因为现在的large scale learning系统在工业界的应用,我觉得还更多是一种以embarrassingly parallel为代表的...
Data Parallel:用于数据量太大,比如OpenImages训练集几百万张图片,单卡训练一个epoch不知道要多久...所以将数据分布在多个GPU上进行并行计算。 Model Parallel(右):用于模型太大,比如一些two-stage models,一张卡都load不了checkpoint。所以将模型拆分放在不同的卡上进行训练。 Data Parallel(左)和Model Parallel(右)...
在随机梯度下降中,数据并行使用了parameter server来做同步,同步的策略就又很多,bsp,ssp以及异步,在Gee...
数据并行和模型并行的区别: https://leimao.github.io/blog/Data-Parallelism-vs-Model-Paralelism/ 原文链接: https://pytorch.org/tutorials/beginner/blitz/data_parallel_tutorial.html#sphx-glr-beginner-blitz-data-parallel-tutorial-py
【期望解释】使用并行模型=1 半自动并行为什么会出现这种情况?按照理解,对于自动并行和半自动并行模型的要求在于 deivce_num=data_parallel model_parallel ...
DataParallel、parallel.data_parallel model_new = nn.DataParallel(model, device_ids) 返回一个新的model output = nn.parallel.data_parallel(model, input, device_ids) 返回输出的数据
