Configuring Tensorflow to use all CPU's : <p>Reading : 
<a href="https://www.tensorflow.org/versions/r0.10/resources/faq.html" rel="noreferrer">https://www.tensorflow.org/versions/r0.10/resources/faq.html</a> it states : </p>

<blockquote>
  <p>Does TensorFlow make use of all the devices (GPUs and CPUs) available
  on my machine?</p>
  
  <p>TensorFlow supports multiple GPUs and CPUs. See the how-to
  documentation on using GPUs with TensorFlow for details of how
  TensorFlow assigns operations to devices, and the CIFAR-10 tutorial
  for an example model that uses multiple GPUs.</p>
  
  <p>Note that TensorFlow only uses GPU devices with a compute capability
  greater than 3.5.</p>
</blockquote>

<p>Does this mean Tensorflow can automatically make use of all CPU's on given machine or does it ned to be explicitly configured ?</p>
