<h3>Zusammenfassung</h3>

    <div class="warning"><h3>Warnung</h3>
      <p>Dieses MPM ist noch experimentell und funktioniert möglicherweise
        nicht wie erwartet.</p>
    </div>
    
    <p>Dies ist eine experimentelle Variante des Standard-MPMs
      <code class="module"><a href="../mod/worker.html">worker</a></code>. Das Modul verwendet ein 
      Leader/Followers-Design-Pattern, um die Arbeit zwischen Threads zu
      koordinieren. Weitere Informationen finden Sie unter <a href="http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf">http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf</a>.</p>

    <p>Um bei der Erstellung  des <code class="program"><a href="../programs/httpd.html">httpd</a></code> das MPM
      <code class="module"><a href="../mod/leader.html">leader</a></code> zu verwenden, fügen Sie den Argumenten
      des <code class="program"><a href="../programs/configure.html">configure</a></code>-Skripts <code>--with-mpm=leader</code>
      hinzu.</p>
  
    <p>Dieses MPM baut auf den atomaren APR-Vergleichs- und -Tauschoperationen
      für die Thread-Synchronisation auf. Wenn Sie für einen
      x86-Rechner kompilieren, ohne dass 386-Unterstützung benötigt
      wird, oder wenn Sie für einen SPARC-Rechner kompilieren und keine
      pre-UltraSPARC-Chips betreiben müssen, fügen Sie den Argumenten
      des <code class="program"><a href="../programs/configure.html">configure</a></code>-Skripts
      <code>--enable-nonportable-atomics=yes</code> hinzu. Dies veranlasst die
      APR veranlasst dazu, atomare Operationen einzusetzen, welche effizienten
      Befehlscode verwenden, der älteren CPUs nicht zur Verfügung
      stehen.</p>
