Book Description

Julia is a high-level, high-performance dynamic programming language for numerical computing. It was created to solve the dilemma between high-level slow code and fast but low-level code, and the necessity to use both to achieve high performance.

If you want to understand how to avoid bottlenecks, and design your program for the highest possible performance, then this book is for you.

Julia High Performance will take you on a journey to understand the performance characteristics of your Julia programs, and enables you to utilize the promise of near C levels of performance in Julia. In this book, you will also see how Julia uses type information to achieve its performance goals, and how to use multiple dispatches to help the compiler to emit high performance machine code. Numbers and their arrays are obviously the key structures in scientific computing - you will see how Julia's design makes them fast. Towards the end, you will get a taste of Julia's multithreading and distributed computing capabilities.

By the end, you will have the ability to build large scale high performance Julia applications, design systems with focus on speed, and improve performance of existing codebases.
