What is the role of compute graph partitioning in torch.compile?
Updated May 17, 2026
Short answer
Graph partitioning splits computation into optimized subgraphs for backend compilation.
Deep explanation
TorchDynamo captures graphs and partitions them into regions that can be optimized by backends like TorchInductor. Unsupported ops remain in eager mode, while supported regions are compiled.
