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. WebIn the GPU’s SIMT (Single Instruction Multiple Thread) architecture, the GPU streaming multiprocessors (SM) execute thread instructions in groups of 32 called warps.
