Another Parallel Extensions screencast

Daniel Moth is on a roll.  Two weeks ago he created three great overview screencasts for Parallel Extensions to the .NET Framework.  Today, he released a fourth video, covering the Task and TaskManager classes.  Thanks, Daniel!  We'll get this added to the MSDN Parallel Computing developer center soon, but in the meantime, ...

Code Snippets for Parallel.For and Parallel.ForEach

Introduced in Visual Studio 2005, Code Snippets allow you to quickly insert reusable blocks of code into your project.  For example, if you want to quickly write a for loop in C#, you can simply type "for" into your code file, and IntelliSense shows you the "for" code snippet: Now you press the tab key twice, and Visual ...

MSDN Forums

There are some great discussions going on over at the Parallel Extensions forum on MSDN.  Download the CTP, try out the bits, head on over to the forums, and get involved!  We'd love to hear from you...

Chunk partitioning vs range partitioning in PLINQ

If you look in the PLINQ samples in the December 2007 CTP, you'll see a parallel implementation of Luke Hoban's LINQ ray tracer.  The sample parallelizes the ray tracer by changing very few lines of code.   Luke's original query started as follows: from y in Enumerable.Range(0, screenHeight)For our sample, we've changed that to...

New “Parallel Computing” dev center on MSDN

There's a new Parallel Computing developer center on MSDN: "Microsoft’s Parallel Computing developer center is dedicated to providing information, ideas, community, and technology to developers to make it easier to write programs that perform and scale well on parallel hardware."  Check it out!  There are already a plethora of ...

PLINQ changes since the MSDN Magazine article

I posted about changes we've made to the Task Parallel Library since we published the MSDN Magazine article outlining its design.  In this post, I'll do the same thing for PLINQ.  Most of the October 2007 article on PLINQ is still accurate.   After all, PLINQ is largely an implementation of the .NET Standard Query Operators...

Task Parallel Library changes since the MSDN Magazine article

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 ...

CTP Quality

Community Technology Preview (CTP) releases from Microsoft typically provide early looks at the technologies a team is working on.  Frequently, CTP quality is nowhere near what folks might expect from Beta releases and the like, and that's ok.  The idea is to give all of you in the community a look at what we're working on, giving ...

Welcome to the Parallel Extensions team blog!

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, &...
