The Art of Writing Efficient Programs

Overview of this book

The great free lunch of "performance taking care of itself" is over. Until recently, programs got faster by themselves as CPUs were upgraded, but that doesn't happen anymore. The clock frequency of new processors has almost peaked, and while new architectures provide small improvements to existing programs, this only helps slightly. To write efficient software, you now have to know how to program by making good use of the available computing resources, and this book will teach you how to do that. The Art of Efficient Programming covers all the major aspects of writing efficient programs, such as using CPU resources and memory efficiently, avoiding unnecessary computations, measuring performance, and how to put concurrency and multithreading to good use. You'll also learn about compiler optimizations and how to use the programming language (C++) more efficiently. Finally, you'll understand how design decisions impact performance. By the end of this book, you'll not only have enough knowledge of processors and compilers to write efficient programs, but you'll also be able to understand which techniques to use and what to measure while improving performance. At its core, this book is about learning how to learn.

Section 1 – Performance Fundamentals

In this section, you will learn about the methodology for studying the performance of programs, which is based on measurements, benchmarking, and profiling. You will also study the main hardware components that determine the performance of each computing system: the processors, the memory, and their interactions.

This section comprises the following chapters:

  • Chapter 1, Introduction to Performance and Concurrency
  • Chapter 2, Performance Measurements
  • Chapter 3, CPU Architecture, Resources, and Performance Implications
  • Chapter 4, Memory Architecture and Performance
  • Chapter 5, Threads, Memory, and Concurrency
