OmniPipe is proposed, a flexible bidirectional multi-pipeline parallelism scheme for unified dense and MoE LLM training that minimizes the pipeline bubble ratio while effectively overlapping EP communication with computation, enabled by the flexible and scalable parallelism scheme of bidirectional pipelines.

Mixture-of-Experts (MoE) has become the de facto architecture for scaling large language models, offering expanded capacity with manageable compute. Pipeline parallelism (PP) is indispensable for distributed MoE training, but state-of-the-art PP schemes face three major limitations: large pipeline bubbles, high per-sta...

Dynamo-MoE, an out-of-box MoE inference framework to bridge the performance gap by dynamic parallelization strategies, integrates a novel load balancing approach based on token sorting and on-demand expert loading to solve the workload imbalance issue in the scenario of high workload.
