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.

Summary

In this chapter, we discussed advanced techniques on a hybrid of data parallelism and model parallelism. Next, we did a case study of Megatron-LM and its implementation, followed by a case study of Mesh-TensorFlow and its implementation. We ended the chapter by learning about the pros and cons of the two systems.

After reading this chapter, you should understand how Megatron-LM achieves both model parallelism and data parallelism simultaneously. You should be able to use Megatron-LM to launch your own DNN model training job. In addition, you should be familiar with the high-level idea of Mesh-TensorFlow and how to use it for model training as well.

In the next chapter, we will discuss federated learning.
