title: correct way to run a sample CUDA application?
body: <p>I am trying to launch the sample cuda application <code>vectorAdd</code> on Ubuntu 16.04 ARM. I go to the directory with <code>.cu</code> file and run <code>sudo make</code> followed by <code>./vectorAdd</code>. The result is </p>
  
  <pre><code>[Vector addition of 50000 elements]
  Copy input data from host memory to CUDA device
  CUDA kernel launch with 196 blocks and 256 threads
  Copy output data from CUDA device to the host memory
  Test PASSED
  Done 
  </code></pre>
  
  <p>Is this the correct way to run this application? If yes, why am I unable to input two sample vectors data and see the output like in regular C or C++ programs? Any help is greatly appreciated.</p>
