Qt Concurrent is a C++ template library for writing multi-threaded applications.
Qt Concurrent provides high-level APIs that makes it possible to write multi-threaded
programs withouth using low-level threading primitives such as
critcal sections, mutexes or wait conditions.
Programs written with Qt Concurrent automaticallly adjust the number of
threads used according to the number of processor cores available. This
means that applications written today will continue to scale when deployed
on multi-core systems in the future.
The library includes functional programming style APIs for for parallel list prosessing, a MapReduce
implementation for shared-memory (non-distributed) systems, and classes
for managing asynchronous computations in GUI applications.
Some people have been asking how to embed Qt painted content (and especially Qt widgets) in a 3d scene. As I’ve been wanting to do this ever since we added QTransform supporting fully projective transformations, I sat down and wrote a small example demonstrating these capabilities. With no further delay, I present WolfenQt:
Here’s a screenshot […]
For the past 2 weeks, I’ve been wrestling with a fix for task 208487. At first glance, it seems pretty far-fetched (at least it did to me): an application that has 2 billion running timers and runs out of timer ids. But then I went and looked at the code (that I wrote!) and […]
The Wide Finder Project is an informal parallel programming competition where the task is to compute web site statistcs from a 218-million line access log. Each entry will be benchmarked on a Sun T2000 with support for 32 hardware threads, giving lots of opportunities for parallel processing.
What makes this really interesting is that the project […]
So the time is finally here. Qt 4.4.0 was released a few weeks ago and as promised Qt Jambi is right behind. A lot of effort has gone into this one, in addition to supporting all the new Qt features, like Phonon, Webkit, Widgets in Graphics View, XQuery and Qt Concurrent, we also have a […]
Just a quick update to say that Qt Concurrent has been integrated into Qt/main and is now available in the snapshots. The documentation is available here, end there’s a couple of examples in the examples/qtconcurrent/ directory in the snapshot package. Enjoy!
