POSIX

• Computers: Software: Operating Systems: POSIX  (2)

Threads   - The Open Group Base Specifications Issue 6 (IEEE Std 1003.1, 2004 Edition) chapter for threads. Includes manual pages of all POSIX thread functions.

GNU Pth - Portable Threads: portable POSIX/ANSI-C library for Unix gives non-preemptive priority-based scheduling for multithreading in programs. All threads run in same address space, each has its own program counter, run time stack, signal mask, errno variable; cooperative scheduling: threads dispatched based on priority, pending events. [Open Source, GPL]

Introduction to Programming Threads - Introduces what threads are, why they are useful and how to program with them using the POSIX 1003.1c thread standard and API bindings for C.

LinuxThreads FAQ - Frequently asked questions about the kernel-level multi-threading library for Linux.

Multi-Threaded Programming with POSIX Threads - Attempts to show how the library's features can be used in "real-life" programs. It explains the different tools defined by the library, shows how to use them, and then gives an example of using them to solve programming problems.

Multithreaded Programming with Pthreads - In addition to scheduling, synchronization and signal handling special emphasis is placed on cancellation, error expedition, performance, hardware and languages. (Daniel J. Berg, Bil Lewis)

Multithreading in the Solaris Operating Environment - Describes the new thread implementation of the Solaris 9 Operating Environment which adopted a highly tuned and tested "1:1" thread model in preference to the historic "MxN" implementation. [PDF]

Native POSIX Thread Library: NPTL - White paper describes actual implementation of thread library for which requirements are spelled out in a prior document. Many things are different. [PDF]

POSIX Synchronous Wrappers - A set of C++ wrappers for posix synchronous entities such as pthread, mutexes and condition.

POSIX Threads Explained, Part 1 - How to use POSIX threads to increase the responsiveness and performance of your code.

POSIX Threads Explained, Part 2 - How to protect the integrity of shared data structures in threaded code by using mutexes.

POSIX Threads Explained, Part 3 - How to use condition variables.

POSIX Threads on HP-UX 11i - Provides an overview of the thread model implementation on HP-UX 11i and describes the impact that each thread model has on application behavior and performance. [PDF]

POSIX Threads Programming - Provides an overview of threads programming and the POSIX threads API.

POSIX Threads Tutorial - How to write parallel applications using POSIX threads. By Mark Hays.

Semaphores in Linux - An explanation of semaphores under Linux, including a comparison of System V and POSIX style semaphores. Code examples show how semaphores are used. (May 24, 2007)

An Introduction to POSIX Threads - This article demystifies the POSIX thread interface, providing practical examples of threaded code for consideration. (January 21, 2004)

Native POSIX Thread Library (NPTL) 0.1 Released - Initial performance: 8x Linux Threads, 4x NGPT. [Linux Weekly News] (September 19, 2002)

Multithreaded Programming (pthreads Tutorial) - Dives into the world of threads with a little bit of "theory" first. Examine thread synchronization primitives and how to use POSIX pthreads. Finally, it finishes off with thread performance and a brief overview of multiprocess programming. (August 20, 2002)
