&gt; Hi all,<br>
&gt;<br>
&gt; Per my understanding, the &quot;processor&quot; in &quot;SMP&quot; and &quot;UP&quot; should be a<br>
&gt; &quot;logic CPU&quot;, not a &quot;physical CPU&quot;.<br>
&gt; If the &quot;physical CPU&quot; contains 2 &quot;cores&quot;, and every &quot;core&quot; contains 2<br>
&gt; &quot;hardware threads&quot;, then the &quot;processor&quot;<br>
&gt; should stands for &quot;hardware thread&quot;.<br>
&gt;<br>
&gt; Is my understanding right? Thanks very much in advance!<br>
<br>
</span>Yes, you are absolutely right, when speaking from a<br>
software point of view.<br>
<br>
Each logical processor shows up as a CPU in Linux.<br>
<br>
Of course, if you were to talk to somebody installing<br>
physical CPUs in systems, you would get a different<br>
answer :)<br>
