Compute Shaders and Memory Barriers

Question asked by albinengström on Aug 18, 2014

Greetings, I've been trying to learn about learn about the compute shader functionality that come with the relatively new OpenGL 4.3, however i have run into some problems that i cannot solve myself, there are too many unknown factors for me to give you a well informed question or code, so i'd like to rudely start by simply asking if there are any known issues with the memory barrier functionality or reading/writing the same buffers in several compute shaders, i have noticed that there are others with similar problems, but these do not appear to have been resolved. The setup works for Nvidia cards, which makes it very hard for me to tell if i'm doing something wrong or not.




Thanks in advance for any answers .
