Could you kindly share a source for this? Shader Execution Reordering (SER) is available for Ray tracing, but it is not a general-purpose feature that can be used in generic compute shaders.

I would strongly advise against this. GPUs are highly efficient when neighboring threads within a warp access neighboring data and follow largely the same code path. Even across warps, data locality is highly desirable.
