Maya Posch is a software engineer by trade and a self-professed electronics, robotics, and AI nut, running her own software development company, Nyanko, with her good friend, Trevor Purdy, where she works on various game development projects and some non-game projects. Apart from this, she does various freelance jobs for companies around the globe. You can visit her LinkedIn profile for more work-related details.

Aside from writing software, she likes to play with equations and write novels, such as her awesome reimagining of the story of the Nintendo classic, Legend of Zelda: Ocarina of Time, and the survival-horror novel she recently started, Viral Desire. You can check out her Scribd profile for a full listing of her writings.

Maya is also interested in biochemistry, robotics, and reverse-engineering of the human body. To know more about her, visit her blog, Artificial Human. If there's anything she doesn't lack, it has to be sheer ambition, it seems.

Louis E. Mauget learned to program a long time ago at the Michigan State University as a physics major learning to use software in designing a cyclotron. Later, he worked for 34 years at IBM. He went on to work for several consulting firms, including a long-term engagement with the railroad industry. He is currently consulting for Keyhole Software at Leawood, Kansas.

Lou has coded in C++, Java, JavaScript, Python, and newer languages, as each was conceived. His current interests include reactive functional programming, containers, Node JS, NoSQL, geospatial systems, mobile, and so on, in any new language or framework.

He occasionally blogs about software technology for Keyhole Software. He has coauthored three computer books and authored two IBM DeveloperWorks XML tutorials and a WebSphere Journal LDAP tutorial. Lou co-wrote several J2EE certification tests for IBM. He has also worked as a reviewer for Packt Publishing and others.

Multithreaded applications execute multiple threads in a single processor environment, to achieve . Filled with practical examples, this book will help you become a master at writing robust concurrent and parallel applications in C++. In this book, you will delve into the fundamentals of multithreading and concurrency and find out how to implement them. While doing so, you will explore atomic operations to optimize code performance and also apply concurrency to both distributed computing and GPGPU processing.

, Revisiting Multithreading, summarizes multithreading in C++, revisiting all the concepts you should already be familiar with and going through a basic example of multithreading using the native threading support added in the 2011 revision of C++.

, Multithreading Implementation on the Processor and OS, builds upon the fundamentals provided by the hardware implementations discussed in the preceding chapter, showing how OSes have used the capabilities to their advantage and made them available to applications. It also discusses how processes and threads are allowed to use the memory and processor in order to prevent applications and threads from interfering with each other.

, C++ Multithreading APIs, explores the wide variety of multithreading APIs available as OS-level APIs (for example, Win32 and POSIX) or as provided by a framework (for example, Boost, Qt, and POCO). It briefly runs through each API, listing the differences compared to the others as well as the advantages and disadvantages it may have for your application.
