Boby George and Pooja Nagpal - testers on the Parallel Computing Platform team responsible for the parallel programming support in .NET 4- built a parallel spell checker algorithm and used the Concurrency Visualizer to analyze and improve the performance and scalability of their implementation.Optimizing Parallel Applications Using Concurrency...

In order to execute parallel queries as efficiently as possible, Parallel LINQ (PLINQ) treats ordering as optional. By default, PLINQ considers sequences to be unordered, unless the user explicitly opts into maintaining ordering using either the AsOrdered or the OrderBy operator.Roy Patrick Tan wrote a detailed article that expl...

With TPL, there are several ways to create and start a new task.  One way is to use the constructor for task followed by a call to the Start method, e.g.        new Task(...).Start();and the other is by using the StartNew method of TaskFactory, e.g.        Task.Factory.StartNew(....

I'm going to be in Manhattan on June 29th, and while there I'll be presenting to a joint meeting of the NYC .NET Developer's Group and the New York ALT.NET Group on parallel programming with .NET 4 and Visual Studio 2010.  Details are available here, and I'll look forward to seeing you there!Thanks!Stephen

Are you attending TechEd in New Orleans this week?  If so, check out the multitude of parallel computing-related breakout sessions, including: The first two (DEV314 and DEV317) are being presented by Huseyin Yildiz, one of the primary developers on the Parallel Computing Platform team responsible for the Task Parallel Library.En...

We’ve been very excited about the new debugging windows in Visual Studio 2010, namely Parallel Tasks and Parallel Stacks, as well as the newly revamped Threads window, and thus we’ve talked about them quite a bit. For an overview, you can read the MSDN Magazine article at https://msdn.microsoft.com/en-us/magazine/ee410778.aspx, and Daniel Moth has ...

For a relatively advanced feature, I've been surprised how often this question has come up recently. When a task completes, its continuations become available for execution, and by default, a continuation will be scheduled for execution rather than executed immediately.  This means that the continuation has to be queued to the scheduler a...

(The full set of ParallelExtensionsExtras Tour posts is available here.) The Task Parallel Library isn’t just about CPU-bound operations.  The Task class is a great representation for any asynchronous operation, even those implemented purely as asynchronous I/O.Task’s ability to represent arbitrary asynchronous operations without...

(The full set of ParallelExtensionsExtras Tour posts is available here.)The Task Parallel Library provides the Task.Wait method, which synchronously waits for the target Task to complete.  If the Task completed successfully, the method simply returns.  If the Task completed due to an unhandled exception or cancellation, Wait throws an app...

In a previous post, we introduced the UnobservedTaskException event, saying that it would be useful for host-plugin scenarios where a host application should continue to execute in the presence of exceptions thrown by buggy plugins.  A typical example is an Internet browser; should the entire application crash if some rich content plugin crash...
