Sharded ddp training
Webb我们都知道pytorch DDP用起来简单方便,但是要求整个模型能加载一个GPU上,这使得大模型的训练需要使用额外复杂的设置进行模型拆分。 pytorch的FSDP从DeepSpeed ZeRO以及FairScale的FSDP中获取灵感,打破模型分片的障碍( 包括模型参数,梯度,优化器状态 ),同时仍然保持了数据并行的简单性。 Webb10 dec. 2024 · Lightning 1.1 reveals Sharded Training — train deep learning models on multiple GPUs saving over 50% on memory, with no performance loss or code change required!

WebbOn 8 x 32GB GPUs, sharding enables training the same 13B parameter model without offloading the parameters to CPU. However, without CPU offloading we'd only be able to fit a batch size of 1 per GPU, which would cause training speed to suffer. We obtain the best performance on 8 GPUs by combining full sharding and CPU offloading. Webb21 mars 2024 · Under the hood, Sharded Training is similar to Data Parallel Training, with …
