SprayCast: Congestion-Adaptive Native Multicast for Dynamic Sparse All-to-All Communication

Yingying Zeng, Ning Xu, Xiaobin Tan, Xuan Zhao et autres

Mixture-of-Experts (MoE) models outperform traditional dense models through sparse expert activation, where each token is dynamically routed to a small subset of experts. Across many tokens, these sparse Dispatch operations induce all-to-all traffic, making communication a major bottleneck for both training and …
