<div>&gt; I&#39;m using hwloc-1.3a1r3606.  Now hwloc_get_last_cpu_location() works well:<br>
&gt;<br>
&gt; thread 0  bind:  0x00000008   as core number 3<br>
&gt; thread 1 bind: 0x00000800 as core number 11<br>
<br>
</div>Good.<br>
<div><br>
&gt; but hwloc_linux_get_tid_cpubind() has still some problems because after binding<br>
&gt; one thread on just one core it give me:<br>
&gt;<br>
&gt; thread 0 bind:  0x00000008   as core number 3<br>
&gt; thread 1 bind: &quot;0x00ffffff&quot;  as all available cores!!<br>
<br>
</div>How do you use it exactly?<br>
