I'm new to OpenGL and I have the following problem:
I have some source code and in order to make it faster I want it to be processed on the GPU.
All tutorials on OpenGL I found focus on how to render polygons in three-dimensional space etc. and even though it's very nice to see what OpenGL can do, it's not what I need. I just want to give a function to my graphics card, have it process my data and retrieve the result. Is there a tutorial on how to do this somewhere?
