Hi all, Some time ago there was some talk about improving Qt's multithreading API. I'm summarizing them here to stop them from fading into obscurity, and to see if there's any interest in following them up.
Here are the tasks mentioned: - Replace/Rewrite QtConcurrent [2] - Create/Find a good API to replace QtConcurrent::run() for "one-shot" tasks [1] - Find a third-party solution for high-level multithreading [2] - Find more uses for QFuture, outside of QtConcurrent [3] - Influence C++1y by creating a nice multithreading API [4] Some suggestions were raised: - Put a Qt-ish wrapper around TBB [1] - Integrate ThreadWeaver back into Qt? [2] Separately, someone was experimenting with ways to spawn a QObject in a secondary thread, without first constructing it in the current thread [5] Do you think any of these avenues are worth pursuing? I've had a quick look at TBB vs. ThreadWeaver. The latter specializes in task-oriented programming, while TBB is a more swiss-army-knife toolkit, which includes container-based operations similar to QtConcurrent. So, if we're to integrate 3rd-party option into Qt, TBB would be more worth it (although it'd involve more work too) Regards, Sze-Howe [1] http://lists.qt-project.org/pipermail/development/2012-November/007901.html [2] http://lists.qt-project.org/pipermail/development/2012-November/007921.html [3] http://lists.qt-project.org/pipermail/development/2012-November/007944.html [4] http://lists.qt-project.org/pipermail/development/2012-November/007933.html [5] http://lists.qt-project.org/pipermail/interest/2013-January/005740.html _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
