TensorHub: Scalable and Elastic Weight Transfer for LLM RL Training
TensorHub introduces Reference-Oriented Storage (ROS), a novel weight transfer system that enables efficient reinforcement learning training across distributed GPU clusters without physically copying model weights. The production-deployed system achieves significant performance improvements, reducing GPU stall time by up to 6.7x for rollout operations and improving cross-datacenter transfers by 19x.
