    Re: float multiplication on GPU returns NaN

    It was in fact a driver issue.
    After updating the driver for the AMD HD5770 to Catalyst 11.2 the multiplication
    works fine on GPU.

    float multiplication on GPU returns NaN

    Hi,
    I have some float variables that won't allow multiplication on the GPU.
    The multiplication of the float variable "val" with any component(x,y or z) of the
    Vec3 "dp" will always result in a...

    Re: Iterate over built-in vector type?

    Thanks. I am aware of how the built-in vector types work and
    that they are not comparable to arrays. But I have to pass
    lots of uint-arrays with a length of 16 into a kernel and thought that...

    Iterate over built-in vector type?

    Hi.
    Is there a possibility to iterate over the built-in vector types
    (float4, uint16, etc.) ?
    As far as I've seen in the "quick reference card" it is only possible
    to access the elements using...
  5. Re: C++ templated cl::Buffer creation problem on AMD platfor

    Sorry. My fault. Pretty trivial error:
    It was just a missing argument in the line:

    cl::Buffer b = cl::Buffer(OpenCLClass::GetInstance().GetContext(), flag_, numBytes_, &bufferError);
    Changing it...
  6. C++ templated cl::Buffer creation problem on AMD platform

    Hi.
    I made a template function to simplify the creation of cl::Buffers
    by passing the data type as a template argument:


    template<typename T>
    cl::Buffer MyOpenCLWrapper::CreateBuffer(const...

    Release cl::Context

    Hi everybody,
    I started off learning OpenCL using the normal C headers and now
    switched over to C++.
    When using C I had to release my cl_context by calling clReleaseContext(myContext),
    but how...
