  • TLDR:Four parallelism plans are left unbounded by the parallelism plans in common use, and each grows differently: expert dispatch with the routing matrix, the vocabulary projection with tokens times vocabulary, gradient checkpoint boundaries with depth times sequence length, and optimizer state with parameter count.

  • 标题中文:长上下文 Mixture-of-Experts 训练中每个内存峰值的平整化
  • TLDR中文:常用的并行方案留下了四种未被约束的并行维度,各自增长方式不同:随路由矩阵增长的专家调度、随 token 数乘词表规模增长的词表投影、随深度乘序列长度增长的梯度检查点边界,以及随参数量增长的优化器状态。
