Hi,<br>
<br>
I have been doing some experiments with the -threads options. I am
using CBC on Windows and v.2.9.0 which I have recompiled following
the steps described in <a href="http://list.coin-or.org/pipermail/cbc/2012-October/000894.html" target="_blank">http://list.coin-or.org/pipermail/cbc/2012-October/000894.html</a><br>
<br>
On my test problems, I have not seen really any improvement in terms
of resolution time. Also, when I am looking at the CPU usage on the
Task Manager, the impact of using this option is not obvious.<br>
<br>
Has anybody had a similar experience? Or has somebody done some
performance tests?<br>
<br>
Thanks in advance<span class="HOEnZb"><font color="#888888"><br>
