WAR: Workload-Aware Rollouts for Synchronous Agentic Reinforcement Learning
Ryan Xu, Atlas Zhao, David Bao, Frank Du
Long-horizon rollout generation has become the dominant systems bottleneck in agentic reinforcement learning (RL). As agents interact with environments over many turns, trajectories rapidly grow to tens of thousands of tokens, making synchronous RL training increasingly constrain…
