Faster Synchronous On-Policy RL via Straggler-Aware Group Sizing
The paper introduces Straggler-Aware Group Control (SAGC), a dynamic group-size controller that optimizes synchronous on-policy RL training by adapting group size to minimize delays caused by slow rollouts (stragglers), thereby improving wall-clock efficiency and model performance.
