Faster Synchronous On-Policy RL via Straggler-Aware Group Sizing

Researchers propose Straggler-Aware Group Control (SAGC), a dynamic optimization technique that improves the efficiency of synchronous reinforcement learning by adapting group sizes based on observed training behavior. The method addresses a critical bottleneck in on-policy RL where slow individual rollouts delay entire group computations, achieving better wall-clock performance while maintaining or improving model quality on reasoning benchmarks.
