMMPS</a>
molecular dynamics simulation software package.
The binaries are built using the
<a href="http://goo.gl/oKYI" target="_blank">LAMMPS-ICMS</a>
branch <a href="http://git.icms.temple.edu/git/" target="_blank">git repository</a>.
The packages are configured to depend only on packages that are
part of the respective distributions, so dependencies should be
resolved automatically when using yum to install the packages.
The LAMMPS binaries contain <b>all</b> optional packages included in
the source distribution <b>except</b>: GPU, KIM, KOKKOS, and
USER-CUDA since those depend on libraries that do not exist as
regular RPM packages and/or where the license is incompatible with
including them in a binary distribution like this one. In addition
the Fortran variant of ReaxFF support has been omitted, since this
has been superseded by the C/C++ version in the USER-REAXC package.
The USER-REAXC code has been proven to produce results consistent
with the Fortran version and be faster and more flexible.

<h2>Available Repositories</h2>
<p align="justify">
Binary RPMs are currently provided for up-to-date versions of
<a href="http://www.redhat.com/rhel/" target="_blank">Red Hat Enterprise Linux</a>
or <a href="http://www.centos.org/" target="_blank">CentOS</a>
(version 6.4 at the time of this writing),
<a href="http://fedoraproject.org" target="_blank">Fedora</a>
(versions 17, 18, 19 and 20 at the time of this writing)
and <a href="http://www.opensuse.org/" target="_blank">OpenSuSE</a>
(versions 12.3 and 13.1 as of this writing) for 32-bit (i386/i586) and
64-bit (x86_64) Intel/AMD x86 CPU versions. Binaries for
additional distributions and versions may be added based on demand
and available resources. The packages are provided <b>without
warranty and support</b>. If you notice any problems or would like
to see binaries for other distributions or versions or platforms
made available, you can contact
<a href="http://goo.gl/1wk0" target="_blank">Axel Kohlmeyer</a>
and we can try to find a solution.

<h2>Other RPM-based Distributions</h2>
<p align="justify">
There is a huge number of Linux distributions on a large variety
of hardware around and it is impossible to provide binaries for
all of them, even if they do use the RPM package format. For those
distributions, you can download a source RPM from below and try a
custom RPM build after installing the necessary packages required
for building the binary RPM via the command:</p>
<div style="background-color: #e8e8f0; padding: 10px;">
<code>rpmbuild --rebuild &lt;name of the source rpm file&gt;</code>.<br>
</div>
</p>
<p align="justify">
If your distribution is not simply a different version of the ones
listed above, chances are, that some additional tweaks to the
lammps.spec file are required. You can contact
<a href="http://goo.gl/1wk0" target="_blank">Axel Kohlmeyer</a> to
see, if there is a (simple) solution. But very likely you will be
better off following the
<a href="http://lammps.sandia.gov/doc/Section_start.html" target="_blank">
generic compilation instructions</a> in the LAMMPS manual.
</p>
<ul>
<li>Browse Source RPM <a href="source">repository</a></li>
</ul>
<hr width="100%">
<h2>Non-RPM-based Distributions</h2>
<p align="justify">
For Ubuntu and similar distributions based on the Debian packaging system,
you can use the LAMMPS daily build repository set up by Anton Gladky.
Instructions for accessing it are on the
<a href="http://lammps.sandia.gov/download.html#ubuntu">LAMMPS Download page</a>.
</p>
<p align="justify">
For Gentoo Linux LAMMPS has been integrated by Nicolas Bock and Christoph Junghans
into the portage system and LAMMPS can be configured and installed using the emerge
command. Basinc instructions are on the
<a href="http://lammps.sandia.gov/download.html#gentoo">LAMMPS Download page</a>.
