Shardformer: Shardformer负责在张量并行以及流水线并行下切分模型的逻辑，以及前向/后向方法的重载，这个插件为Shardformer功能提供了一个简单易用的接口。与此同时，Shardformer还负责将包括fused normalization, flash attention (xformers), JIT和序列并行在内的各类优化工具融入重载后的前向/后向方法。 + +2. 混合精度训练：插件支持fp16/bf16的混合精度训练。更多关于混合精度训练的参数配置的详细信息请参考 [混合精度训练文档](../features/mixed_precision_training_with_booster.md)。 + +3. Torch DDP: 当流水线并行和Zero不被使用的时候，插件会自动采用Pytorch DDP作为数据并行的策略。更多关于Torch DDP的参数配置的详细信息请参考 [Pytorch DDP 文档](https://pytorch.org/docs/main/generated/torch.nn.parallel.DistributedDataParallel.html#torch.nn.parallel.DistributedDataParallel)。 + +4.
