Further reading hinted at the lack of OpenCL 1.2 on Nvidia graphics cards.
The clinfo package for Ubuntu doesn't recognize my GPU for the same reason.
I checked their official website at
http://www.geforce.com/hardware/notebook-gpus/geforce-gt-730m/specifications
Sure enough only OpenCL 1.1 is listed. How do I move forward?
Thanks,
