Researchers have developed OctoPipe, a new system designed to improve the efficiency of training large language models (LLMs) by addressing pipeline bubbles. This system co-optimizes the partitioning, placement, and scheduling of model components. OctoPipe utilizes a graph-based simulator for performance modeling and an iterative tuner to navigate the complex search space, enabling dynamic orchestration of computation and communication. Experiments demonstrate that OctoPipe can achieve up to 1.44x throughput improvement compared to existing state-of-the-art methods across various models and GPU cluster sizes. AI
