WebBranch divergence is a major cause for performance degradation in GPGPUs. As we discussed earlier, the immediate postdominator (PDOM) lacks the capability to reconverge threads at the beginning for branch divergence to further improve the performance. DWF is proposed in Ref. [24] to efficiently handle the threads’ divergence. WebIn the GPU’s SIMT (Single Instruction Multiple Thread) architecture, the GPU streaming multiprocessors (SM) execute thread instructions in groups of 32 called warps. The threads in a SIMT warp are all of the same type and begin at the same program address, but they are free to branch and execute independently.

"WebJun 17, 2024 · GPUs operate best when the logic/throughput is uniform. So reducing the branching/decision making to the simplest possible pass can be very beneficial. But again this can very much be a case by case basis, because you're adding an extra pass over data. First the full screen and then the collection pass. " - Gpu branching

Web31.3.1 Streams: GPU Textures = CPU Arrays This one is easy. The fundamental array data structures on GPUs are textures and vertex arrays. As we observed before, fragment processors tend to be more useful for GPGPU than vertex processors. Therefore, anywhere we would use an array of data on the CPU, we can use a texture on the GPU.
