C++ High Performance. Boost and optimize the performance of your C++17 code

Björn Andrist, Viktor Sehr

C++ is a highly portable language and can be used to write both large-scale applications and performance-critical code. It has evolved over the last few years to become a modern and expressive language. This book will guide you through optimizing the performance of your C++ apps by allowing them to run faster and consume fewer resources on the device they're running on without compromising the readability of your code base.The book begins by helping you measure and identify bottlenecks in a C++ code base. It then moves on by teaching you how to use modern C++ constructs and techniques. You'll see how this affects the way you write code. Next, you'll see the importance of data structure optimization and memory management, and how it can be used efficiently with respect to CPU caches. After that, you'll see how STL algorithm and composable Range V3 should be used to both achieve faster execution and more readable code, followed by how to use STL containers and how to write your own specialized iterators.Moving on, you’ll get hands-on experience in making use of modern C++ metaprogramming and reflection to reduce boilerplate code as well as in working with proxy objects to perform optimizations under the hood. After that, you’ll learn concurrent programming and understand lock-free data structures. The book ends with an overview of parallel algorithms using STL execution policies, Boost Compute, and OpenCL to utilize both the CPU and the GPU.

C++ High Performance. Master the art of optimizing the functioning of your C++ code - Second Edition

Björn Andrist, Viktor Sehr, Ben Garney

C++ High Performance, Second Edition guides you through optimizing the performance of your C++ apps. This allows them to run faster and consume fewer resources on the device they're running on without compromising the readability of your codebase.The book begins by introducing the C++ language and some of its modern concepts in brief. Once you are familiar with the fundamentals, you will be ready to measure, identify, and eradicate bottlenecks in your C++ codebase. By following this process, you will gradually improve your style of writing code. The book then explores data structure optimization, memory management, and how it can be used efficiently concerning CPU caches.After laying the foundation, the book trains you to leverage algorithms, ranges, and containers from the standard library to achieve faster execution, write readable code, and use customized iterators. It provides hands-on examples of C++ metaprogramming, coroutines, reflection to reduce boilerplate code, proxy objects to perform optimizations under the hood, concurrent programming, and lock-free data structures. The book concludes with an overview of parallel algorithms.By the end of this book, you will have the ability to use every tool as needed to boost the efficiency of your C++ projects.

Wysoce wydajny C++. Opanuj sztukę optymalizowania działania kodu. Wydanie II

Bjorn Andrist, Viktor Sehr

Dzisiejszy C++ jest wyjątkowym językiem programowania. Umożliwia pisanie zwięzłego, stabilnego kodu, który można zoptymalizować pod kątem wydajności w niespotykanym dotychczas stopniu. Język C++ w ciągu ostatnich lat został unowocześniony. W standardzie C++ 20 znalazło się sporo mechanizmów, które pozwalają osiągnąć wysoką efektywność kodu, a równocześnie uprzyjemniają programiście pracę. Poprawiono także ustawienia domyślne kompilatora. To wszystko sprawia, że wielu profesjonalistów wybiera właśnie C++, gdy chce uzyskać kod o wyjątkowej wydajności. Ta książka jest drugim, zaktualizowanym i uzupełnionym wydaniem przewodnika dla programistów. Rozpoczyna się od szczegółowego wprowadzenia do nowoczesnego C++ z uwzględnieniem technik eliminowania wąskich gardeł w kodzie bazowym. Następnie omówiono zagadnienia optymalizacji struktur danych i zarzadzania pamięcią. Przedstawiono również tematykę algorytmów, zasady pisania czytelnego kodu i stosowania niestandardowych iteratorów. Zamieszczono w niej też praktyczne przykłady używania metaprogramowania w języku C++, korutyn, refleksji (do ograniczenia ilości szablonowego kodu), obiektów pośredniczących (do wprowadzania ukrytych optymalizacji), programowania współbieżnego i struktur danych wolnych od blokad. W końcowej części dokonano przeglądu algorytmów równoległych w C++. W książce między innymi: nowe aspekty C++ 20 wyspecjalizowane struktury danych na potrzeby wydajnego kodu metaprogramowanie i niestandardowe zarządzanie pamięcią mechanizm refleksji i programowanie współbieżne bez używania blokad subtelne optymalizacje algorytmów z biblioteki standardowej C++ leniwe generatory i zadania asynchroniczne Twórz wydajny i czysty kod w C++!
