            But this is outdated information. Now standard OpenCL. In QT does not have the required functions?

              Nope, Qt does not contain that library.
              But you can use it like in any C++ program.

              And it has QThread to use CPU multithreaded.

                why did you delete your post?
                Just out of curiosity what was wrong with the CUDA reference?

                i see

                      @Mikee No, but you can use OpenCL & QThread, and combine those two. QThread to use all of your cpu, OpenCL to use all of your GPU.

                      Just make sure your cooling is adequate.

                        No need to use QThread when you want to run the same function on the GPU and CPU: you can use OpenCL for both (if it's supported on your system, ofc).

                            @Mikee Has nothing to do with Qt. Qt is only yet another C++ framework (although a quite big one). Just google "opencl tutorial c++".

                                @Mikee I never used OpenCL but did what @Wieland suggested: entered "opencl tutorial c++" in Google and the first match is:
                                http://simpleopencl.blogspot.de/2013/06/tutorial-simple-start-with-opencl-and-c.html

                                On which platform are you?

                                    Qt is just a set of C++ libraries; not a platform, not a programming language.

                                    OpenCV will use CPU and GPU ?

                                    Is that a typo or do you really mean OpenCV?

                                    Anyway: the question is completely off-topic (not related to our framework). please use google search.
