    float4 a;
    // ...
    float4 b = pow( a, 2.0f );

    The documentation says that the arguments have to be the same type, so I...
  3. Re: Reaction-diffusion: an ideal system for OpenCL?

    It's good to hear that this is a suitable GPU problem, I had been coming to the conclusion that there wasn't enough processing per work item.



    In GrayScott_2x2 I'm using float4 to retrieve a...
