WebGPU Execution. GPUs rely on large data-parallel workloads to achieve performance. As a result, single-task kernels are rarely utilized, and NDRange kernels are needed to fully … 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

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. 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.
