UnverifiedThe core engineering challenges of the MoE architecture include load balancing (requiring the introduction of auxiliary loss functions to mitigate expert collapse) and cross-device communication overhead in distributed training and inference.79% similarUnverifiedExpert parallel training for MoE models requires additional All-to-All communication primitives, places high demands on network interconnect bandwidth, and typically requires NVLink or InfiniBand-level interconnects.72% similarUnverifiedThe core trade-off of MoE is that training requires more GPU memory (all expert weights must be loaded), but FLOPs consumption during inference can be significantly reduced.65% similarUnverified大模型训练高度依赖集群内部的高速互联（如NVLink或InfiniBand），跨云迁移意味着需要重新优化分布式训练的通信拓扑64% similar
