  • Blog Post: C# memory model articles

    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.
  • Blog Post: New articles on async/await in MSDN Magazine

    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...
  • Blog Post: "C# 4.0 in a Nutshell" parallel programming content

    Joe Albahari, author of "C# 4.0 in a Nutshell", has just published on his Web site the material from his book covering Parallel Extensions. You can find his extensive article here: http://www.albahari.com/threading/part5.aspx Nice work, Joe.
  • Blog Post: Using Cancellation Support in .NET Framework 4

    The .NET Framework 4 introduces a new mechanism for cancellation of operations, based on new types CancellationToken and CancellationTokenSource. This cancellation mechanism is used across the parallel programming libraries: tasks, concurrent collections, and PLINQ queries. Using Cancellation Support...
  • Blog Post: PLINQ and Office Add-ins

    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...
  • Blog Post: Integrating Parallelism with Windows Workflow Foundation

    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...
  • Blog Post: Concurrency Visualizer: A Case Study

    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...
  • Blog Post: PLINQ’s Ordering Model

    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...
  • Blog Post: Performance of Concurrent Collections in .NET 4

    .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...
  • Blog Post: When To Use Parallel.ForEach and When to Use PLINQ

    If you've played around with PLINQ and Parallel.ForEach loops in .NET 4, you may have noticed that many PLINQ queries can be rewritten as parallel loops, and also many parallel loops can be rewritten as PLINQ queries. However, both parallel loops and PLINQ have distinct advantages in different situations...
  • Blog Post: A Tour of Various TPL Options

    The Task Parallel Library (TPL) exposes various options that give you more control over how tasks get scheduled and executed: Choose whether to optimize for fairness or for overheads when scheduling tasks. Specially mark tasks known to be long-running to help the scheduler execute efficiently...
  • Blog Post: Parent-Child Task Relationships in the .NET Framework 4

    The Task Parallel Library in the .NET Framework 4 provides an opt-in feature that enables parent-child relationships between tasks. This relationship brings with it some additional behaviors, including that a parent task is not considered completed until all of its child tasks have completed, and that...
