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.What you will learnDiscover how to use the hardware computing resources in your programs effectivelyDiscover how to use the hardware computing resources in your programs effectivelyUnderstand the relationship between memory order and memory barriersUnderstand the relationship between memory order and memory barriersFamiliarize yourself with the performance implications of different data structures and organizationsFamiliarize yourself with the performance implications of different data structures and organizationsAssess the performance impact of concurrent memory accessed and how to minimize itAssess the performance impact of concurrent memory accessed and how to minimize itDiscover when to use and when not to use lock-free programming techniquesDiscover when to use and when not to use lock-free programming techniquesExplore different ways to improve the effectiveness of compiler optimizationsExplore different ways to improve the effectiveness of compiler optimizationsDesign APIs for concurrent data structures and high-performance data structures to avoid inefficienciesDesign APIs for concurrent data structures and high-performance data structures to avoid inefficienciesWho this book is forThis book is for experienced developers and programmers who work on performance-critical projects and want to learn new techniques to improve the performance of their code. Programmers in algorithmic trading, gaming, bioinformatics, computational genomics, or computational fluid dynamics communities will get the most out of the examples in this book, but the techniques are fairly universal. Although this book uses the C++ language, the concepts demonstrated in the book can be easily transferred or applied to other compiled languages such as C, Java, Rust, Go, and more.Table of ContentsIntroduction to Performance and ConcurrencyIntroduction to Performance and ConcurrencyPerformance MeasurementsPerformance MeasurementsCPU Architecture, Resources, and Performance ImplicationsCPU Architecture, Resources, and Performance ImplicationsMemory Architecture and PerformanceMemory Architecture and PerformanceThreads, Memory, and ConcurrencyThreads, Memory, and ConcurrencyConcurrency and PerformanceConcurrency and PerformanceData Structures for ConcurrencyData Structures for ConcurrencyConcurrency in C++Concurrency in C++High-Performance C++High-Performance C++Compiler Optimizations in C++Compiler Optimizations in C++Undefined Behavior and PerformanceUndefined Behavior and PerformanceDesign for PerformanceDesign for Performance
