Megatron-LM: model parallelism for large-model training

A 2019 paper describes splitting the weights of language models with billions of parameters across GPUs, addressing models whose weights do not fit on a single GPU.

The 2019 paper on Megatron-LM describes model parallelism for training language models with billions of parameters. The technique divides model weights across GPUs, addressing cases where the weights do not fit on a single GPU.
