We will learn how to create threads, coordinate between threads, share data between threads, and stop threads. This means that the present-day computer has the ability to multitask. We will expand our image processing application to implement these two patterns in combination. To perform a break or a stop of a parallel loop, we need to use the ParallelLoopState. Chapter 2, Looking at Multithreaded Classes — BackgroundWorker, enables us to examine the basics of multithreaded programming with the BackgroundWorker class.

Data Parallelism Parallel loop processing How to do it How it works Data parallelism on collections using Parallel. He is keen on improving the experience of software developers around the globe as well as pushing the limits of technology to enable the developers themselves to become better.
It is the central control of the Task Parallel Library. If you find a mistake in one of our books—maybe a mistake in the text or the code—we would be grateful if you could report this to us. We will use tasks, task factories, and parallel loops to develop multithreaded applications at a higher level than directly creating and managing individual threads. Chapter 4, Advanced Thread Processing, explains in detail the concept of heavyweight concurrency and working with multiple threads using the Thread class. The Asynchronous Programming Model Introduction to the Asynchronous Programming Model How to do it How it works Using an AsyncCallback delegate method How to do it How it works The async and await keywords How to do it How it works Summary Index C Multithreaded and Parallel Programming C Multithreaded and Parallel Programming Copyright © 2014 Packt Publishing All rights reserved.

However, to fully exploit this in your applications, you need to write multithreading code. Instant updates on new Packt books Get notified! In his career, which includes more than 10 years of professional experience, he worked on desktop, mobile, and web projects—many of them at the enterprise level. Most modern machines have dual-core processors. If you need to update older applications with today's latest. Here, you can search, access, and read Packt's entire library of books. Chapter 9, Pipeline and Producer-consumer Design Patterns, helps us explore two of the most popular parallel patterns for development—Pipelining and producer-consumer.
Ahmed has worked for a number of clients and employers. With Safari, you learn the way you learn best. Danijel worked for numerous clients ranging from the manufacturing sector to medical services to taxes. Find out when new books are published by following PacktEnterprise on Twitter or the Packt Enterprise Facebook page. Using multiple cores means your applications can process data faster and be more responsive to users. This means that the present-day computer has the ability to multitask.
It is very similar to a thread but with a higher level of abstraction and functionality built around it. We will further examine additional topics with the Task Parallel Library and task parallelism. We will begin by covering some techniques that have been around since the beginning of. During this chapter, we will walk through a simple single-threaded and then multithreaded example to show how performance is improved. However, to fully exploit this in your applications, you need to write multithreading code. The following are the interesting aspects of his profession: He has experience integrating multiple platforms and products He helps organizations gain a deeper understanding and value of their current investments in data and existing resources, turning them into useful sources of information He has improved, salvaged, and architected projects by utilizing unique and innovative techniques His hobbies include practicing yoga and scuba diving.

He relocated to Los Angeles to pursue his goal of working in the video game industry. Recently, he acquired a degree in game programming from the University of Advancing Technology after getting transferred from Arizona State University, where he studied computer science. This chapter will explore the idea of heavyweight concurrency versus lightweight concurrency, which will be explained in detail later in the book. This chapter will further expand the image processing application to demonstrate how to coordinate between threads and wait on threads to complete by avoiding deadlocks, locking, and error handling. PacktLib is Packt's online digital book library.
Working with multiple BackgroundWorker components How does it work? We will then go through the different classes provided by the. I would like to offer one last thank you to all of the people at Fellowship Hall, especially Mike and Mahala, who helped save my life and taught me that miracles do happen as long as you show up and do your part. His great reputation has resulted in a large client base for his consultancy company, Sandler Ltd. We will demonstrate using the Threads view, and the Tasks, Parallel Stacks, and Parallel Watch windows. However, to fully exploit this in your applications, you need to write multithreading code. He is frolicsome and free-minded.

I would also like to thank my client base and especially Microsoft Corporation and my colleagues over there for enabling me to become a reputable leader as a software developer in the industry, which is my joy, passion, and pride. Chapter 3, Thread Class — Heavyweight Concurrency in C , allows us to examine and work with the Thread class and namespace. Errata Although we have taken every care to ensure the accuracy of our content, mistakes do happen. After leaving Microsoft, he ventured into setting up his own consultancy company, offering the best possible solutions for a variety of industries and providing real-world answers to those problems.
This book is for developers looking to expand their toolbox with all of the techniques and methods available in. Chapter 8, Debugging Multithreaded Applications with Visual Studio, teaches us how to take full advantage of Visual Studio 2012 to debug our multithreaded applications. Let's start by creating and executing a task. Chapter 6, Task-based Parallelism, enables us to examine the Task Parallel Library and task parallelism. A task is an asynchronous set of operations that can be run concurrently with other tasks.
