Created2025-03-27|Reading Paper
Summary Abstract & Introduction & Background and Motivation Deep neural network(DNN)现在越来越大,除了dense model,就是比较传统的model之外,越来越多的人开始关注sparsely activated model。针对dense model,之前有很多auto-parallelization的方法,但是这些方法对sparsely activated model,比如说MoE架构的模型就没那么好用了。所以他们主要做的就是实现对sparsely activated model做自动并行的分布式训练的方法。 Intro就先说一下来龙去脉,就众所周知,scaling law目前对DNN一直没有失效,所以各家基本上就是一直往上堆参数。但模型变大了就练不动了,所以就要找efficient...
Reading Notes for FasterMoE

Summary Abstract & Introduction & Background and Challenges 前面又是简单介绍MoE,基本都一样。 这个也是training方向的,说了三个challenges: dynamic load imbalance 在intro里,叫Dynamic expert selection,就也比较明显,就是每次选的experts不一样。 inefficient synchronous execution mode 在intro里,叫Inefficient synchronous operations,就是expert有dependency,就需要别的worker的data,要等。 congested all-to-all communication 在intro里,叫Mismatch of model design and network topology,感觉他的意思是现在的system只管摆放experts的computation...
