title: How do you enumerate all accelerators in C++ AMP?
body: <p>In C++ AMP, how does one detect and enumerate all C++ AMP accelerators?</p>
  
  <p>Don McCrady distributed an app <a href="http://blogs.msdn.com/b/nativeconcurrency/archive/2011/09/22/can-i-run-c-amp-on-my-device.aspx" rel="nofollow">here</a> that enumerates <em>non-emulated</em> accelerators. Though I had a DX11 card (GTX 260), I didn't see any available accelerators. Daniel Moth shows <a href="http://www.danielmoth.com/Blog/concurrencyaccelerator.aspx" rel="nofollow">here</a> how to query an individual accelerator, but I couldn't find how do enumerate all (emulated and non) accelerators using a C++ AMP call.</p>
