Supercomputing for Artificial Intelligence: Foundations, Architectures, and Scaling Deep Learning Workloads

The definitive practical guide to running Artificial Intelligence at scale.Learn how to train deep learning models and LLMs on GPUs, clusters, and supercomputers with real tools like PyTorch, CUDA, and SLURM.Are you ready to go beyond the basics of AI and truly harness the power of large-scale computing? Supercomputing for Artificial Intelligence is your practical guide to mastering the infrastructures, tools, and techniques needed to scale deep learning systems—from neural networks to large language models (LLMs).Designed for graduate students, AI researchers, data scientists, and engineers, this book bridges the gap between high-performance computing (HPC) and real-world AI applications. Whether you're working in academia, industry, or exploring advanced AI on your own, you'll find clear explanations and hands-on examples built around tools like PyTorch, CUDA, MPI, SLURM, and multi-GPU distributed training.With over 650 pages of rigorously tested content, this book takes you on an end-to-end journey through:The foundations of supercomputing and its role in AI workloadsPractical GPU programming with CUDA and distributed systemsParallel programming with MPI on modern clustersEfficient training of neural networks, CNNs, and TransformersPerformance optimization for deep learning at scaleDistributed training with PyTorch DistributedDataParallel (DDP)Building and scaling LLMs using real biomedical and NLP datasetsJupyter, Google Colab, and Hugging Face workflowsDeployment and inference strategies for modern LLMsAll source code, configuration files, and job scripts are available in a public GitHub repository. The material is field-tested through years of teaching and research at the Barcelona Supercomputing Center, and can be applied on local GPU setups, cloud platforms, and HPC clusters.This book is ideal for:Instructors looking for practical material for AI and HPC coursesStudents and professionals wanting to learn how to run AI at scaleEngineers transitioning from standard AI workflows to distributed environmentsResearchers working on LLMs and interested in reproducible pipelinesDo I need a supercomputer to use this book? Not at all. While some examples are run on large systems like MareNostrum, some code is designed to scale—from a single GPU to a full HPC node. You’ll find guidance for running experiments in Google Colab and containerized environments.Whether you're teaching AI, training models at scale, or simply curious about the invisible infrastructure powering today’s most powerful AI systems, this book is your companion to understanding and leveraging supercomputing for artificial intelligence.Start scaling your deep learning models today—this is not just a book, it’s your gateway to HPC for AI.
