<description>An experimental variant of the standard <module>worker</module>
MPM</description>
<status>MPM</status>
<identifier>mpm_leader_module</identifier>
<summary>
<note type="warning"><title>Warning</title>
<p>This MPM is experimental, so it may or may not work
as expected.</p>
</note>
<p>This is an experimental variant of the standard
to coordinate work among threads. For more info, see <a
<p>To use the <module>leader</module> MPM, add
<code>--with-mpm=leader</code> to the <program>configure</program>
script's arguments when building the <program>httpd</program>.</p>
</summary>
<section id="requirements"><title>Requirements</title>
<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
<program>configure</program> script's arguments. This will cause
APR to implement atomic operations
using efficient opcodes not available in older CPUs.</p>
