随着大模型的迅猛发展，混合专家（ MoE）模型凭借其独特的架构优势，成为扩展模型能力的重要 方向。MoE通过创新性的路由机制，动态地将输入token分配给不同的专家网络，不仅高效实现了模 型参数的规模化扩展，更在处理复杂任务时展现出显著优势。然而， 将 MoE模型在分布式集群环境 下进行训练时，训练效率不足，已成为亟待解决的难题。 实践 表明， MoE模型训练集群的效率面临两方面挑战：（1） 专家并行引入计算和通信等待 ， 当 模型规模较大时，需要切分专家到不同设备形成并行（ EP），这就引入额外 All-to-All 通信，同时 MoE层绝大部分EP通信与计算存在时序依赖关系， 一般的 串行执行模式 会 导致大量计算单元空闲 ， 等待 通信；（ 2） 负 载不均引入计算和计算等待 ， MoE算法核心是"有能者居之"，在训练过 程中会出现 部分热专家被频繁调用，而冷专家使用率较低 ；同时，真实训练数据的长度不一，不同 的模型层（如稀疏层、嵌入层等）的计算量也存在明显差异，造成不同卡之间计算也在互相等待。 形象地说， MoE训练系统就像一个交通拥塞严重的城区：1）人车混行阻塞，所有车辆（计算）必须 等待行人（通 ...
