How to Scale Your Model: A Systems View of LLMs on TPUs (jax-ml.github.io)

A new resource titled "A Systems View of LLMs on TPUs" has been released, aimed at optimizing the training and inference of large language models (LLMs) on Tensor Processing Units (TPUs) and Graphics Processing Units (GPUs). This book demystifies the process of scaling LLMs, providing insights on how TPUs operate, the intricacies of model parallelization, and practical strategies to achieve efficient training at scale. It addresses crucial questions surrounding the costs and memory requirements for training LLMs, making it relevant to researchers and engineers who need to navigate the increasing complexity of deep learning models in real-world settings. The significance of this resource lies in its focus on "strong scaling," the ability to enhance throughput proportionally while adding computational resources. With LLMs now pushing hardware limits, understanding the trade-offs between computation and inter-chip communication is vital for effective model training. The book covers practical tutorials, including working with the popular LLaMA 3 model, profiling code in JAX, and strategies for efficient model serving. As the AI landscape evolves, this guide empowers both novice and experienced ML researchers to design and implement robust, scalable architectures, ultimately fostering innovation in the AI/ML community.
