Distributed Machine Learning with Python

By: Guanhua Wang

Overview of this book

Reducing time cost in machine learning leads to a shorter waiting time for model training and a faster model updating cycle. Distributed machine learning enables machine learning practitioners to shorten model training and inference time by orders of magnitude. With the help of this practical guide, you'll be able to put your Python development knowledge to work to get up and running with the implementation of distributed machine learning, including multi-node machine learning systems, in no time. You'll begin by exploring how distributed systems work in the machine learning area and how distributed machine learning is applied to state-of-the-art deep learning models. As you advance, you'll see how to use distributed systems to enhance machine learning model training and serving speed. You'll also get to grips with applying data parallel and model parallel approaches before optimizing the in-parallel model training and serving pipeline in local clusters or cloud environments. By the end of this book, you'll have gained the knowledge and skills needed to build and deploy an efficient data processing pipeline for machine learning model training and inference in a distributed manner.

In this chapter, we discussed how to conduct performance debugging using NVIDIA profiling tools. We also introduced job migration and job multiplexing schemes to further improve hardware utilization. We also covered the topic of heterogeneous model training using different hardware simultaneously.

After reading this chapter, you should understand how to use NVIDIA Nsight for GPU performance debugging. You should also now know how to conduct job multiplexing and job migration during DNN model training or serving. Finally, you should also have acquired basic knowledge of how to conduct single-job training using different hardware concurrently.

Now, we have completed all the chapters for this book. You should understand the key concepts in distributed machine learning, such as data parallel training and serving, model-parallel training and serving, hybrid data and model parallelism, and several advanced techniques for further speed-ups.
