<p><code class="docutils literal notranslate"><span class="pre">opal_wrapper</span></code> is not meant to be called directly by end users. It
is automatically invoked as the back-end by the Open MPI wrapper
commands such as: <code class="docutils literal notranslate"><span class="pre">mpicc</span></code>, <code class="docutils literal notranslate"><span class="pre">mpicxx</span></code>, and <code class="docutils literal notranslate"><span class="pre">mpifort</span></code>
(and its legacy/deprecated aliases <code class="docutils literal notranslate"><span class="pre">mpif77</span></code> and <code class="docutils literal notranslate"><span class="pre">mpif90</span></code>).</p>
<p>Some Open MPI installations may have additional wrapper commands,
and/or have renamed the wrapper compilers listed above to avoid
executable name conflicts with other MPI implementations. Hence, you
may also have wrapper compilers installed including the following
names: <code class="docutils literal notranslate"><span class="pre">mpifort.openmpi</span></code> (and the legacy/deprecated aliases
<code class="docutils literal notranslate"><span class="pre">mpif90.openmpi</span></code> and <code class="docutils literal notranslate"><span class="pre">mpif77.openmpi</span></code>), <code class="docutils literal notranslate"><span class="pre">mpicxx.openmpi</span></code>,
<code class="docutils literal notranslate"><span class="pre">mpicc.openmpi</span></code>.</p>
