            <title>[DOCS-3505] NUMA notes should note discussion is moot for 1 physical processor</title>
                <link>https://jira.mongodb.org/browse/DOCS-3505</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;&lt;a href=&quot;http://docs.mongodb.org/manual/administration/production-notes/#mongodb-and-numa-hardware&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/administration/production-notes/#mongodb-and-numa-hardware&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;It seems some people are getting confused about the NUMA guidelines when they have exactly one physical processor, in which case the discussion is  moot.&lt;/p&gt;

&lt;p&gt;Examples of confusion:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-13900&quot; title=&quot;Numactl use in Ubuntu upstart script should check the number of nodes&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-13900&quot;&gt;&lt;del&gt;SERVER-13900&lt;/del&gt;&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://groups.google.com/forum/#!topic/mongodb-dev/Ok6ySvnCltE&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://groups.google.com/forum/#!topic/mongodb-dev/Ok6ySvnCltE&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;With a single physical processor, it doesn&apos;t matter whether you use &quot;numactl --interleave=all&quot; or not.&lt;/p&gt;

&lt;p&gt;NUMA settings only matter with &amp;gt; 1 physical processor.&lt;/p&gt;</description>
