Windows Server 2008 R2 and Windows 7 introduce new system-level features (e.g. User-Mode-Scheduling) that both the C++ Concurrency Runtime and the .NET Parallel Extensions extend.   Developers may easily target current and legacy platforms using the new runtime and extensions. 

First, a project is shown that counts the number of primes up to a given upper bound.  Each number is checked by seeing if it’s divisible by any number between 2 and its square root.  Each prime number found increases the count.  The main control is a standard for loop.

Next, the same code is converted to work with the new Parallel.For() method.  This takes the lower and upper bound, and a delegate for the action to take.  Using a Lamda expression, the original loop body is made to work using i => {} syntax.  When this code is run, it is clear that a bug has surfaced in the form of a bad prime count.  This is actually a common multithreading bug, stemming from the use of the increment operator, ++.  Using the Interlocked.Increment() method fixes the problem.

The next demo starts with a LINQ query and converts to a Parallel LINQ, or PLINQ, query.  After demonstrating the original loop which uses Enumerable.Range() to generate a range of numbers, it is shown that ParallelEnumerable.Range() creates an enumerator that is automatically multi-threaded.

Finally, to demonstrate a more general-usage solution, any IEnumerable collection can easily be parallelized using the expression method AsParallel().  Thus, a collection students of type List<Student> could be used in a LINQ as a parallel query by simply using it as students.AsParallel().

We'll look at some of the surface-area of the Parallel Extensions API and provide you with enough information to start working with it yourself in the Visual Studio 2010 CTP VPC.

Remember that we are running these bits within a virtual machine with a single virtual processor, so you won't be able to see the performance improvements from the library. However, you will be able to start get a feel for the API itself. In future episodes, we will dive into deeper details of the various parts of Parallel Extensions.

Also, in next week's episode, Jonathan Carter will be back to talk about another new feature in ASP.NET 4.0, so make sure to stay tuned for that!

It includes the Task Parallel Library (TPL), which provides imperative data and task parallelism; Parallel LINQ (PLINQ), which provides declarative data parallelism; and all new Coordination Data Structures (CDS), which provide support for work coordination and managing shared state.

In addition to CDS, this upgrade provides several improvements, including a new scheduler that is more robust, efficient, and scalable. TPL also exposes new functionality, including methods for continuations. PLINQ now runs on top of TPL, clarifies order-preservation, and provides several new operators.

The June CTP works with the .NET Framework 3.5 as a simple, small-footprint installation that drops a single DLL, documentation, samples, and registers the DLL with Visual Studio 2008.

Here, we continue the discussion with the key engineers of the Microsoft Parallel Computing Platform (which includes the Parallel Extensions for .NET...): Lead Developer Joe Duffy, Developer Huseyin Yildiz, Developer Igor Ostrovsky. Program Manager Stephen Toub and Program Manager Ed Essey.

We dig deeply into a lot of topics related to parallelism and conconcurency and how the new additions to the platform enable developers to exploit multi/many core processors in an elegant way.

TPL also exposes new functionality, including methods for continuations. PLINQ now runs on top of TPL, clarifies order-preservation, and provides several new operators. The June CTP&nbsp;works with the .NET Framework 3.5 as a simple, small-footprint installation that drops a single DLL, documentation, samples, and registers the DLL with Visual Studio 2008. Here, we meet some of the key engineers of the Microsoft Parallel Computing Platform (which includes the Parallel Extensions for .NET...): Lead Developer Joe Duffy, Developer Huseyin Yildiz, Developer Igor Ostrovsky, Program Manager Stephen Toub and Program Manager Ed Essey.We dig deeply into a lot of topics related to parallelism and conconcurency and how the new additions to the platform enable developers to exploit multi/many core processors in an elegant way.Enjoy part 1.

You've heard about the Parallel Computing Platform a few months ago in an interview with Anders Hejlsberg and Joe Duffy. We didn't go too deep in that talk. It was an introduction to the Parallel Computing Platform.

Here, we take a dive down into the technical rabbit hole with Daan, Joe, Stephen and Huseyin.

Daan is an MSR reseacher who's work has been instrumental in bringing TPL and Parallel Extensions to life. Of course, Joe is the guy who invented PLINQ (he wrote the original Think Week paper that impressed Bill) and is a lead developer on the Parallel Computing Platform team. Stephen is the Program Manager (and is the one driving and scheduling many of the interviews you will see covering Parallel Computing Platform here on C9 - Thanks, Stephen!) and Huseyin is a developer who recently joined the group and is already making a big impact.

Most of the time here is spent on the whiteboard with Daan. Make some time for this conversation. There's an awful lot to learn here.

Enjoy!

Burton is a parallel computing expert, an industry thought leader in high performance, massively parallel distributed (aka super) computing. Winner of the Seymour Cray Computer Engineering Award, Burton knows a thing or two about how to architect and implement software systems that can succeed in the Age of Manycore.

This is a long and great conversation, unedited of course. You'll want to make some time for this and listen carefully to what Burton says. This is a very important general introduction to parallelism and high performance computing. As always, we can't talk about super computing without addressing program language evolution in the context of manycore (you've seen this quite a bit on C9 over the years). We cover a lot of ground here including Burton's insights into functional programming, transactions, compatability, shared mutable state, operating systems, technical redunancy and the role of Technical Fellows in the post-Bill era.

Enjoy this great introduction to parallelism and the future of our platform technologies and tools as we head into the age of manycore. This is the first in a series of several interviews covering parallel computing and Microsoft's Parallel Computing Platform technologies, specifically.

PFX makes it easier for developers to write programs that take advantage of parallel hardware (you've all heard of multi-core and what the future holds with many-core...), without having to deal with the complexities of threads and locks in today’s concurrent programming story. Of course, PFX is not a concurrent programming silver bullet. There is still a great deal of work left to do in the imperative programming world's approach to concurrency. PFX is an excellent start with a syntax that .NET developers can relate to and understand.

Here, Joe Duffy, Senior Software Engineer, and Technical Fellow Anders Hejlsberg sit down with me to discuss the basics and some of the details of the managed PFX library's architecture and implementation, whiteboard included.
