title: OpenCL dynamic parallelism / GPU-spawned threads?
body: <p>CUDA 5 <a href="http://nvidianews.nvidia.com/Releases/NVIDIA-Releases-CUDA-5-Making-Programming-With-World-s-Most-Pervasive-Parallel-Computing-Platform-Even-Easier-88b.aspx" rel="nofollow">has just been released</a> and with it the ability to spawn GPU threads from within another GPU (main?) thread, minimising callouts between CPU and GPU that we've seen thus far.</p>
  
  <p>What plans are there to support GPU-spawned threads in the OpenCL arena? As I cannot afford to opt for a closed standard (my user base is "everygamer"), I need to know when OpenCL is ready for prime time in this regard.</p>
