Groupshared memory and parallel reduction over multiple kernel dispatch
I am doing some parallel reduction and mostly following these nVidia slides. However they are not very detailed in places or I might be missing/misunderstanding something.
Edit 2:
While I figured ...

GL_OUT_OF_MEMORY Error when glDispatchCompute takes longer
I built a simple Ray Tracer which takes use of OpenGL's Compute Shader and traces ".obj" Files.
The results are passed to the Host-Program via glMapBufferRange after finishing computing.

Is a smaller local-size/threadgroup-size better for compute shader performance?
A compute shader defines the number of threads it requires to be executed.
This number can be called "local size" or "threadgroup size" according to the API, and be factored into 3 separate dimensions ...

Do GL compute shaders trigger TDR if they crash. Not just timeout?
I'm getting a TDR trigger after 4ms with a GL4.3 compute shader. tdrDelay is currently set to 30 secs, this obviously isn't long enough to get a timeout with the default Windows 11 tdrDelay value let ...

Opengl binding different mipmap levels of same texture2darray for use in compute shader. How to handle variable nr of levels?
So I want to make a compute shader that uses a coarse-to-fine approach.
As I have learned about open gl mipmap levels it seems they could be very useful.
However the only binding method which I have ...

Does RWStructuredBuffer have built-in overflow protection in hlsl?
It appears that reads to indices outside the range of a ComputeBuffer always return 0, and writes to out-of-range indices do not cause any exceptions or runtime errors. Is there built-in range-...

Offsetting value in shader causes unexpected/wrong logic
Let me explain what I am doing. I am trying to reduce the memory footprint of a voxel based algorithm by storing the voxel data as a hash map in an SSBO, as opposed to a 3D image.
I am visualizing the ...
