For some developers, reading code (that fully compiles in a Visual Studio project) is a much better way to learn an API than reading documentation about an API. If that describes you, then you'll be happy to know that in between our blog posts explaining...

Feb 2012: Published original v0.9. May 2012 : Attachment Updated to v0.99. August 2012 : Updated to v1.0. When we announced C++ AMP in June 2011, we also announced that it would be an open specification. Since then we have made multiple interim releases...

With Visual Studio 2012, you are able to get your hands on a new technology that enables you to tap into the power of heterogeneous hardware and specifically take advantage of accelerators such as the GPU for compute purposes: C++ AMP . So you'll create...

So you are a newbie to C++ AMP – you know nothing and want to quickly get started, we have you covered – keep on reading! Step 1 – Do this first! While it is typical for many to learn a new technology by writing your own "Hello World", if you...

Hello, my name is Jonathan Emmett and I’m a developer on the C++ AMP team. In this post I’ll be talking about the problems with mutable lambdas and function objects with non-const function call operators in C++ AMP kernels. There are a number...

This post will introduce and explain a new compiler feature in Visual Studio 2012, called auto-vectorization. (A previous post - what is vectorization? - provides background) The Visual Studio 2012 auto-vectorizer tries to make loops in your code run...

Microsoft has recently released a beta for Windows 7, and a look at the official web site ( http://www.microsoft.com/windows/windows-7/default.aspx ) will show you a pretty impressive list of new features and usability enhancements. I encourage you to...

My name is Bharath, I am an SDET on the C++ AMP team. I worked on the NBody demo and wanted to share this project with you. You may have seen our PM ( Daniel Moth ) demonstrate at AMD Fusion Developer Summit and at Microsoft Build Conference (for the...

Living with Latency Our customers demand more speed and responsiveness from applications. At the same time, as the applications are becoming more and more connected, we are increasingly confronted with the latency inherent in I/O devices. A thread...

In this blog post, I will share a C++ AMP implementation of a fractal generator, rendering 4 dimensional Quaternion Julia fractals . I’ll show you screenshots of the app, then we’ll dive into the code, and then I’ll share a pointer of...

If you’ve seen any of the Windows Runtime talks from //build/ (like this one), one of the things you’ll discover is that asynchronous APIs are pervasive throughout it. Operations which can potentially be long running – particularly things...

Marko Radmilac, Senior Developer for Microsoft’s Concurrency Runtime, offers the following discussion of parallel iteration in the Concurrency Runtime: Let me say up front that this is my first blog, so I apologize if my writing format does not match...

The most difficult problem that a scheduler or a thread pool has to solve is figuring out how many running threads to have at any given moment. Create too many threads and the CPUs are oversubscribed. Create too few and the CPUs are underutilized. The...

We have walked you through the C++ AMP texture feature with this series on concurrency::graphics , including how to interop with DirectX11 textures in C++ AMP . In this blog post, I will use a sample that implements some image effects to show you how...

Support for GPU debugging on Windows 7 platform has been a popular request from our customers. Now, we are pleased to announce that by installing the following platform update , you can try out GPU debugging on Windows 7 or Windows Server 2008 R2 platforms...

Hi there, in a previous blog post I talked about the data transfer APIs provided by C++ AMP . In this blog post I will be talking about some interesting scenarios involving data transfer while working with array_view . I will describe various operations...

We think of our matrix multiplication example as "Hello world", but it didn't sit quite well with me. It was missing the essential ingredients for a "Hello world" demo which are: to be simple, require a complete code listing, fit on a single slide, and...

Many of you have been wondering about availability of additional C++ AMP libraries. As part of the shipping product you already have C++ AMP which itself is a library, and also the C++ AMP Math library . But you have been asking about additional libraries...

Welcome back! Last time, we looked at how to use the auto keyword in Visual C++ 2010 to implicitly declare local variables based on their initialization (see The Concurrency Runtime and Visual C++ 2010: Automatic Type Deduction ). This week we’ll...

In this blog post I am sharing a sample named Random Traveler, which demonstrates a graph based algorithm. Using the sample The random traveler starts at an airport, takes an outgoing flight, reaches another airport, again takes an outgoing flight from...

In this blog I will be giving an introduction to the native concurrency support in Visual Studio 2010. My motivation is that an architectural understanding of the features will enable the reader to make the most of the underlying infrastructure. In future...

Hi, I am Jim Hogg, a Program Manager in the Visual C++ compiler team. This short post explains “What is vectorization?”. It provides background for an upcoming sequence of posts on a new feature within the Visual Studio 2012 C++ compiler,...

The Parallel Patterns Library (PPL) , a programming model that resembles the C++ Standard Template Library (STL), was introduced in Visual Studios 2010. PPL provides general-purpose containers and algorithms for performing fine-grained parallelism. Additional...

Some of you don't just want to learn C++ AMP, but you also want to present on C++ AMP to your colleagues, or at user groups and other such events. To help you with that goal, we have made available a set of slides from which you can pick the ones that...
