    Few thoughts on OpenCL, first custom problem solved

    After few weeks swimming in OpenCL, I found out few interesting facts.

    You can download ATi Computing SDK and use OpenCL.DLL from there to run OpenCL on your multicore AMD CPU, but on my 1 cored Sempron it performs a bit worse than C#.

    Situation with GPU OpenCL is much more interesting, the drivers converged both on ATi and NVIDIA side to state you can use OpenCL without being angry too often.

    I just finished fine tuning the first custom problem for GPU, which is not adaptation of classic problems such a convolution or FFT. More or less it is precomputing 360° ray collision with model of real world environment.
    The original version takes minutes on CPU, on 9500GT GPU I get 40x boost, resulting in change to just few seconds. This all driven from within ThinBasic.

    I am prepairing article on this topic, which sadly cannot be published before September 2010, when it will be presented on robotics conference. To entertain you a bit, I attach the image output of the method in ground floor of university building.
