• Focuses on the POSIX multithreading model, making comparisons to OS/2 and Win32 throughout.

  • Contrasting POSIX API to the OS/2 and Win32 APIs gives the programmer a feeling for what kind of porting issues might be involved when writing to more than one of these libraries.

• Promotes MT programming as a means for writing better programs more easily, and for having programs that run faster with fewer bugs.

• Provides an introduction to the underlying structures upon which threads are built, the construction of the threads themselves, and the operating system support that allows efficient implementation.

• Details the different scheduling models and the various alternative choices that could be made.

  • Describes context switching in detail.

  • Delves into the details of the various POSIX options and parameters.

• Discusses hardware — cache architectures, interconnect topologies, atomic instructions, invalidation techniques.

• Includes several complete programs which are presented as examples.

  • Details and issues of the threads used are discussed.

  • References to other programs on the net are made.

• Covers the cancellation of unwanted threads.

Based on the best-selling Threads Primer, Multithreaded Programming with Pthreads gives you a solid understanding of Posix threads: what they are, how they work, when to use them, and how to optimize them.

It retains the clarity and humor of the Primer, but includes expanded comparisons to Win32 and OS/2 implementations. Code examples tested on all of the major UNIX platforms are featured along with detailed explanations of how and why they use threads.

In addition to scheduling, synchronization, signal handling, etc., special emphasis is placed on:

• Cancellation: What does it mean to do bounded-time cancellation? What are the numerous details the programmer must deal with, and how do you avoid using cancellation at all?
• Error expeditions: What do they all mean and what should you do about them?
• Performance: How fast can a program run, and what are the limiting factors? Theoretical issues are considered and a case study for NFS is presented.
• Hardware: A number of machine designs are examined (Sun, SGI, and DEC), focusing on issues of performance, synchronization instructions, bus design, and invalidation techniques.
• Languages: The use of threads in other languages (Lisp, Eiffel, Smalltalk, etc.) is examined, with special emphasis on C++ and Java.
• References: Pointers to the newsgroup, FAQs, web pages, code examples, other books, freeware tools, and commercial products are included.
• More than anything else this is a practical book-it tells you what can and cannot be done with threads and why. In short, everything you need to know to build faster, smarter, multithreaded applications.
