Abstract: The proliferation of large models based on Transformers has outpaced advances in hardware, resulting in an urgent need for the ability to distribute enormous models across multiple GPUs. Despite this increasing need, the absence of established best practices for selecting an optimal strategy persists, owing to the extensive expertise required in High-Performance Computing (HPC), Deep Learning (DL), and distributed systems. These challenges have motivated both AI and HPC developers to delve into pivotal questions: How can the training and inference efficiency of large models be enhanced to minimize costs? How can larger AI models be accommodated, even with limited resources? What measures can be taken to facilitate broader community access to large models and large-scale applications? In this talk, I will discuss potential solutions to these challenges by exploring hybrid parallelisms, heterogeneous memory management, and the design of user-friendly frameworks such as our open-source systemic solution: Colossal-AI (
