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...

One issue that consistently trips people up when they start using lambdas in asynchronous programming (particularly, using PPL), is the lifetime of the variables captured in the lambda expressions. More than once, I’ve fallen into this trap myself...

Hi there, in this blog post, I’m going to briefly introduce a new C++ AMP feature area of Visual Studio 2012. For more details, we will keep adding links to related blogs posts at the bottom of this post, so please come back often and scroll down to the...

Hello! My name is Daniel Griffing and I’m a test engineer on the C++ AMP team. C++ AMP provides a great set of capabilities that scale well for N-Rank (dimensional) data by providing data types to encapsulate the shape ( concurrency::extent ...

Hello, my name is Tamer Afify, and I’m a test engineer on the C++ AMP team.  In this blog post, I will share a change in the C++ AMP API that you will observe with the VS 11 Beta (and beyond). In the Visual Studio 11 Developer Preview, C++ AMP had...

In statistics, Histogram helps understand distribution of data or help gauge density of certain data. This is mainly used in data mining applications and image processing. In this blog post I am sharing a C++ AMP sample of a histogram implementation ported...

In C++ AMP, the type char is part of the subset of the C++ language restricted from use on accelerators . Fortunately, it’s relatively easy to work around this restriction, and you may even get better performance to boot (though this is dependent...

In this blog post, I’m going to explain how you can make use of a GPU’s constant memory with C++ AMP. I will first introduce what constant memory is and how it is accessible in C++ AMP. I will then share some implementation details and usage...

This post assumes and requires that you have read the introductory post to this series which also includes a table of content . With that out of the way let’s look at of restrictions with regards to tile_static. C++ AMP introduces a new storage...

Hello, I am Hasibur Rahman, an engineer on the C++ AMP team. As C++ AMP is meant to utilize the computing power of accelerators such as the GPU, it is natural that any application leveraging this computational power through C++ AMP will involve transferring...

This post assumes and requires that you have read the introductory post to this series which also includes a table of content . With that out of the way let’s look at restrictions on amp lambda capture rules. There are some restrictions on what...

This post assumes and requires that you have read the introductory post to this series which also includes a table of content . With that out of the way let’s look at of restrictions on amp lambda expressions. Restriction specifiers can be applied...

In a previous blog post I showed how to call a native function implemented using C++ AMP located within a native DLL from a C++ CLR application . Some out there may feel that managing two projects (a native DLL and a managed assembly) is overkill just...

Hi, I’m Steve Deitz, a developer on the C++ AMP team, and in this post, I’ll review the atomic operations available in C++ AMP, mention some important caveats, and show a simple example. Atomic operations are the only safe and correct way...

This post assumes and requires that you have read the introductory post to this series which also includes a table of content . With that out of the way let’s look at some restrictions for some statements, operators and the volatile qualifier. ...
