He's passionate about solving hard problems - like writing scalable concurrent software systems. His session at YOW! - Tackling the Folklore Surrounding High Performance Computing - was excellent. You'll be able to see it online in the near future, so look for it on the YOW! site.

Martin is a Java and C++ developer and employs an analog design methodology to his digital development efforts. He thinks through the conceptual design and paints a detailed picture of the solution, then he writes code. Many developers do this, of course, but sometimes we don't think through the problem thoroughly enough before we start writing code. This is especially true when it comes to solving hard problems of a concurrent computing nature.

To Martin, the concurrency problem is as much a developer methodology, educational and behavioral problem as it is a pure technological one. We talk about this, of course. His perspectives on the subject are refreshing.

Tune in. Enjoy. Learn.

Thanks for joining us on C9, Martin. Keep pushing the envelope.

The YOW! Developer Conference offers outstanding opportunities to learn more about the latest practices, technologies, and methodologies for building innovative software solutions as well as the chance to meet and network with international software experts and other talented developers in Australia. Thanks to Dave Thomas and the event's excellent staff - Mary Catherine (MC), Lisa, Aino, Melissa, and others - for inviting me to this excellent pure developer event and thanks to all of the speakers for letting me take some of their time to record conversations for Channel 9. If you live in Australia, or aren't too far away, or just like to travel (who doesn't?), then you need to go to this yearly event. It's outstanding. There are many great developers down under. That's for sure. The speakers are exceptional—Dave and team set a high bar!

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...).

We also highlight our efforts to provide software and services to academics across the world, through the release of Dryad and DryadLINQ free of charge to the research community, along with associated programming guides, user documentation, and code libraries. Dryad is a general-purpose distributed computing engine, more flexible than MapReduce or Hadoop!, that was designed to simplify the task of implementing distributed applications on clusters of Windows computers. DryadLINQ is an abstraction layer which simplifies the process of implementing Dryad-based applications.

In this three part series, see how you can use new features in .NET Framework 4 to take advantage of multi-core processors.

  • In Part 1 of the series, we show why you care about multiple processors and how it can effect the performance in your application.
  • In Part 2 we compare the new Tasks feature in .NET with Threads.
  • In Part 3 we show three ways of using the parallel features to enable your application for multi-core processors.

In Part 1 of the series, we show why you care about multiple processors and how it can effect the performance in your application. In Part 2 we compare the new features in .NET with Threads. In Part 3 we show three ways of using the parallel features to enable your application for multi-core processors.

This is where most of the speed improvements moving forward will come from on our computers. To take full advantage of this however it is necessary to design your applications using Parallel Programming practices, also known as "parallelism".

In today’s episode, we will meet with Stephen Toub, who will share with us some of the overarching concepts associated with parallelism, and some of the ways we are trying to empower developers to develop applications to take advantage of it.

Microsoft and its rich partner’s ecosystem provide solutions to meet the challenges of parallel development and to accelerate the speed and flexibility of Microsoft Windows applications with Microsoft Visual Studio 2008.  Learn how to harness the power of Multicore, using your current Visual Studio programming experience with Visual Studio and Allinea DDTLite running on Windows HPC Server.

 

Until now, programmers could not both develop and debug parallel code, either using Threads or MPI (Message Passing Interface) and MPI.NET without having to change tools.  Learn about how Microsoft protects and enhances your existing development tools and skills; and how Microsoft Visual Studio 2008, combined with Allinea DDTLite allows you to migrate to your Windows applications to threaded and MPI without disruption. 

 

Allinea DDTLite offers truly parallel debugging for Visual Studio 2008.  DDTLite is a Visual Studio plug-in that provides easy, intuitive parallel control in an unobtrusive, integrated way to bring true parallel programming to Visual Studio 2008.  With DDTLite, programmers can still use the familiar Visual Studio 2008 features and increase parallel productivity.  Running on Windows HPC Server 2008, Microsoft Visual Studio 2008 and Allinea DDTLite  provide the optimal development environment and tools to help ease the transition to, and reduce the cost of parallel development.   Join us to learn areas to target and how to get started!
