WebSep 18, 2015 · Branching can be a major bottleneck on a GPU due to branch divergence. Since threads in a warp are executed in SIMT (single instruction multiple threads), if one thread takes a branch, all must execute the same branch. WebGPU Execution.

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). WebBranch EfficiencyStates the ratio of uniform control flow decisions over all executed branch instructions. Shown per-SM (the bars) and averaged over all SMs (the Branch line).
