imageAtomicAdd on R16I textures
In my application I use single-channel signed integer texture of the format R16I to store data. Attempting to use imageAtomicAdd() on the image the texture is bound to fails, with debug output as:...

Oh wow, I didn't even think of reading the GLSL spec. Thank you very much for the clarification.

About the First, Have you tried without std430? Or to try std140.If possible, please supply your GLSL shader source.

As I said, I have workarounds. I am able to use the std430 layout in shaders while clearing the buffer with same default for the three (RGB) channels. The function glClearBufferData works without any...

Hi, The ID is driver assigned and is implementation dependent. It's much like compiler warning numbers. You can chose to ignore specific items by ID, sort errors by their IDs and so on, but there is no...
View ArticleRe: Violation access with cl_event from GLsync usage
Does your application create multiple OpenGL contexts? Are you using a toolkit to set up OpenGL or is it your own code? Thanks, Graham
View ArticleRe: Violation access with cl_event from GLsync usage
I'm using glfw3 to create the Windows context. Since I create a GL 4.3 context I think it creates a fake context to get a pointer to wglCreateContextAttribsARB.I use GLEW too.

The issue of "atomicCompSwap" has been found in the driver. The second and third parameters are disordered. It may be fixed released in some days. I have wrote these code to test glClearBufferData. It...

Do you have any news regarding this? I wonder if it's better for me to wait one or two weeks or downgrade to 14.9. Thanks!
