Boost.Thread enables the use of multiple threads of execution with shared data in portable C++ code.

Boost.Thread enables the use of multiple threads of execution with shared data in portable C++ code. It provides classes and functions for managing the threads themselves, along with others for synchronizing data between the threads or providing separate copies of data specific to individual threads.

The Boost.Thread library was originally written and designed by William E. Kempf. For Boost 1.35+, Anthony Williams performed a major rewrite designed to closely follow the proposals presented to the C++ Standards Committee, in particular N2497, N2320, N2184, N2139, and N2094.

As of Boost version 1.50.0 Boost.Thread provides an almost complete implementation of the C++ 2011 Threads library, plus extensions such as shared locks and thread interruption.

Can mutex implementations be interchanged (independently of the thread implementation)

Do all mutex implementations ultimately call the same basic system/hardware calls - meaning that they can be interchanged? Specifically, if I'm using __gnu_parallel algorithms (that uses openmp) and I want to make the classes they call threadsafe…

Upgrade shared_lock to unique lock usage, timing and design

I am updating a code that previously uses its own read and write lock mechanism (this code was written prior to C++11 and std::shared_mutex does not exist yet) to use the std version of C++. There is two classes named ReadLock and WriteLock, and…

Signals and threads - good or bad design decision?

I have to write a program that performs highly computationally intensive calculations. The program might run for several days. The calculation can be separated easily in different threads without the need of shared data. I want a GUI or a web…

Both blocking and non blocking queue

I need to set up a producer-consumer scheme with two threads linked by a queue (the producer pushing tasks into the queue, the consumer executing them as they come). Since the queue will be empty most of the time I must make it so that the consumer…

I have some code with which I'm trying to make a shared memory segment. This segment is managed, on this end, from within a class. The shared segment will be used in a "bulletin board" fashion. That is, this one process will write to it, and many…

Multi-threaded C++ Message Passing

I am tasked to modify a synchronous C program so that it can run in parallel. The goal is to have it be as portable as possible as it is an open source program that many people use. Because of this, I thought it would be best to wrap the program in…
