Hi everyone,

I have successfully sent the data into GPU's memory using VBO.
So now, I want to do password matching job on these data. I had searched through all the openGL functions. Seems like none of the functions I can use to do this job. What can I do now? Write my own function? How? Anyone has this kind of knowledge please drop a message here ^.^

OpenGL is a graphics library; it's right there in the name.

If you want to use the GPU to do non-graphics work, you should investigate an API that specifically does this. Like OpenCL. Or if you want to restrict yourself to NVIDIA, CUDA.

Time to say "impossible", I think. There is no OpenGL function that does password matching. Why do you want to do password matching on the GPU anyway? Seems a mite crazy.

Maybe he meant password cracking? Maybe because on GPU it could be faster.. .LOL

Don't you need GL_EXT_password_cracking for that?

Apps exist that do password cracking on the GPU.
