Throughout the development of Parallel Extensions for the .NET Framework 4, we’ve come across a myriad of situations where certain functionality would be useful in developing a particular application or library, but where that functionality isn’t quite encapsulated in the bits we’re shipping.  Sometimes this functionality is ...

Microsoft Developer & Platform Evangelism, in collaboration with the Microsoft Parallel Computing Platform product team, is hosting a developer lab at the Platform Adoption Center on April 12-15, 2010.  This event is for Microsoft Partners and Customers seeking to incorporate either .NET Framework 4 or Visual C++ 2010 parallelism feat...

I previously posted in November about a paper I'd written on patterns for parallel programming.  The original paper had over 200 snippets of C# code to demonstrate and exemplify the ideas being discussed.  Due to popular demand (and in honor of the many Visual Basic MVPs on campus this week for the MVP Summit), we've now posted another ve...

We’re hiring! If you're reading this post, you most likely have an interest in parallel or distributed computing, writing concurrent software, and the like.  Take that interest a step further, and help us make the manycore era a successful reality by coming to work on the Parallel Computing Platform team at Microsoft.We currently have se...

The F# team has released the F# PowerPack for download on CodePlex, and we're very excited that the PowerPack now has direct support for PLINQ.  From the CodePlex site: F# Parallel LINQ IntegrationFSharp.PowerPack.Parallel.dll provides an F#-style API for parallel operations on sequences that are part of .NET 4.0 as System.Linq.ParallelEnumera...

Igor Ostrovsky is a developer on the Parallel Extensions team.  On his blog, he's documented a great set of examples for how caches can affect application performance; this is important to think through when writing parallel applications, but as Igor demonstrates, it applies equally to serial applications.  Check out his post.

Are you using Parallel LINQ (PLINQ), the Task Parallel Library (TPL), or any of the new coordination and synchronization primitives in .NET 4 (or in the Parallel Extensions June 2008 CTP or with the recent Reactive Extensions release)?  Are you planning to use or are you already using this support in a production application or libra...

Are you using the CCR (Microsoft Robotics' "Concurrency & Coordination Runtime") today in production applications or libraries, and in particular for non-robotics purposes?  If so, we’d love to hear about your experiences, and any and all information you’re willing to share would be very welcome.  What do you like about it...

ConcurrentDictionary<TKey,TValue> is a new type in the .NET Framework 4, living in the System.Collections.Concurrent namespace.  As noted in the MSDN documentation, ConcurrentDictionary “represents a thread-safe collection of key-value pairs that can be accessed by multiple threads concurrently.”  While ConcurrentDiction...

On Code Gallery, we have a plethora of samples that highlight aspects of the .NET Framework 4 that help with writing scalable and efficient parallel applications.  This post examines each of those samples, providing an overview of what each provides.
