Stephen Toub - MSFT
Igor Ostrovsky is one of the minds behind the parallel programming support in the .NET Framework.  Igor's recently written a great set of articles for MSDN Magazine to cover "The C# Memory Model in Theory and Practice".  Part 1 is available now in the December 2012 issue, and it's a great read...

New articles on async/await in MSDN Magazine

October 3, 2011 Oct 3, 2011 10/3/11
Stephen Toub - MSFT
The October 2011 issue of MSDN Magazine is now available online.  In it, you can find three articles about the new async/await features of C# and Visual Basic.  While the articles can stand alone, they were written with each other in mind in order to provide a 1-2-3 on-ramp into the world of asynchronous programming with these new ...

PLINQ and Office Add-ins

Igor Ostrovsky - MSFT
Many different kinds of applications can benefit from multi-core parallelism, including add-ins to Microsoft Office. Donny Amalo wrote a paper, PLINQ and Office Add-ins, where he demonstrates how to implement two parallel Microsoft Office add-ins using PLINQ: A parallel Monte Carlo simulation add-in for Excel A parallel custom ...

Integrating Parallelism with Windows Workflow Foundation

June 28, 2010 Jun 28, 2010 06/28/10
Igor Ostrovsky - MSFT
Despite the similarity in naming, the System.Threading.Tasks.Parallel class and the System.Activities.Statements.Parallel* activities in WF4 are largely orthogonal in the scenarios they address. However, WF4 activities and the new parallel programming types in .NET 4 can be used together to great advantage.Ling Wo and Cristina Manu wrote ...

Igor Ostrovsky - MSFT
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 ...

PLINQ’s Ordering Model

June 21, 2010 Jun 21, 2010 06/21/10
Igor Ostrovsky - MSFT
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...

Performance of Concurrent Collections in .NET 4

April 26, 2010 Apr 26, 2010 04/26/10
Igor Ostrovsky - MSFT
.NET 4 introduces new data structures designed to simplify thread-safe access to shared data, and to increase the performance and scalability of multi-threaded applications. To best take advantage of these data structures, it helps to understand their performance characteristics in different scenarios.Chunyan Song, Emad Omara and Mike Liddell ...
