This blog post assumes you have read the introduction to C++ AMP exceptions . The runtime_exception is the base class of the all other C++ AMP exceptions. Hence this exception can be treated as the exception to be caught by default. The table below...

Visual C++ developers in need of math functions know to go <cmath> . In this blog post I’ll describe the equivalent in C++ AMP. <amp_math.h> With C++ AMP, if you want to use a math function in your restrict(amp) functions, you need to bring...

C++ AMP supports various data types for usage in the restrict(amp) functions that you schedule on the accelerator. One of those types is double . There are caveats and extra information that you need to know with regards to double precision and this post...

We announced C++ AMP in June 2011, shared the first bits in September 2011 as part of Visual Studio 11 Developer Preview, and you'll get fresh bits in the upcoming Visual Studio 11 Beta. Start with any of the links on the right to learn more about how...

I have blogged previously about the accelerator and accelerator_view classes in C++ AMP and in this post I want to focus on some specific aspects of its usage. The notion of default You can write a lot of useful C++ AMP code without ever needing...

When you author restrict (amp) kernels (the lambda you pass to parallel_for_each ), as with any other code, there are various things that can go wrong. In restrict (amp) code there is no exception handling , but the C++ AMP runtime can throw exceptions...

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 coming in the next drop of Visual Studio 11. In short, a new namespace - concurrency::graphics - is introduced to help you author data parallel algorithms...

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. ...

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 with pointer operations and casting. Since pointers in C++ AMP...

In my previous blog post on D3D interoperability with C++ AMP we looked at the APIs. In this blog post I will show a sample that uses those APIs The attached zipped file , contains a Visual Studio 11 project of DirectX 3D sample which displays the...

Hi, I am Charles Fu, a developer on the C++ AMP team. In this blog post, I will describe the C++ AMP Direct3D interoperability APIs. In my next blog post I will demonstrate how to build a simple DirectX 3D application, which renders the rotation animation...

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 around identifier expressions. In an amp-restricted function,...
