Paper :: Guide to Implementing Custom TPL Dataflow Blocks

TPL Dataflow includes a number of built-in, already-implemented blocks that target the most common scenarios.  Additionally, some flexibility is provided by the set of options that may be used to tweak block behaviors.  However, a developer may still choose to implement a custom block for advanced scenarios where the built-in ones are not sufficient.  Zlatko… Read more

Exception Handling in TPL Dataflow Networks

A “dataflow block” is represented by a class implementing the IDataflowBlock interface. The state of a dataflow block is represented by the state of its IDataflowBlock.Completion Task, which itself has a Status property. When a dataflow block is in active state, meaning that it is currently doing processing or may do more processing in the… Read more

What’s New For Parallelism in .NET 4.5

.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 visualizations, and more. Since then, we’ve been hard… Read more

Presentation on TPL Dataflow in financial applications

Matt Davey from Lab49 presented at the Waters North American Trading Architecture Summit April 2011 on using TPL Dataflow in trading solutions.  You can see his slide deck at http://www.slideshare.net/mattdotdavey/waters-north-american-trading-architecture-summit-april-2011. It’s awesome to see the technology being used effectively to help build these kinds of applications…. Read more
