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。 ...
模型并行分为两种：流水线并行和张量并行，也可以称作算子内并行（intra-operator parallelism）和算子间并...
pipeline model parallelism (PMP)Deep learning has become the cornerstone of artificial intelligence, playing an increasingly important role in human production and lifestyle. However, as the complexity of problem-solving increases, deep learning models become increasingly intricate, resulting in a ...
model parallelism / quantization, both techniques are more advanced and experimental, since Evo is not a native huggingface class, most of their utilities for MP / quantization do not work since particular methods are not implemented Besides extensive research and trial and errors, I couldnt get to...

A hybrid approach that combines data parallelism, model parallelism and pipeline processing, is also possible to overcome the drawbacks of each scheme[34]. In all of the above, concurrent execution is the key to increased performance. Placing different layers of the model in different devices, but...
而对和micro-batch based pipeline parallelism的结合可能比较迷,但其实他们也是正交的。切分micro-batch不影响切分sequence length,下面这张图其实已经展现这种结合形式了,不同颜色的方块表示不同micro-batch。 TeraPipe的切分,上面展示过了 至于在这种混合切分下,Batch是否还应该切分成均匀的大小,也是不一定的。这需要...

图2:Parallel vs V-Shape 这种设计的灵感来源于式(1),该方程说明峰值内存大小取决于 lifespan 之和。 观察图2 可以发现,以 parallel (interleaved-1F1B) 的方式在设备上放置多个 stage 时,明显存在峰值内存不平衡的情况,其内存瓶颈与 (l_1+l_4) 成比例。 The V-Shape schedule requests the model to be...
