用于C ++的独立于平台的并发编程库

Question

I am familiar with concurrent programming in Java which provides a lot of tools for this. However, C++ concurrent programming isn't so easy to start using.

What is the best way to start programming concurrently on C++? Are there any nice libraries which wrap concurrent programming primitives and provide you with more high-level constructs?

I tried QtConcurrent which provides you with nice MapReduce functionality but it is heavily biased towards concurrent computation using Qt so it's not a good choice if you don't want to use Qt.

Are there any other similar libraries? What do people use here?

Thanks for your help in advance, sneg

Answer 1

There are several choices:

ACE which provides some concurrency constructs

Intel Threading Building Blocks

boost::threads

OpenMP

Qt Threading libraries

Answer 2

Morendil's suggestion (CSP - communicating sequential processes) is truly interesting to take a look at - it's a very different view of threading and one that works well once you wrap your head around it. I first encountered it in the rather esoteric Occam language for Transputers, but the idea has stuck with me.

A more conventional idea: boost::threads work quite well for building thread-based concurrent programs. It's quite low level though.

OpenMP is at a higher level than threads and also quite well-supported.

Answer 3

You could look at CSP , which has a C++ implementation. Way different from Java's threading primitives, though.

Answer 5

Intel's Threading Building Blocks is great for introducing concurrency at the level of individual data-parallel loops, and it takes care of managing threads and allocating work automagically. It can be used in similar ways to OpenMP, but without the need for explicit compiler support.
