As per the official announcement , you can now download Visual Studio 11 Beta . This version includes a "go-live" license , which means you can start using it in production environments in a supported manner. Interested in C++ AMP? Please read our...

With the release of Visual Studio 11 Beta, you get among other things an updated version of C++ AMP . After the Beta, we aspire to have no breaking changes (or even major additions) in C++ AMP, so that when you receive the final RTM release your upgrade...

In this post I’d like to explain the accelerator_view::create_marker function. It is one of those APIs that is not necessary for every program, but may be useful in some specific scenarios. Some implementation background In the current version...

We have been sharing a lot of content about C++ AMP on this blog and obviously we are excited about the technology that we created - no surprise there. I always believed, and still do, that our enthusiasm about this technology will be matched by customers...

In this product cycle release, our goal was to focus on providing comprehensive expressions for parallel patterns in C++. This Beta release allows you to start taking advantage of the libraries and go-live with your products using these features. ...

This is the third and last post in the series about the tiled extent divisibility requirement . The first post presented the requirement, the second post showed how to deal with the requirement using tiled_extent::pad , and this post will show how to...

In my previous post about the tiled_extent divisibility requirement I mentioned that you could satisfy the requirement by padding the tiled_extent , and also modify your code to account for the extraneous threads. I’ll now describe this technique...

In this post I’ll discuss a requirement of C++ AMP’s tiled model , while subsequent posts will demonstrate how to deal with the requirement in various ways. The restriction is this: The extent of a tiled parallel_for_each computation...

Dear reader You have been following the Native Concurrency blog , hopefully by subscribing to our RSS feed . If you were wondering what the C++ AMP team members look like, check out the 4 recorded interviews below where most of our team got in front...

Matrix transpose is a common operation on matrix. Here is the sample implemented using C++ AMP . main – Entry point In main, we call a driver function for each implementations of matrix transpose. test_transpose_func This is the driver...

As you know by now, as a rule most functionality in C++ AMP is in the concurrency namespace. The exception to that is the C++ AMP math library which introduces two sub namespaces ( precise_math and fast_math ), and the textures and short vector types...

This blog post assumes you have read the introduction to C++ AMP exceptions . An instance of the accelerator_view_removed exception type is thrown to handle a Timeout Detection and Recovery ( TDR ) event while executing an operation on an accelerator...

In the Visual Studio Developer Preview release of C++ AMP several core classes (e.g., extent, array, array_view) exposed members named x , y and z and get_x() , get_y() and get_z() . All such fields/properties/member functions have been removed in the...

This blog post assumes you have read the introduction to C++ AMP exceptions . An instance of the out_of_memory exception type is thrown when an underlying OS/DirectX API call fails due to failure to allocate system or device memory. Operations like...

This blog post assumes you have read the introduction to C++ AMP exceptions . An instance of the unsupported_feature exception type is thrown on invoking a parallel_for_each/ allocating an object on an accelerator which doesn’t support certain...

There is full Visual Studio debugging support for C++ AMP, and we will cover that in future blog posts . In this post, I am going to introduce three debug diagnostic functions that can be used in restrict(amp) code including a variant of the well-known...

Hello, my name is Pooja Nagpal. I am an engineer on the C++ AMP team. In this post, I would like to talk about how data is passed into a parallel_for_each for use on the accelerator. The simplest method of passing in data is by using lambdas in the...

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...

In this post, I’ll describe how C++ AMP projections can be used to write clear code that is easy to read and easy to maintain. Projections are a special case of C++ AMP sections that involve a rank change. They apply to both array and array_view...

In my, admittedly long, introduction of array_view I mentioned how by constructing an array_view with a const value type (e.g. array_view<const int,2> av ) you could achieve perf gains by letting the compiler know that you will not make changes...

In this blog post I will give a simple example of using the section member function for array and array_view , demonstrating how to offset your origin point in order to operate on a smaller section of data in your computation. So for example if your data...

This blog post assumes you have read the introduction to C++ AMP exceptions . An instance of the invalid_compute_domain exception type is thrown when the runtime fails to execute the AMP kernel for the compute domain specified at a parallel_for_each...

This blog post assumes that you are familiar with array and array_view , two types provided by C++ AMP for handling and manipulating data. Many times depending on the problem you are working with, you may want to offset your origin point and operate on...

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...
