Asynchronous APIs are pervasive in the "Windows 8" Windows Runtime (WinRT). Potentially long-running operations—like file and network I/O—are typically exposed through some asynchronous pattern.

Here, we meet software engineer and ConCRT/PPL team member Genevieve Fernandes and ConCRT/PPL team member Rahul Patil (lead program manager—you've met him before). The goal here is to explain how this stuff works and why it's designed the way it is. This conversation includes whiteboarding and a code demo. You'll see how you can use C++/CX plus PPL Tasks to produce asynchronous operations that JavaScript or C#/VB can consume in very natural ways (from their perspectives) on "Windows 8." Watch and learn! 

Get the latest PPL to experiment with writing asynchronous code for "Windows 8" Metro style applications. Don't forget to provide feedback to the PPL team! They want to hear from you, so please write some code and see if you find this comfortable/useful/etc.

See the BUILD sessions on WinRT to get more information about asynchrony in "Windows 8."

Thank you Rick! This tutorial/example is done in C++, but the concepts span languages (actor-based, data flow style of programming)

Here, Rick explores converting a simple loop to a set of actors or agents that communicate via message passing.  In particular he looks at the difference between a "control flow" style implementation and a "data flow" style implementation. The actor based approach is great because it separates the guts of the work from the loop logic so code looks more like the flow charts we draw on our whiteboards.

But, there's some down sides with the control flow approach and implementing the data flow approach can be tricky.  So Rick wanted to walk through an example of both to help illustrate the differences.

The downside to the control flow approach comes in when you have lots of agents, there tends to be either a 1:1 coupling of threads to tasks OR the tasks start taking on more than one responsibility and become less manageable.

A data flow style approach helps with this, because it decouples the 1:1 thread to task relationship but it can be an awkward refactoring if you're not used to it, it takes more code, and there aren't many examples available to look at on the web so Rick wanted to share another one.

This time we subject native (C++) developer Rick Molloy to Erik's friendly interrogation. You've met Rick before (here, here, here, and here).

As usual, this Erik-led conversation involves several forays into technical areas and we jump head first into a few rabbit holes (like managed "versus" native (versus in quotes to emphasize that it's not some sort of duel...). Erik is a managed guy, after all). Lots of great geeky goodness here. So, Erik sends Rick to the whiteboard and Rick teaches Erik some modern C++ and provides some insights into his coding behavior/patterns (which is a key part of Checking In, remember?). We also sort of learn about what Rick's up to these days (secrets, secrets...).

Tune in. Enjoy. Thanks for spending time with us, Rick!

In this conversation, Mike Chu , Dana Groff, Artur Laksberg, and Vinod Koduvayoor Subramanian talk about their latest addition to the Parallel Patterns Library which provides wait-free concurrency programming by specifying tasks, the ability to schedule tasks on events and continuations that specify a task or tasks which are run after one or more tasks finish.  What’s better is that much of this is available now through the ConcRT Extra’s “Sample Pack”.

Here, Vinod Koduvayoor Subramanian, a software engineer who pushes this stuff to the limit and is a champion of target customers (also known as software testing), explains chaining tasks, continuations at the whiteboard.

It’s flexible as it does not wait for us to change the code based on hardware power. If you are deploying your application to single core this approach will mostly work. Here I have covered few things,

.  The new “Task” API
.  Parallel LINQ (PLINQ)
.  Parallel.ForEach
