New method speeds up RLHF training with adaptive parallelism

Researchers have developed a new method called PAT to accelerate the training of Reinforcement Learning from Human Feedback (RLHF) models. This technique dynamically adjusts tensor parallelism during the generation stage, addressing the issue of long response times bottlenecking the process. By intelligently reconfiguring parallelism and managing decoding states, PAT has demonstrated significant reductions in both generation and end-to-end training latency for models like LLaMA3.1-8B and Qwen3-14B.
