Hands-On High Performance with Go

By: Bob Strecansky

Overview of this book

Go is an easy-to-write language that is popular among developers thanks to its features such as concurrency, portability, and ability to reduce complexity. This Golang book will teach you how to construct idiomatic Go code that is reusable and highly performant. Starting with an introduction to performance concepts, you’ll understand the ideology behind Go’s performance. You’ll then learn how to effectively implement Go data structures and algorithms along with exploring data manipulation and organization to write programs for scalable software. This book covers channels and goroutines for parallelism and concurrency to write high-performance code for distributed systems. As you advance, you’ll learn how to manage memory effectively. You’ll explore the compute unified device architecture (CUDA) application programming interface (API), use containers to build Go code, and work with the Go build cache for quicker compilation. You’ll also get to grips with profiling and tracing Go code for detecting bottlenecks in your system. Finally, you’ll evaluate clusters and job queues for performance optimization and monitor the application for performance regression. By the end of this Go programming book, you’ll be able to improve existing code and fulfill customer requirements by writing efficient programs.

Understanding algorithms in the STL

Algorithms in the STL perform functions such as sorting and searching, as well as manipulating and counting data. These are called by the <algorithm> header in C++ and are used on ranges of elements. The groups of objects that are modified do not impact the structure of the container they are associated with. The patterns outlined in each of the subheadings here use Go's language structure to implement these algorithms. The following types of algorithm will be explained in this section of the chapter:

  • Sort
  • Reverse
  • Min and max elements
  • Binary search

Being able to understand how all of these algorithms work will help you to produce performant code when you need to use these techniques to manipulate data structures using algorithms.
