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. At each instruction issue time ... WebGPU uses SIMD pipeline to save area on control logic. " Group scalar threads into warps Branch divergence occurs when threads inside warps branch to different execution …

WebSep 18, 2015 · There are three current methods used by GPUs to implement branching: MIMD branching, SIMD branching, and condition codes. MIMD branching is the ideal case, in which different processors can take different data-dependent branches without penalty, much like a CPU. The NVIDIA GeForce 6 Series supports MIMD branching in … WebMay 3, 2009 · Branching is done via predication, so you’re still effectively executing an entire warp when you have a divergent branch, you’re just masking out some number of threads from having any effect (e.g., don’t write to registers, don’t load, don’t store, don’t set any error conditions).

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.
