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.

WebDec 4, 2016 · Under normal circumstances these pipeline bubbles are well covered by the GPU’s zero-overhead context switching, but the effect can become noticeable (to the tune of 2-3% typically) when the control transfer also results in an instruction cache miss, e.g. a loop-closing branch for a loop body that doesn’t fit into the ICache. WebApr 7, 2024 · You can use conditionals to define behavior that the GPU only executes under certain conditions. Different types of conditionals To use conditionals in your shader, you can use the following approaches: Static branching: the shader compiler evaluates conditional code at compile time. Dynamic branching: the GPU evaluates conditional …

Branches Taken Number of branches taken by at least one thread in the warp. Branches Not Taken Number of branches not taken by at least one thread in the warp. Branches Divergent

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.
