RowwiseParallel :把一个module安装Row维度进行分割,现在仅仅支持nn.Linear and nn.Embedding。当然大部分模型都是由他们组成的。注意!!!分割了模型后,必须自己使用shard等Placement进行维度对齐。如果未指定input_layouts,则将在最后一个维度上分片。如果未指定output_layouts,则复制输出张量。 SequenceParallel:将module...
本文将简单介绍Tensor Parallel的原理和实现,以及适用的场景。 Tensor Parallel最早为Megatron-LM提出的一种大模型并行方式,其核心思想就是将矩阵计算分块到多张GPU上进行计算,优势是:1. 能够降低GPU的峰值显…
输出Embedding层应用：在GPT计算中，Embedding层的权重按列切分，通过all-gather通信得到最终结果。为了降低通信量，可以将GEMM和cross entropy loss进行融合，通信量从【batch-size x sequence-length x vocabulary-size】降低到【batch-size x sequence-length】。总结：Tensor并行训练是一种有效提升大模型训...

Calling Sequences GenerateTensors(Tlist) Parameters Tlist - a list of lists of tensor fields Description Examples Description • With Tlist = [T1,T2,...,Tr] the command GenerateTensors(Tlist) will generate a list of tensors by forming all possible r...
Additionally, Seq2SeqSharp supports parallel execution of neural networks across multiple GPUs. It automatically handles the distribution and synchronization of weights and gradients across devices, manages resources and models, and more—enabling developers to focus entirely on designing and implementing ...
Analytical models are presented to provide enhanced capabilities for modeling fluid flow through natural fractures nested in parallel plate type configurations. The modeled fractures may be arbitrarily positioned, but subgrouped according to the consistent parallel sequences. The derived analytical expressions...
