Multithreading: when interlocked operations aren’t enough - LA.NET [EN]
Multithreading: when interlocked operations aren’t enoughPublished Thu, Jul 2 2009 15:45 In the previous post, we’ve started looking at interlocked operations. As we’ve seen, interlocked operations are great at what they do but they won’t be usable in all scenarios (ie, don’t think that they’ll solve all your locks problems). To show how things might go awry when using interlocks, I’ll reuse a great example written by Raymond Chen a few years ago (I’m updating it to C... (more)

Multithreading: introducing the interlocked operations - LA.NET [EN]
Multithreading: introducing the interlocked operationsPublished Thu, Jul 2 2009 12:58 As we’ve seen in the previous post, most processors give us important insurances regarding memory loads and stores. However, even though those insurances are important and can be used in several scenarios, the truth is that they aren’t enough for all real world tasks. Fortunately, most processors also offer a group of interlocked operations which enable atomic compare and swap scena... (more)

Multithreading: hardware atomicity - LA.NET [EN]
Multithreading: hardware atomicityPublished Mon, Jun 29 2009 22:41 In the previous post, we’ve started looking at memory loads and stores reordering. In this post, we’re going to keep our study and we’re going to introduce atomicity. Atomicity is a really important concept we’ve met in the past. We’ve already talked about it on a higher level: do you recall our discussion on critical regions (and how they’re implemented through critical sections)? With critical regi... (more)

Multithreading: load and store reordering - LA.NET [EN]
Multithreading: load and store reorderingPublished Mon, Jun 29 2009 10:55 Until now, we’ve been busy talking a look at several interesting topics associated with multithreading programming. As we’ve seen, one of the most problematic areas in multithreaded programs is sharing state across multiple threads. As we’ve seen in several posts along this series, we can use a critical regions for ensuring that shared state is accessed by one thread at a time. In other words, u... (more)

Multithreading: the BackgroundWorker class - LA.NET [EN]
Multithreading: the BackgroundWorker classPublished Thu, Jun 25 2009 11:27 In the last posts of the series, we’ve been looking at many important features related to GUIs and multithreading. Today, we’re going to wrap up this topic with the BackgroundWorker class. The previous posts are really targeted at library developers. The truth is that having to implement the EAP pattern  to have asynchronous behavior is simply too much work. Interact with the SynchronizationC... (more)

Multithreading: AsyncOperationManager and AsyncOperation helpers
In the last posts, we’ve taken a look at how synchronization contexts help marshal work across threads. Today we’re going to talk about two classes (which we’ve already met in the past when we implemented the EAP) that abstract even further the use of synchronization contexts: I’m talking about the AsyncOperationManager and AsyncOperation classes. Let’s start with the AsyncOperationManager class. (more)

Multithreading: Introducing synchronization contexts - LA.NET [EN]
Multithreading: Introducing synchronization contextsPublished Tue, Jun 23 2009 11:08 In the last post, we’ve seen how to marshal back the results obtained on a secondary thread so that controls are updated on the GUI thread. Today we’re going to start looking at synchronization contexts. Synchronization contexts are abstractions for marshalling between threads. In other words, they abstract those scenarios where you cannot call a method from the current thread and nee... (more)

Multithreading: windows forms and synchronization contextsPublished Tue, Jun 23 2009 12:14 In the previous post, we’ve started looking at synchronization contexts. In this post, we’ll take a close look at the widows forms custom synchronization context. Whenever you run a windows form app, you might end up interacting with the WindowsFormsSynchronizationContext. The constructor of this class is responsible for getting a reference to the GUI thread so that it can then ... (more)

Multithreading: the ISynchronizeInvoke interface - LA.NET [EN]
Multithreading: the ISynchronizeInvoke interfacePublished Mon, Jun 22 2009 20:26 In the last post, we’ve see that multithreading is almost a necessity in GUIs. We’ve also seen that there are some gotchas associated with it: a control can only be updated from the GUI thread. In practice, this means that we’ll need to marshal back the results to the main thread when they’re ready. In .NET, the Windows Forms introduces the ISynchronizeInvoke interface for performing tha...

Multithreading: adding cancelation to the initial event based pattern implementation - LA.NET [EN]
Multithreading: adding cancelation to the initial event based pattern implementationPublished Thu, Jun 18 2009 22:45 Today we’re going to improve the code we’ve started writing yesterday: we’re adding canceling support. As you might recall, in our last post we’ve built a simple class which supports a single asynchronous operation at a time. Since we only support one asynchronous operation at a time and we can only start one asynchronous operation from our class, then ... (more)

Today, we’re going to look at how we can implement that pattern. We’re going to start small and we’re going to reuse the IAsyncResult sample for showing how you can implement this pattern. As we’ve seen in the previous post, we need to (at least) add a method (named XXXAsync) t... (more)

Multithreading: introducing the event based asynchronous patternPublished Tue, Jun 16 2009 10:06 In the last posts we’ve looked at several details associated with the use of the APM pattern. Today we’re going to start looking at the second pattern for doing asynchronous work: the event based asynchronous pattern. This pattern was introduced with .NET 2.0 and it targets components that are going to be used in GUIs. In other words, if you’re building components that ar... (more)

Multithreading: implementing the IAsyncResult interfacePublished Mon, Jun 15 2009 11:47 Today we’re going to wrap up our study of the APM pattern by seeing how we can implement the IAsyncResult interface.

Multithreading: understanding the BeginXXX and EndXXX methodsPublished Sun, Jun 14 2009 21:42 Now that we’ve looked at the available waiting options for the APM pattern, it’s time to start digging on its internals. This post is all about understanding the work of the BeginXXX and EndXXX methods (which isn’t much, as we’ll see). As we’ve seen in previous posts, the BeginXXX method is responsible for kicking off the asynchronous processing. In theory, you’d expect it t... (more)

Multithreading: the APM pattern and polling for completion - LA.NET [EN]
Multithreading: the APM pattern and polling for completionPublished Wed, Jun 10 2009 12:09 In this post we’re going to take a look at how we can use polling to see if an asynchronous task has completed. As we’ve seen, the IAsyncResult instance returned from the BeginXXX method (that started an asynchronous task) has an IsCompleted property that returns true when the task is completed. In practice, this means that you can use this property for polling the status of th... (more)

Multithreading: APM and the continuation passing stylePublished Wed, Jun 10 2009 13:35 In this post, we’ll take a look at the last option we can use for the rendezvous phase of the APM pattern. This last option is based on the continuation passing style principle. In practice, this means that we need to wrap up the work that should be performed after the async task ends in a closure and pass it to the BeginXXX method. There are some cases where this might not be a vi... (more)

In this post we’re going to see how we can use the WaitHandle which we can get through the IAsyncResult’s AsyncWaitHandle property. After getting a valid reference to it, you can do what you normally do with handles: make the thread wait until it get... (more)

Multithreading: blocking the thread by calling EndXXX directlyPublished Tue, Jun 9 2009 10:07 As we’ve seen, one of the available options is blocking the thread by calling the EndXXX method directly. This might be a good option when you only need to do one or two small tasks and then you need to wait until the asynchronous operation is completed. In practical terms, this option won’t be usable in many scenarios. However, I’d say that this is the easiest of the four a... (more)
