Large AI models are transforming the digital world. Generative language models like Turing-NLG, ChatGPT, and GPT-4, powered by large language models (LLMs), are incredibly versatile, capable of performing tasks like summarization, coding, and translation. Similarly, large multimodal generative models like DALL·E, Microsoft Designer, and Bing Image Creator can generate art, architecture, videos, and other digital assets, empowering content creators, architects, and engineers to explore new frontiers of creative productivity. However, training these large models requires considerable memory and computing resources across hundreds or even thousands of GPU devices. For instance, training the Megatron-Turing NLG 530B model utilized over 4,000 NVidia A100 GPUs. Efficiently leveraging these resources requires a complex system of optimizations to partition the models into pieces that fit into the memory of individual devices, and to efficiently parallelize the computing across these devices.
