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。
算法的迭代创新 几种经典的分布式并行范式,包括流水线并行(Pipeline Parallelism),数据并行(Data Parallelism)和张量并行(Tensor Parallesim)。 微软开源的分布式训练框DeepSpeed,融合了这三种并行范式,开发出3D并行的框架,实现了千亿级别模型参数的训练。 经典的流水线并行范式有Google推出的Gpipe, 微软推出的PipeDream。 ...

- 低端低带宽芯片部署策略不首选pipeline parallelism - 通过pipeline parallelism优化Throughput没有缺点 - 可以每个芯片只放一个layer,搞成PP_Size = 48,48片芯片流水并行 - 每个芯片上的BatchSize可以开到很大,在用户Query数量很大的时候可以掩盖访存开销和通信开销 - 采用pipeline parallelism会放大Latency - 每个query...
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...
In pipelineparallelism, different stages of the process are carried out in different devices, but concurrently. For example, different layers of the ML model can be placed in different devices, forming a pipeline[30,33]. View article A Survey and Taxonomy of FPGA-based Deep Learning Accelerators...
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...
