Solution Overview
GPT NeoX and Pythia models
Large language models (LLMs) such as GPT NeoX and Pythia have gained rapid adoption due to their exceptional performance in tasks like speech recognition, text generation, and question answering. These models, with billions of parameters, are trained on AWS Trainium, a purpose-built machine learning accelerator optimized for deep learning training, using the Neuron NeMo library.
Walkthrough
The pre-training and fine-tuning of these models on AWS Trainium involves downloading pre-tokenized datasets, implementing partial rotation for efficient processing, and executing the training using SLURM managed multi-node Amazon EC2 Trn1 clusters.
Training Steps
The training process involves compiling the model, executing the training, and monitoring the results using tensorboard. The throughput and cost-throughput ratio for different model configurations are compared, demonstrating the cost-effectiveness of training on AWS Trainium.
Pre-training and Fine-tuning Experiments
The experiments show the pre-training and fine-tuning of GPT NeoX and Pythia models on AWS Trainium, along with the comparison of training results with GPU clusters. The cost-normalized throughput and model accuracy are highlighted, showcasing the efficiency and effectiveness of training on AWS Trainium.
