AWhat changed
Combined single-controller orchestration with distributed model-worker execution and hierarchical dataflow APIs, plus actor resharding between training and generation through a hybrid engine.
Scientific scope
Combined single-controller orchestration with distributed model-worker execution and hierarchical dataflow APIs, plus actor resharding between training and generation through a hybrid engine. Framework/system contribution, not a new RL objective. Throughput and memory figures depend on model/device layout and baselines. Original preprint is2024 and the displayed proceedings version is EuroSys2025; later verl features are not all backdated.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
