    Kernel result differs between HD 5000 and HD 7000 series GPU

    boxerab

      I have an image processing kernel that performs a discrete wavelet transform on a 2D image.

       

      When I run the kernel on my laptop with mobile HD 5000 series GPU, the result looks correct.

      When I run the same kernel on my desktop with HD 7700 series GPU, there are image artifacts

      at the boundaries of certain wavelet sub bands.

       

      Same kernel, different result.

       

      I would like to get to the bottom of this; can anyone suggest a good way of trouble shooting this kind of issue?

       

      Thanks!
