I am a newbie to the ATI Stream, and when I tested the provided projects, I find something wrong with the project: tutorials\ScatterStreamKernel.

in the main() function.

    // Specifying the width and height of the 2D buffer
    const unsigned int width = 4096;
    const unsigned int height = 4096;

But if I changed the width and height to 8192(or even more than 4096), and I found that the results of GPU are different from the results of CPU, and also the results of GPU are wrong. If the width and height are lower than 4096, it works ok.

Therefore, is it the problem of the ATI GPU? I am using the Fire Stream 9270.

Thanks.
