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. how michael burry made money in 2008WebGPU parallelism comes with another characteristic related to the handling of branching. Branching means that, as part of execution, a decision is made to run a certain set of instructions based on a test operation per processed element.
