Software is headed for a fundamental change. Over the last 30 years, developers have relied on exponential growth in computing power in order to dream big. Your cool new application is too slow today? No problem, just wait two years and everyone will have computers that run twice as fast. But as Herb Sutter wrote, &...
It's been a hectic and exciting few weeks, and we on the Parallel Computing Platform team have been having a great time talking with customers all over the world, at the PDC, at TechEd EMEA, at DevConnections, through Channel 9, and more. A lot of the resulting material is now available online for viewing, so do check it out if you're ...
We've received several questions on the MSDN Forums for Parallel Extensions about the performance of the Parallel class, and specifically of the loop constructs we provided in the CTP. We're very much aware that the performance of Parallel.For/ForEach in the CTP is not optimal, and that for some situations, the overhead for these ...
When teaching recursion in an introductory computer science course, one of the most common examples used involves a tree data structure. Trees are useful in this regard as they are simple and recursive in nature, with a tree's children also being trees, and allow for teaching different kinds of traversals (in-order, pre-order, post-...
The core entity in the Task Parallel Library around which everything else revolves is System.Threading.Tasks.Task. The most common way of creating a Task will be through the StartNew method on the TaskFactory class, a default instance of which is exposed through a static property on Task, e.g. var t = Task.Factory.StartNew(() => { &...
Along with the release of the .NET Framework 4 Beta 1, we've just published a slew of samples that demonstrate using Parallel Extensions in a variety of ways. You can download these from Code Gallery at https://code.msdn.microsoft.com/ParExtSamples.These samples include raytracers, a sudoku game, an image colorization algorithm, solvers ...
Back in the October 2007 issue of MSDN Magazine, we published an article on the beginning stages of what has become the Task Parallel Library (TPL) that's part of the Parallel Extensions to the .NET Framework. While the core of the library and the principles behind it have remained the same, as with any piece of software in the ...
A few weeks ago, I presented on Parallel Extensions to the .NET Framework at the 6th annual Microsoft Financial Services Developer Conference (the decks from the conference are now available online). I had a great time and a great audience, and during the presentation on Thursday I received some good questions. Here are some of ...
In addition to the Betas of Visual Studio 2010 and the .NET Framework 4 being available for download today, the MSDN documentation for .NET 4 Beta 1 is also available. This includes quite a bit of useful information about the new parallelism constructs. Here's a summary of the relevant material, with links: Related to...
PLINQ is a very cool technology, and I believe it will prove useful for parallelizing operations in a wide range of important scenarios. Moreover, I believe that the programming model it provides will enable a wide-range of developers to easily take advantage of concurrency in their applications. However, one of the risks ...
