C++ master/worker

Question

I am looking for a cross-platform C++ master/worker library or work queue library. The general idea is that my application would create some sort of Task or Work objects, pass

Answer 1

I think this calls for intel's Threading Building Blocks, which pretty much does what you want.

Answer 2

See this post for creating threads using the boost library in C++:

Simple example of threading in C++

(it is a c++ thread even though the title says c)

basically, create your own "master" object that takes a "runnable" object and starts it running in a new thread.

Then you can create new classes that implement "runnable" and throw them over to your master runner any old time you want.

Answer 3

Check out Intels' Thread Building Blocks library.

Answer 4

Sounds like you require some kind of "Time Sharing System".

There are some good open source ones out there, but I don't know
if they have built-in QT slot support.

Answer 5

I haven't used it in long enough that I'm not positive whether it exactly meets your needs, but check out the Adaptive Communications Environment (ACE). This library allows you to construct "active objects" which have work queues and execute their main body in their own threads, as well as thread pools that can be shared amoung objects. Then you can pass queue work objects on to active objects for them to process. Objects can be chained in various ways. The library is fairly heavy and has a lot to it to learn, but there have been a couple of books written about it and theres a fair amount of tutorial information available online as well. It should be able to do everything you want plus more, my only concern is whether it possesses the interfaces you are looking for 'out of the box' or if you'd need to build on top of it to get exactly what you are looking for.

Answer 6

This is probably a huge overkill for what you need but still worth mentioning -
BOINC is a distributed framework for such tasks. There's a main server that gives out tasks to perform and a cloud of workers that do its bidding. It is the framework behind projects like SETI@Home and many others.
