<h3>Summary</h3>
<div class="warning"><h3>Warning</h3>
<p>This MPM is experimental, so it may or may not work
as expected.</p>
</div>
<p>This is an experimental variant of the standard
<code class="module"><a href="/mod/worker.html">worker</a></code> MPM. It uses a Leader/Followers design pattern
to coordinate work among threads. For more info, see <a href="http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf">http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf</a>.</p>
<code>--with-mpm=leader</code> to the <code class="program"><a href="/programs/configure.html">configure</a></code>
script's arguments when building the <code class="program"><a href="/programs/httpd.html">httpd</a></code>.</p>
<p>This MPM depends on APR's atomic compare-and-swap operations for
thread synchronization. If you are compiling for an x86 target
and you don't need to support 386s, or you are compiling for a
SPARC and you don't need to run on pre-UltraSPARC chips, add
<code>--enable-nonportable-atomics=yes</code> to the
<code class="program"><a href="/programs/configure.html">configure</a></code> script's arguments. This will cause
APR to implement atomic operations
using efficient opcodes not available in older CPUs.</p>
