title: Install CUDA-7.5 on a computer using GTX950 and Tesla K40
body: <p>I'm trying to do install CUDA-7.5 on Ubuntu 14.04, And I have both GTX950 and Tesla K40 inserted in my motherboard.</p>
  
  <p>and the <strong><em>lspci | grep -i nvidia</em></strong> command gives the following result:</p>
  
  <pre><code>01:00.0 3D controlloer: NVIDIA Corporation GK110BGL [Tesla K40c] (rev a1)
  02:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForece GTX 950] (rev a1)
  02:00.1 Audio device: NVIDIA Corporation Device 0fba (rev a1)
  </code></pre>
  
  <p>I think I have successfully installed CUDA-7.5 on my computer, because I can actually run <strong><em>./smokeParticles</em></strong> sample in <strong>NVIDIA_CUDA-7.5_Samples/bin/x86_64/linux/release/</strong>.</p>
  
  <p>But I have one question: </p>
  
  <ul>
  <li>How can I be sure that I'm actually using Tesla K40? Because the <strong><em>./smokeParticles</em></strong> sample is also successful after I unplug the 
  Tesla K40 form my motherboard. (I assume that GTX 950 is running the sample...)</li>
  </ul>
  
  <p>Is there a command or something that can tell me I'm using Tesla K40?</p>
