Overview of this book

Machine learning (ML) and high-performance computing (HPC) on AWS run compute-intensive workloads across industries and emerging applications. Its use cases can be linked to various verticals, such as computational fluid dynamics (CFD), genomics, and autonomous vehicles. This book provides end-to-end guidance, starting with HPC concepts for storage and networking. It then progresses to working examples on how to process large datasets using SageMaker Studio and EMR. Next, you’ll learn how to build, train, and deploy large models using distributed training. Later chapters also guide you through deploying models to edge devices using SageMaker and IoT Greengrass, and performance optimization of ML models, for low latency use cases. By the end of this book, you’ll be able to build, train, and deploy your own large-scale ML application, using HPC on AWS, following industry best practices and addressing the key pain points encountered in the application life cycle.

Discussing how ML can be applied to CFD

CFD, being a field that has been around for decades, has matured to be very useful to companies in various domains and has also been implemented at scale using cloud providers. Recent advances in ML have been applied to CFD, and in this section, we will provide readers with pointers to articles written about this domain.

Overall, we see deep learning techniques being applied in two primary ways:

  • Using deep learning to map inputs to outputs. We explored the flow over an airfoil in this chapter and visualized these results. If we had enough input variation and saved the outputs as images, we could use autoencoders or Generative Adversarial Networks (GANs) to generate these images. As an example, the following paper uses GANs to predict flows over airfoils using sparse data: https://www.sciencedirect.com/science/article/pii/S1000936121000728. As we can see in Figure 11.22, the flow fields predicted by CFD and the GAN are visually very...
