TopoEP: Topology-Aware Load Balancing for Expert-Parallel MoE Training

Jiacheng Zhu, Xie Zhao, Gongming Zhao et al. · 2026

Dynamic routing creates severe load imbalance in large-scale expert-parallel Mixture-of-Experts (MoE) training, turning GPUs that host hot experts into stragglers. As each MoE layer waits for its slowest rank, these stragglers prolong the expert-parallel stage and reduce overall training efficiency. Existing expert-par …
