<h1><span class="section-number">11.2. </span>Networking support<a class="headerlink" href="#networking-support" title="Permalink to this heading"></a></h1>
<p>Open MPI supports a variety of different networking transports for
off-node communication. Not all transports are supported or available
on every platform. Many require specialized hardware, operating
system drivers, and/or userspace network transport libraries.</p>
<p>When Open MPI is being configured, it will search for a variety of
network transport libraries (and corresponding development header
files). By default, if <code class="docutils literal notranslate"><span class="pre">configure</span></code> can find a network transport
library and its development header files, it will include support for
that library. If <code class="docutils literal notranslate"><span class="pre">configure</span></code> does not find a library or its header
files, it will simply skip that library (and Open MPI will simply not
build support for that library).</p>
