Can I use GPU?

OpenCL

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.

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

QThread can use GPU?

@Mikee no

@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).

@Wieland How can I add a function from OpenCL in QT?

[A Former User]

@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]

Maybe you know where I can download OpenCL ?

[jsulm]

@Mikee I never used OpenCL but did what @Wieland suggested: entered "opencl tutorial c++" in Google and the first match is:

On which platform are you?

[Mikee]

On Qt.
OpenCV will use CPU and GPU?

On Qt.

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.
