It’s been a few months since April when we last released a Community Technology Preview (CTP) of System.Threading.Tasks.Dataflow.dll, aka “TPL Dataflow”. Today for your programming pleasure, we have another update.As mentioned in “What’s New for Parallelism in .NET 4.5”, System.Threading.Tasks.Dataflow.dll ...
[Updated 5/17/2012 for Visual Studio 11 Beta] In Visual Studio 11 Beta, C++ AMP enables you to accelerate your applications using heterogeneous hardware such as GPUs. If you are a .NET developer, you can still use C++ AMP in your applications. You’ll write most of your code in C#, the pieces to execute on the GPU in C++ AMP, and then use your...
Thanks to everyone who attended my two talks at BUILD this past week, and I hope you enjoyed the sessions! For those of you unable to attend in person, the recordings of the talks are now available on Channel9: There were hundreds of other sessions this week at BUILD, and you can find their videos here: https://channel9.msdn.com/Events/BUI...
.NET 4 and Visual Studio 2010 saw the introduction of a wide range of new support for parallelism: the Task Parallel Library (TPL), Parallel LINQ (PLINQ), new synchronization and coordination primitives and collections (e.g. ConcurrentDictionary), an improved ThreadPool for handling parallel workloads, new debugger windows, new concurrency visualiz...
So many of you have asked about it, and it's finally here. You can now download the RC SDK and Developer Runtime of Silverlight 5, which includes TPL Tasks! https://10rem.net/blog/2011/09/01/silverlight-5-rc-now-available http://www.silverlight.net/downloads
Parallelism is all about performance. After all, in the majority of cases, introducing parallelism into code adds some level of complexity, and the primary reason we’re ok with that additional complexity is because we get great performance enhancements as a result. As such, as we develop our parallel runtimes and libraries to help...
Several times recently, folks have asked how to use tasks to implement the APM pattern, otherwise known as the Asynchronous Programming Model pattern, or the IAsyncResult pattern, or the Begin/End pattern. While moving forward we encourage folks to use a Task-based pattern for exposing asynchronous operation, the APM pattern has been the prev...
Sorting is one of the most fundamental problems in software algorithms; there are many sequential sorting algorithms with different time and memory complexities, but when it comes to parallel sort, things get more complicated. I will explain a simple and scalable algorithm to write a parallel sort using the .NET 4.0 System.Threading.Barrier synchro...
When .NET 4 was launched, we blogged about several case studies published regarding usage of .NET 4 to parallelize applications. Quite recently, several additional case studies have been published. I love reading these in order to better understand how folks are applying this technology, and parallelism in general, to improve their solu...
One important fact to know about static constructors is that they effectively execute under a lock. The CLR must ensure that each type is initialized exactly once, and so it uses locking to prevent multiple threads from executing the same static constructor. A caveat, however, is that executing the static constructor under a loc...
