The OpenCL library file provided on Galaxy Note 3 does expose the Krait CPU. We were able to query the device for OpenCL platform/device properties. You can also check the CPU device capability using the OpenCL Info app(https://play.google.com/store/apps/details?id=com.xh.openclinfo) we posted in the above blog. I assume you have CL programming experience on desktop. You do not need Adreno SDK to develop CL apps if you are already aware of development process using Android NDK. In any case, you can always use our recent post (http://sandbox.arrayfire.com/getting-started-with-opencl-on-android) as reference for developing OpenCL applications for Android.
