<section id="resolving-the-not-found-dependency-errors">
<h3>Resolving the ‘not found’ dependency errors<a class="headerlink" href="#resolving-the-not-found-dependency-errors" title="Link to this heading">¶</a></h3>
<p>Assuming all the <a class="reference internal" href="#dependency-installation"><span class="std std-ref">dependencies</span></a> have been
correctly installed, one or more might still appear with the ‘not found’ status upon
configuring with the <code class="docutils literal notranslate"><span class="pre">cmake</span></code> command (see above). In this case, you will
need to find the ‘non-standard’ location for each missing dependency
(most often a shared or dynamically loaded library, e.g.
<code class="docutils literal notranslate"><span class="pre">libgromacs.so.*</span></code>, <code class="docutils literal notranslate"><span class="pre">libhdf5.so.*</span></code> etc).</p>
<p>Error messages produced by CMake usually provide instructive suggestions
for resolving dependency issues. In particular, an appropriate extra
<code class="docutils literal notranslate"><span class="pre">-D</span></code> flag is necessary to specify the path to a missed package. You
will have to rerun the <code class="docutils literal notranslate"><span class="pre">cmake</span></code> command with the relevant flag(s)
added. For example, in the case of a locally installed version of
GROMACS:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>cmake -DCMAKE_INSTALL_PREFIX=${prefix} -DGROMACS_INCLUDE_DIR=$HOME/gromacs/include -DGROMACS_LIBRARY=$HOME/gromacs/lib/libgromacs.so -S ..
</pre></div>
</div>
<p>Please also ensure GROMACS was build with <code class="docutils literal notranslate"><span class="pre">-DGMX_INSTALL_LEGACY_API=ON</span></code>.</p>
<p>Be careful to use exactly the option suggested in the error message! You
can also add <code class="docutils literal notranslate"><span class="pre">-LH</span></code> or <code class="docutils literal notranslate"><span class="pre">-LAH</span></code> options to the <code class="docutils literal notranslate"><span class="pre">cmake</span></code> command in
order to see the available options with brief explanations (note that
<em>changing some of the variables may result in more variables being
created</em>; run <code class="docutils literal notranslate"><span class="pre">man</span> <span class="pre">cmake</span></code> for more info).</p>
<p><em>Only for Linux</em>: For each dependency package not found by CMake
initially, it might be necessary to add the location of its <code class="docutils literal notranslate"><span class="pre">lib</span></code>
directory to the environment variable <code class="docutils literal notranslate"><span class="pre">LD_LIBRARY_PATH</span></code>, <strong>before</strong>
building and installing VOTCA, i.e. before running any <code class="docutils literal notranslate"><span class="pre">make</span></code> command.
For example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/gromacs/lib:$HOME/anaconda/lib
</pre></div>
</div>
<p>Note that <code class="docutils literal notranslate"><span class="pre">LD_LIBRARY_PATH</span></code> also needs to be set every time when
running an executable from the VOTCA installation afterwards (which can
be automated via the user’s login profile, e.g. in .bashrc). Alternatively,
CMake has options to <em>remember</em> where libraries came from at link time,
which can be enabled by setting <code class="docutils literal notranslate"><span class="pre">CMAKE_INSTALL_RPATH_USE_LINK_PATH</span></code> to
<code class="docutils literal notranslate"><span class="pre">ON</span></code>. VOTCA has enabled this option and a couple of other rpath
related tweaks when setting <code class="docutils literal notranslate"><span class="pre">ENABLE_RPATH_INJECT</span></code> to <code class="docutils literal notranslate"><span class="pre">ON</span></code>.</p>

<section id="performance-advice">
<h3>Performance advice<a class="headerlink" href="#performance-advice" title="Link to this heading">¶</a></h3>
<p>VOTCA-XTP relies on the Eigen library for vector-matrix operations, and a lot of
performance can be gained by enabling vectorization and/or use of Intel’s <code class="docutils literal notranslate"><span class="pre">MKL</span></code>
as backend, which is automatically detected by <code class="docutils literal notranslate"><span class="pre">CMake</span></code>. Below are some recommendations
for different architectures:</p>
<section id="intel-processors">
<h4>Intel Processors<a class="headerlink" href="#intel-processors" title="Link to this heading">¶</a></h4>
<p><code class="docutils literal notranslate"><span class="pre">g++</span></code>, <code class="docutils literal notranslate"><span class="pre">clang</span></code>, and <code class="docutils literal notranslate"><span class="pre">ipcx</span></code> from the Intel OneAPI basekit give similar performance
when used with the MKL. No special flags have to be supplied to <code class="docutils literal notranslate"><span class="pre">CMake</span></code>.</p>
<p>If <code class="docutils literal notranslate"><span class="pre">g++</span></code> or <code class="docutils literal notranslate"><span class="pre">clang</span></code> are used, the compiler option <code class="docutils literal notranslate"><span class="pre">-march=native</span></code> is automatically injected
into the build. If you compile VOTCA on a heterogeneous cluster with different instruction sets,
this may cause the executables to not run. Override this by specifying
<code class="docutils literal notranslate"><span class="pre">-DCMAKE_CXX_FLAGS=-mtune=native</span></code> (at probably lower performance), or perform node-type
specific builds.</p>
<p>As a rough estimate, runtimes with vectorization and <code class="docutils literal notranslate"><span class="pre">gcc/clang</span></code> are 30% shorter than without
vectorization. Use of <code class="docutils literal notranslate"><span class="pre">MKL</span></code> reduces them by another 50%.</p>
</section>
<section id="amd-processors">
<h4>AMD Processors<a class="headerlink" href="#amd-processors" title="Link to this heading">¶</a></h4>
<p>We recommend using <code class="docutils literal notranslate"><span class="pre">g++</span></code> or <code class="docutils literal notranslate"><span class="pre">clang</span></code> rather than an Intel compiler on AMD. Vectorization
in <code class="docutils literal notranslate"><span class="pre">Eigen</span></code> is automatically enabled by injection of <code class="docutils literal notranslate"><span class="pre">-march=native</span></code>. See above comment
about heterogeneous envionments.</p>
<p>If you have Intel’s MKL installed, and it is found by <code class="docutils literal notranslate"><span class="pre">CMake</span></code>, performance will be helped
but by how much idepends on which architecture-specific implementation MKL picks at runtime.
This can be affected by a <a class="reference external" href="https://en.wikipedia.org/wiki/Math_Kernel_Library">vendor lock-in</a>,
and work-arounds are documented <a class="reference external" href="https://danieldk.eu/Posts/2020-08-31-MKL-Zen.html">for Intel MKL on AMD Zen</a>

We advise that you test this on your specific architecture.</p>

<h2>Linking Error: Undefined reference to<a class="headerlink" href="#linking-error-undefined-reference-to" title="Link to this heading">¶</a></h2>
<p>This error can occur for a multitude of reasons. You may have
forgotten to add paths to the <code class="docutils literal notranslate"><span class="pre">LD_LIBRARY_PATH</span></code> or forgotten to import
an environment module. In these cases, deleting the <code class="docutils literal notranslate"><span class="pre">CMakeCache.txt</span></code> in
your <code class="docutils literal notranslate"><span class="pre">build</span></code> folder and rerunning <code class="docutils literal notranslate"><span class="pre">cmake</span></code> will help. Unfortunately,
another cause might be ABI incompability between libraries due to
different libraries being compiled with different compilers or compiler
versions. Click <a class="reference external" href="https://github.com/ICRAR/shark/issues/1">here</a> for
an example.</p>
