  <p>RenderScript exposes a set of compute APIs that you can use to do intensive computational operations.
  You can use the compute APIs in the context of a graphics RenderScript such as calculating the
  transformation of many geometric objects in a scene. You can also create a standalone compute RenderScript that does not
  draw anything to the screen such as bitmap image processing for a photo editor application.
  The RenderScript compute APIs are mainly defined in the <code>rs_cl.rsh</code> header</p>
  
  <p>Compute RenderScripts are simpler to setup and implement as there is no graphics rendering involved.
  You can offload computational aspects of your application to RenderScript by creating a native RenderScript
  file (.rs) and using the generated reflected layer class to call functions in the <code>.rs</code> file.

  sample in the Android SDK for more
  information on how to create a simple compute RenderScript.</p>
