Not yet. There are details to handle.

Probably.

This is DEBUG information. Please let me know what you guys expect. For 
example (please look close to the details, since i don't know how to 
format text here):

OpenCL platform 0: Apple, 2 device(s).
* Device 0: Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz (In use)
   Device 1: GeForce GT 650M

> It's a good thing the OpenCL header only appears once and it's probably sane to have it right at the top. But then I'm not sure about the "Using device" lines. It should probably appear before the first OpenCL format just like it does, but then it should not be repeated. Or should it? I'm not sure.

Discuss and pick whatever you want:

OpenCL platform 0: Apple, 2 device(s).
* Device 0: Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz (In use)
   Device 1: GeForce GT 650M

or

OpenCL platform 0: Apple, 2 device(s).
   Device 0: Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz (In use)
   Device 1: GeForce GT 650M

or

OpenCL platform 0: Apple, 2 device(s).
   Using device 0: Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz
   Device 1: GeForce GT 650M
