title: Compiling numpy with OpenBLAS integration
body: <p>I am trying to install <code>numpy</code> with <code>OpenBLAS</code> , however I am at loss as to how the <code>site.cfg</code> file needs to be written. </p>
  
  <p>When the <a href="http://www.kde.cs.tut.ac.jp/~atsushi/?p=493#">installation procedure</a> was followed the installation completed without errors, however there is performance degradation on increasing the number of threads used by OpenBLAS from 1 (controlled by the environment variable OMP_NUM_THREADS).</p>
  
  <p>I am not sure if the OpenBLAS integration has been perfect. Could any one provide a <code>site.cfg</code> file to achieve the same.</p>
  
  <p>P.S.: OpenBLAS integration in other toolkits like <a href="http://deeplearning.net/software/theano/">Theano</a>, which is based on Python, provides substantial performance boost on increasing the number of threads, on the same machine.</p>
