OpenCL: clAmdFft on NVIDIA GPUs OpenCL FFT lib from AMD on NVIDIA GPU

Has anyone experiences with running the OpenCL FFT library from AMD (http://developer.amd.com/libraries/appmathlibs/pages/default.aspx) on NVIDIA GPUs?

I’m trying to port an existing algorithm from CUDA (with the most recent CUFFT) to OpenCL. The new code is running fine with an AMD GPU but not with my NVIDIA GPU. The NVIDIA GPU is recognized properly but the resulting array is zero all over without throwing any errors. By the way, the code runs also fine on an Intel Core i3 CPU. So my code seems to be fine.

Any ideas?

We’ve had success with running AMD’s libraries on NVIDIA hardware before. AMD’s libraries are nice in that they will run anywhere.
