WebJun 23, 2024 · The intrinsics like WaveActiveBitOr do exactly behave how they are defined, but this is NOT what programmers mostly need. It only syncs the lanes of a wave ( the threads included in the wave ) BUT in most cases we want the “wave intrinsics” to behave like a “ThreadGroup” intrincic to sync the data from ALL threads of a ThreadGroup. WebRDNA runs shader threads in groups of 32 known as wave32. Unused threads in a wave get masked out when running the shader.
