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 ... 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 … See more The simplest approach to implementing branching on the GPU is predication, as discussed earlier. With predication, the GPU effectively … See more Because explicit branching can be tricky on GPUs, it's handy to have a number of techniques in your repertoire. A useful strategy is to move flow-control decisions up the pipeline to an earlier stage, where they can be more … See more In the preceding example, the result of a branch was constant over a large domain of input (or range of output) values. Similarly, sometimes the result of a branch is constant for a … See more When performing computations on streams or arrays of data on the CPU, most programmers know that they should strive to avoid branching inside the inner loops of the computation. Doing so can cause the pipeline to … See more

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.
