June 2026: Delivered a robust SCC fallback for SubgraphCollector to guarantee acyclic subgraphs for HETERO partitions, addressing complex multi-hop and shared-input cycles introduced by fusion. Implemented iterative Tarjan SCC detection on cross-subgraph DAG and a heuristic cut strategy to isolate cycle edges, preserving merge integrity and avoiding excessive submodel splitting. Validation on YOLO26seg with HETERO:GPU,CPU confirms successful compile and unit test pass. This stabilizes HETERO deployments, reduces runtime assertions, and improves cross-device inference reliability, delivering tangible business value through more predictable performance and deployment confidence. No public API changes.
