<li><p>PRRTE has taken some steps towards Reproducible Builds
(<a class="reference external" href="https://reproducible-builds.org/">https://reproducible-builds.org/</a>). Specifically, PRRTE’s
<code class="docutils literal notranslate"><span class="pre">configure</span></code> and <code class="docutils literal notranslate"><span class="pre">make</span></code> process, by default, records the build
date and some system-specific information such as the hostname where
PRRTE was built and the username who built it. If you desire a
Reproducible Build, set the <code class="docutils literal notranslate"><span class="pre">$SOURCE_DATE_EPOCH</span></code>, <code class="docutils literal notranslate"><span class="pre">$USER</span></code> and
<code class="docutils literal notranslate"><span class="pre">$HOSTNAME</span></code> environment variables before invoking <code class="docutils literal notranslate"><span class="pre">configure</span></code>
and <code class="docutils literal notranslate"><span class="pre">make</span></code>, and PRRTE will use those values instead of invoking
<code class="docutils literal notranslate"><span class="pre">whoami</span></code> and/or <code class="docutils literal notranslate"><span class="pre">hostname</span></code>, respectively. See
<a class="reference external" href="https://reproducible-builds.org/docs/source-date-epoch/">https://reproducible-builds.org/docs/source-date-epoch/</a> for
information on the expected format and content of the
<code class="docutils literal notranslate"><span class="pre">$SOURCE_DATE_EPOCH</span></code> variable.</p></li>
