Pytorch中all_to_all_single算子的定义如下: https://pytorch.org/docs/stable/distributed.html 其中可以设置input_splits来进行细粒度的划分到每张卡的数据。 而MS中似乎只可以指定划分的数目,不能控制每张卡划分一部分,这给一些功能的实现带来不便。 可以说明一下,MS中all2

文章简介这篇文章只详细介绍all_gather和all_reduce;gather、reduce、scatter方法原理大体相同,具体功能,可以参考下图 all_gather函数定义其中tensor_list,是list,大小是word_size,每个元素为了是gather后,…

Hierarchical Interface TorchDrug is designed to cater all kinds of development. It has a hierarchical interface, which ranges from low-level data structures and operations, mid-level layers and models, to high-level tasks. We can easily customize modules at any level with minimal efforts by utili...
在使用混合精度AMP训练时,确保在调用scaler.unscale_之前调用xm.all_reduce,以确保基于all_reduce之后的梯度进行溢出检测。 使用xlarun拉起任务。 xlarun --nproc_per_node=8 YOUR_MODEL.py 说明 多机情况使用方法与torchrun相同。 接入混合精度 通过混合精度训练可以加速模型训练速度,在单卡训练或分布式训练的基础...

The ultimate aim is to be similar to the current hardware vendors adding LLVM target support, rather than each one implementing Clang or a C++ frontend. All the roads from PyTorch to Torch MLIR Dialect We have few paths to lower down to the Torch MLIR Dialect. ONNX as the entry points....
