We provide optimized distributed implementations with minimal extra communications, and seamless integrations with Tensor Parallel, DDP and ZeRO plugins, which automatically uses distributed optimizers with 0 code change. @@ -14,12 +14,6 @@ Apart from the widely adopted Adam and SGD, many modern optimizers require layer ## Optimizers Adafactor is a first-order Adam variant using Non-negative Matrix Factorization(NMF) to reduce memory footprint. CAME improves by introducting a confidence matrix to correct NMF. GaLore further reduces memory by projecting gradients into a low-rank space and 8-bit block-wise quantization. Lamb allows huge batch sizes without lossing accuracy via layer-wise adaptive update bounded by the inverse of its Lipschiz constant. -## API Reference - -{{ autodoc:colossalai.nn.optimizer.distributed_adafactor.DistributedAdaFactor }} -{{ autodoc:colossalai.nn.optimizer.distributed_lamb.DistributedLamb }} -{{ autodoc:colossalai.nn.optimizer.distributed_galore.DistGaloreAwamW }} -{{ autodoc:colossalai.nn.optimizer.distributed_came.DistributedCAME }} ## Hands-On Practice We now demonstrate how to use Distributed Adafactor with booster API combining Tensor Parallel and ZeRO 2 with 4 GPUs. **Note that even if you're not aware of distributed optimizers, the plugins automatically casts yours to the distributed version for convenience.** @@ -140,3 +134,10 @@ optim = DistGaloreAwamW( + +## API Reference + +{{ autodoc:colossalai.nn.optimizer.distributed_adafactor.DistributedAdaFactor }} +{{ autodoc:colossalai.nn.optimizer.distributed_lamb.DistributedLamb }} +{{ autodoc:colossalai.nn.optimizer.distributed_galore.DistGaloreAwamW }} +{{ autodoc:colossalai.nn.optimizer.distributed_came.DistributedCAME }} diff --git a/docs/source/zh-Hans/features/distributed_optimizers.md b/docs/source/zh-Hans/features/distributed_optimizers.md index 36dbdf948..7a7068077 100644 --- a/docs/source/zh-Hans/features/distributed_optimizers.md +++ b/docs/source/zh-Hans/features/distributed_optimizers.md @@ -4,21 +4,15 @@ Author: Wenxuan Tan, Junwen Duan, Renjie Mao **相关论文** - [Adafactor: Adaptive Learning Rates with Sublinear Memory Cost](https://arxiv.org/abs/1804.04235) -- [CAME: Confidence-guided Adaptive Memory Efficient Optimization] (https://arxiv.org/abs/2307.02047) -- [GaLore: Memory-Efficient LLM Training by Gradient Low-Rank Projection] (https://arxiv.org/abs/2403.03507) -- [Large Batch Optimization for Deep Learning: Training BERT in 76 minutes] (https://arxiv.org/pdf/1904.00962) +- [CAME: Confidence-guided Adaptive Memory Efficient Optimization](https://arxiv.org/abs/2307.02047) +- [GaLore: Memory-Efficient LLM Training by Gradient Low-Rank Projection](https://arxiv.org/abs/2403.03507) +- [Large Batch Optimization for Deep Learning: Training BERT in 76 minutes](https://arxiv.org/pdf/1904.00962) ## 介绍 除了广泛采用的Adam和SGD外，许多现代优化器需要逐层统计信息以有效更新参数，因此无法直接应用于模型层在多个设备上分片的并行设置。我们以提供了优化的分布式实现，，并且通过plugin与Tensor Parallel、DDP和ZeRO无缝集成。 ## 优化器 Adafactor 是一种首次采用非负矩阵分解（NMF）的 Adam 变体，用于减少内存占用。CAME 通过引入一个置信度矩阵来改进 NMF 的效果。GaLore 通过将梯度投影到低秩空间，并使用 8 位块状量化进一步减少内存占用。Lamb 允许使用巨大的批量大小而不失准确性，通过按其 Lipschitz 常数的倒数界定的逐层自适应更新实现 -## API 参考 - -{{ autodoc:colossalai.nn.optimizer.distributed_adafactor.DistributedAdaFactor }} -{{ autodoc:colossalai.nn.optimizer.distributed_lamb.DistributedLamb }} -{{ autodoc:colossalai.nn.optimizer.distributed_galore.DistGaloreAwamW }} -{{ autodoc:colossalai.nn.optimizer.distributed_came.DistributedCAME }} ## 使用 现在我们展示如何使用分布式 Adafactor 与 booster API 结合 Tensor Parallel 和 ZeRO 2。即使您不使用distributed optimizer，plugin 也会自动将optimizer转换为分布式版本以方便使用。 @@ -137,3 +131,10 @@ optim = DistGaloreAwamW( + +## API 参考 + +{{ autodoc:colossalai.nn.optimizer.distributed_adafactor.DistributedAdaFactor }} +{{ autodoc:colossalai.nn.optimizer.distributed_lamb.DistributedLamb }} +{{ autodoc:colossalai.nn.optimizer.distributed_galore.DistGaloreAwamW }} +{{ autodoc:colossalai.nn.optimizer.distributed_came.DistributedCAME }}
