The handy little app “OpenCL Info” lets you check if you have OpenCL installed on your Android device. Developed Xavier Hallade the app is available on the Google store. If you do find it available then let the folks over at ArrayFire know as they have published a Google Document tracking supported devices and are looking for feedback.

From the App Developer:

Even though OpenCL isn't part of the Android platform, it's available on many recent devices.
On Android it's usually used as a back-end for other frameworks like Renderscript.
Some manufacturers are providing SDKs for developers to use OpenCL on Android.
Run this application to know which version of OpenCL™ (if any) can be used on your Android device, and what are its capabilities.

The application has been developed on x86 and ARM devices using PowerVR or Intel® HD Graphics GPUs but it has been designed to also work with others.

If your device is known to have OpenCL™ but the app can't use it, please send me an email with more information so I can support it.
