Can I use CUDA under Android OS? How to do it? Thanks
No, CUDA is not supported on Tegra 3, nor any Android devices.
I don’t think this contains any CUDA drivers for Android.
The only CUDA support I know of on ARM platforms is available here:
http://www.nvidia.com/object/carma-devkit.html
That runs a Tegra 3 with a Quadro 1000M, but on Ubuntu rather than Android. I doubt we will see Android drivers for CUDA until NVIDIA starts shipping Tegra chips with CUDA-capable GPUs on-board.
