两种Model Parallelism示意图 在DP 设定下,每个显卡都要求保留完整的模型参数,这轻则会造成冗余,重则当模型参数量过大时,全部放下都成问题。Model Parallelism 则是将模型参数进行拆分,每张显卡仅存放部分参数。具体来讲,Model Parallelism 又可以进一步分为Pipeline Parallelism、 Tensor
模型并行（Tensor Model Parallelism）和流水并行（Pipeline Model Parallelism）。
英伟达这套框架主要是通过数据并行(data parallelism)、张量并行(tensor parallelism)、流水线并行(pipeline parallelism)这三点来提高大规模GPU的效率。我们曾在硅星人的文章《Gemini背后,谷歌真正可怕之处并不在模型本身……》中科普到,谷歌提出了一个概念叫做MFU,全称为模型FLOPs利用率(Model FLOPs Utilization),数字越...
From the PR, I have included the changes needed for only InternVL2 model based upon the Architecture InternVLChatModel. On Including these changes I have been able to perform Distributed Inference and Serving for theInternVL2-8Bon Multi-Node Multi-GPU (tensor parallel plus pipeline parallel infer...
PipeEdge: Pipeline Parallelism for Large-Scale Model Inference on Heterogeneous Edge Devices - usc-isi/PipeEdge
A high degree of model parallelism can lead to small GEMMs, potentially decreasing GPU utilization. Figure 2. Model parallelism for model with two transformer layers. Transformer layers are partitioned over pipeline stages (pipeline parallelism); each transformer layer is also split over 2 GPUs using...
Parallelism Model parallelism on multiple cores also improves throughput and latency, which are critical for our heavy workloads. Each Inferentia chip contains four NeuronCores, which can either run separate models simultaneously, or can be pipelined to transfer a single model. In our use case, th...
consuming Huge video memory, computing and other resources. Therefore, the NÜWA team cooperated with colleagues in the system group to set up a variety of parallel mechanisms for NÜWA on the system architecture, such as tensor parallelism, pipeline parallelism and data parallelism. dynamic traini...

虚拟流水并行 (Virtual Pipeline (VP) Parallelism),通过增加虚拟的 stage 来减少 PP 运行时的空泡时间, 动态流水并行 (Dynamic Pipline Parallelism,DPP) 则是增强版本的 VP, 通过合理的设置每个微 batchsize的大小进一步降低空泡时间。 PP 和 VP的基本原理如下: ...
