Penned by an expert in High-Performance Computing (HPC) with over 25 years of experience, this book is your guide to enhancing the performance of model training using PyTorch, one of the most widely adopted machine learning frameworks.

You'll start by understanding how model complexity impacts training time before discovering distinct levels of performance tuning to expedite the training process. You'll also learn how to use a new PyTorch feature to compile the model and train it faster, alongside learning how to benefit from specialized libraries to optimize the training process on the CPU. As you progress, you'll gain insights into building an efficient data pipeline to keep accelerators occupied during the entire training execution and explore strategies for reducing model complexity and adopting mixed precision to minimize computing time and memory consumption. The book will get you acquainted with distributed training and show you how to use PyTorch to harness the computing power of multicore systems and multi-GPU environments available on single or multiple machines.

By the end of this book, you'll be equipped with a suite of techniques, approaches, and strategies to speed up training, so you can focus on what really matters-building stunning models!

• Compile the model to train it faster
• Use specialized libraries to optimize the training on the CPU
• Build a data pipeline to boost GPU execution
• Simplify the model through pruning and compression techniques
• Adopt automatic mixed precision without penalizing the model's accuracy
