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. how to stop my dog from being aggressiveWebb2 maj 2024 · Distributed training is the key to enable training such large ML models. … how to stop my dog from eating dog poopWebbSharded Data Parallel.
