<p>Hallo Carsten,</p>
<p><br></p>
<p>Dienstag, 18. März 2008, meintest Du:</p>

<p><span class=rvts6>CA> Hi John,</span></p>

<p><br></p>
<p><br></p>
<p><span class=rvts6>CA> Sorry, I came up with this question because when compiling 2.6.24.3 </span></p>
<p><span class=rvts6>CA> (linux kernel) I came across these lines:</span></p>
<p><br></p>
<p><span class=rvts6>CA> For x86_64 this is recommended on all multiprocessor Opteron systems. </span></p>
<p><span class=rvts6>CA> </span></p>
<p><br></p>
<p><span class=rvts6>CA> If the system is EM64T, you should say N unless your system is </span></p>
<p><span class=rvts6>CA> </span></p>
<p><span class=rvts6>CA> EM64T NUMA.</span></p>
<p><br></p>
<p><span class=rvts6>CA> Therefore the question if our Xeon E5345 or Xeon X3220 are EM64T NUMA or</span></p>
<p><span class=rvts6>CA> just EM64T.</span></p>
<p><br></p>
<p><span class=rvts6>CA> Sorry for not being more clear initially.</span></p>
<p><br></p>
<p>Could it be that there is already code for the upcoming Nehalem CPU in the kernel? Is intel maybe providing code? I asked a few people who have good knowledge about technologies and linux and this was the only explanation that came up.</p>
<p><br></p>
<p>Cheers, Jan </p>
