CCR at MySpace

Michael S. Scherotter — Tue, 06 Oct 2009 15:22:00 GMT

MySpace has done some pretty amazing things with the Robotic Developer Studio. When they found out it contained a very powerful component, the Concurrency and Coordination Runtime (CCR), the architects built it into the architecture of MySpace, the largest .NET site in the world. At MySpace, I met Principal Architect Erik Nelson and Senior Architect Akash Patel who walked me through how they were using the CCR.
If you have an MSDN subscription, you are a student, or you are at a qualifying startup, you can now download and use the Robotic Toolkit as part of the program.

Talking about Microsoft Robotics and VPL with Trevor Taylor

John O'Donnell — Fri, 22 May 2009 22:19:00 GMT

During my last visit to the Microsoft Redmond Campus Trevor Taylor from the Microsoft Robotics team was kind enough to talk to me about the Microsoft Robotics platform and in particular Visual Programming Language or VPL. Of course when you talk aout robotics there is always an opportunity to talk about other cool technology such as the simulation environment and the great things our partner http://www.simplysim.net are doing with it.

If this video peaks your interest in Microsoft Robotics then take a look at the book Trevor co-authored with Kyle Johns

Expert to Expert: Meijer and Chrysanthakopoulos - Concurrency, Coordination and the CCR

Charles — Fri, 16 Jan 2009 20:56:00 GMT

In this episode of Expert to Expert, programming language designer Erik Meijer chats with CCR creator George Chrysanthakopoulos. We've spent a good deal of time on Channel 9 addressing the Concurrency Problem and the various approaches Microsoft is taking in an effort to help solve it. George's CCR is a piece of managed technology (.NET) that provides an unusually high degree of concurrency for developers targeting Windows. The Coordination and Concurrency Runtime has been around for about five years. How are people using it today to build scalable concurrent systems? What's the current state of the CCR and what's it's future? Why is the CCR a better approach to scalable distributed concurrent programming than other technologies out there? Is concurrency the real issue? George believes that it's all about coordination(the other C in CCR) and concurrency is really just a side effect of coordinating systems. If you get distributed coordination right, then you have a concurrent system that can scale. Really? Do explain, dear George (oh, and he does and as passionately as you'd expect from him). This is a fantastic conversation. Classic Channel 9.

Enjoy!

Jeffrey Richter and his AsyncEnumerator

Charles — Thu, 04 Dec 2008 01:52:00 GMT

Jeffrey Richter’s Power Threading Library contains his AsyncEnumerator class which uses C# iterators to allow developers to perform asynchronous operations via an easy to use synchronous programming model. For those of you who can remember our conversations on CCR from years back, the use of iterators in this concurrent context is at the core of CCR's implementation of asynchronous processing. The power of iterators in C# enables all of this. The CCR team was in fact the first to employ an asynchronous programming model based on C# iterators, which was a very novel use of the new feature in C# 2.0. This doesn't take away from Jeff's current excellent async implemenation (not at all - Jeff has made some real innovation here!).

Watch this Screencast produced by Developer Division Community Program Manager Charlie Calvert to learn how Jeff's library enables the creation of scalable and responsive applications with minimal resources (threads/context switches). The library discussed in this Screencast can be downloaded from http://wintellect.com/PowerThreading.aspx.

George Chrysanthakopoulos: Microsoft CCR and DSS Toolkit 2008

Charles — Wed, 29 Oct 2008 20:37:00 GMT

The great George Chrysanthakopoulos (CCR creator) chats with us briefly about the new CCR and DSS Visual Toolkit. You first learned about CCR right here on Channel 9. Since that time it's had a very interesting evolution. The CCR found itslef at the core of the Microsoft Robotics engine on the one hand and running in the cloud on 50,000 servers processing billions of transactions. George and team have always been impressed with how people have used the CCR (many folks have downloaded the Microsoft Robotics SDK for the express purpose of getting at the CCR). Well, now you gaet the stand-alone CCR plus DSS in a neat application development package including Visual Programming Language.

ARCast.TV - Stephen Tarmey of Tyco on adopting Robotics Studio CCR for High Performance Async IO

Bob Familiar — Tue, 16 Sep 2008 15:19:00 GMT

Bob Familiar interviews Stephen Tarmey of Tyco Software House on how he discovered the Concurrency and Coordination Runtime in the Robotics Studio SDK and used it to implement a high throughput asynchronous I/O pattern.

Microsoft Robotics Tour: CCR, VPL, Simulation - Part 1

Charles — Mon, 23 Apr 2007 19:31:53 GMT

We recently went back to visit the Microsoft Robotics team to see what they're up to. As expected, they are very busy innovating! This is a four part series where we learn about what's new in CCR (and watch George code!), get a demo of the Visual Programming Language's debugger (outrageously cool stuff), get a demo of the robotics simulation environement and get a status report from team lead Tandy Trower.

Here, George takes us through what we'll be seeing in this tour and gives us an update on the CCR and how it's being used in the real world.

Enjoy!

CCR Programming - Jeffrey Richter and George Chrysanthakopoulos

Charles — Mon, 24 Jul 2006 18:37:41 GMT

Do you remember our introduction to the Concurrency and Coordination Runtime (Microsoft Robotics Studio)? Well, now we dive into the CCR API itself and learn how to use it.

If you're a developer ustilizing Microsoft platform technologies, you've probably heard of Wintellect's Jeffrey Richter. He's worked on everything from Windows to the CLR.

CCR creator George Chrysanthakopoulos commisioned Jeffrey to help make the CCR API both more approachable as well as more consitent with BCL's syntactic conventions.

Here, George Chrysanthakopoulos, Charles and Jeffrey Richter dive into demos of the CCR API as well as discuss the What How and Why of it.

At the end of the interview, you'll see an excellent real world example of how to use the CCR... (Not going to give it away. You need to watch the whole video :))

Please check out Jeffrey's latest installment of Concurrent Affairs to learn more about the new, improved CCR API and get a hold of sample code to play with. Also, see CCR Wiki. This is super cool stuff and represents a really innovative approach to making managed threaded programming more readily understandable and predictable.

Please check out the OOPSLA/SCOOL paper on the CCR.
