Developing OpenCL apps on iOS without jailbreaking

[kerkilchoi]

Is it generally possible to develop an app that uses OpenCL on iOS (e.g., iPhone 5s) without jailbreaking?

I noticed you imply that you could wrap your project as an Xcode project. Would it allow one to use your code without jailbreaking an iOS device? Would it imply that OpenCL codes can be developed and provided to a device that is not jailbroken?

Thanks.

@kerkilchoi Thanks for your comment. Short answer is that, currently still impossible to run on non-jailbroken devices. Because OpenCL is a private framework which sandboxed apps don't have rights to access. But there is an interesting article introducing how to abuse OpenGL to implement GPGPU. Maybe you can give it a try.

Just to add a comment on this old thread, my experience was that even on the private framework on a jailbroken device, it actually only gave you access to OpenCL on the CPU. This was on the iPhone 4, iOS ... 6? So the slightest chance things have improved, but very unlikely given Metal...
