RLHF Performance Optimization: PPO Algorithm Acceleration Techniques
The article presents three RLHF‑PPO acceleration techniques—TRT‑LLM‑based text generation speedups, selective activation recomputation with sequence parallelism for dynamic memory reduction, and overlapping pipeline stages for system‑level parallelism—demonstrating a 350 % throughput boost on a 10 B model using 16 A100 GPUs.
