Gpipe通过实验证明,当 M>=4K 时,bubble产生的空转时间占比对最终训练时长影响是微小的,可以忽略不计。将batch切好,并逐一送入GPU的过程,就像一个流水生产线一样(类似于CPU里的流水线),因此也被称为Pipeline Parallelism。 3.2 re-materialization(active checkpoint) 解决了GPU的空置问题,提升了GPU计算的整体效率。
2.2、Pipeline Parallelism - Part 1 - Split into micro-batches 2.3、Pipeline Parallelism - Part 2 - 通过 re-materialization 降低显存占用 2.4、空间复杂度 && GPU 空闲时间 3、实验结果 3.1、增加 GPU 数量,训练更大模型 3.2、训练速度如何 4、总结 【本文是 “LLM 分布式训练系列” 的第 2 篇,持续更新...
Pipeline parallelism is when different stages of a process are executed in separate devices simultaneously. For instance, in the context of Machine Learning, various layers of a model can be distributed across different devices to create a pipeline. ...
Pipeline parallelismEdge computingCollaborative machine learning (CML) techniques, such as federated learning, have been proposed to train deep learning models across multiple mobile devices and a server. CML techniques are privacy-preserving as a local model that is trained on each device instead of ...
Single streams can be processed asynchronously, but this is also not scalable. Dependencies between frames prevent parallelism. Turning off these dependencies reduces quality at a given bitrate. Increasing the number of frames in flight also increases latency. ...
PiPPy: Pipeline Parallelism for PyTorch Note PiPPy has been migrated intoPyTorchas a subpackage:torch.distributed.pipelining. You can find the detailed documentationhere. The current repo mainly serves as a land ofexamples. The PiPPy library code will be removed. Please use the APIs intorch.distri...
Hey vllm team, Hope you're all doing great! I‘m focusing on pipeline parallel inference and I hope it can be support on vllm. I noticed that pipeline parallelism was on the old roadmap(#244) , but it's not on the new roadmap(#2681). Just...

PipeDream, a system developed as part of Microsoft Research’sProject Fiddle(opens in new tab), introduces pipeline parallelism, a new way to parallelize DNN training by combining traditional intra-batch parallelism (model and data parallelism) with inter-batch parallelism (pi...
