title: Does CUDA applications' compute capability automatically upgrade?
body: <p>If I compile a CUDA program with a lower Compute Capability, e.g 1.3 (nvcc flag sm_13), and run it on a device with Compute Capability 2.1, will it exploit the features of Compute 2.1 or  not?</p>
  
  <p>In that situation, Will the compute 2.1 device behave like a compute 1.3 device?</p>
