WebFeb 23, 2013 · This work proposes a change to the stack hardware in which the execution of two different paths can be interleaved and shows how dual-path execution can be implemented with only modest changes to current hardware and that parallelism is increased without sacrificing optimal (structured) control-flow reconvergence. Current … WebJul 12, 2024 · GPGPUs use the Single-Instruction-Multiple-Thread (SIMT) execution model where a group of threads-wavefront or warp-execute instructions in lockstep. When threads in a group encounter a branching instruction, not all threads in the group take the same path, a phenomenon known as control-flow divergence. The control-flow divergence …
