03.08.2021 · In this article. The Parallel Patterns Library (PPL) task class. A task object represents work that can be executed asynchronously and concurrently with other tasks and parallel work produced by parallel algorithms in the Concurrency Runtime. It produces a result of type _ResultType on successful completion. Tasks of type task<void> produce no result.

02.04.2014 · The Parallel Patterns Library (PPL) provides C++ developers with some very useful concurrency primitives along similar lines as Task parallelism in .NET. Having been introduced in Visual Studio 2010, the PPL is not new by any means.However, it remains relatively obscure to many who dabble in native code. Similar to .NET, task<T> is the main star of the native async …

02.11.2015 · The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design. This project aims to help C++ developers connect to and interact with services. - Programming with Tasks · microsoft/cpprestsdk Wiki

Так как С++ 11 не имеет future.then , я начал использовать concurrency::task из библиотеки Microsoft PPL , Он отлично работает большую часть времени.

03.08.2021 · In this article. In the Concurrency Runtime, a task is a unit of work that performs a specific job and typically runs in parallel with other tasks. A task can be decomposed into additional, more fine-grained tasks that are organized into a task group.. You use tasks when you write asynchronous code and want some operation to occur after the asynchronous operation …

02.08.2018 · Creating an awaitable lock for C++ PPL tasks. Raymond. August 2nd, 2018. The C# language (well, more accurately, the BCL) has the Reader­Writer­Lock­Slim class which has a Wait­Async method which returns a task that completes asynchronously when the …

Is there any standard way to pre-initialize the PPL thread pool? ... I'm having fun with c++-ideas, and got a little stuck with this problem.

14.08.2012 · If you are doing C++ programming in Windows 8 and don’t know about the PPL tasks and how they make asynchronous programming much easier, then this post is the wrong starting point for you.. Callbacks and PPL…What’s the Problem? What is great about the PPL tasks is being able to chain tasks using the .then(…).

How does when_any work? windows-8 c++-cx ppl. I have a std::vector< concurrency::task<void> > ...

03.08.2021 · The PPL provides a programming model that resembles the C++ Standard Library. The following example demonstrates many features of the PPL. It computes several Fibonacci numbers serially and in parallel. Both computations act on a std::array object. The example also prints to the console the time that is required to perform both computations.

concurrencpp is a task-centric library. A task is an asynchronous operation. Tasks offer a higher level of abstraction for concurrent code than ...

23.05.2013 · I'm still learning PPL myself, but one thing I've learned that's held up so far is that you should pretty much always be doing something with any task you create. The usual thing to do is use then to turn it into a new/different task, but you still need to do something with the task returned by the last then .

The basic code is very similar to the C++11 example in part 2 and looks ... Comparison between PPL task groups, C++ thread library and a ...

14.12.2016 · The PPL support was only meant to help one of our internal customers who could not immediately upgrade to the C++ compiler that supports coroutines. While Visual C++ will continue to support PPL for some time, we do not encourage its use for new code and will likely remove the PPL header from a future update of C++/WinRT.

We saw that the library, introduced with C++11, offers a partial ... of the platform-specific improvements offered by Microsoft's PPL tasks, ...

18.10.2012 · We use a PPL Concurrency::TaskScheduler to dispatch events from our media pipeline to subscribed clients (typically a GUI app). These events are C++ lambdas passed to Concurrency::TaskScheduler::
