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...

Today I am going to present a way to measure the performance of C++ AMP algorithms. Specifically I am going to show you how to accurately measure elapsed time, and what you need to know while placing the timer in your code. In the examples below I am...

Howdy ho! My name is Simon Wybranski, I am a developer on the C++ AMP team! In this blog post I am going to present a high-resolution timer for measuring the performance of C++ AMP algorithms. There is nothing specific in it to C++ AMP, so it can be...

Most of the code samples shared by our team have been passing lambda expressions to the parallel_for_each call. Lambdas, which have been supported in VC++ since VS2010, are a new feature in C++11, which was published just over 2 months ago. There seems...

C++ AMP offers a tiled model to help user take advantage of the fast and programmable cache on GPU hardware, which is exposed as tile_static memory in C++ AMP.  In this blog post, I will first dive into a synchronization mechanism for coordinating...

As you may know, in C++ AMP, the entry point for device code is the parallel_for_each function. What you may not know is that the compiler will inline all the function calls in the call graph rooted at the lambda/functor that is supplied to the parallel_for_each...

Hello, my name Joe Mayo and I am an engineer on the C++ AMP team. I have over a decade of experience working with C# and .NET and in the past couple years have gained experience working with C++ in the GPU space. When I joined the C++ AMP team I was pleased...

Mersenne Twister(MT) Pseudo Random Number Generator (PRNG) is one of the common PRNG. With this post I am sharing a C++ AMP implementation of Mersenne Twister based on a pseudorandom number generator algorithm developed by Makoto Matsumoto and Takuji...

Hi, I am Lingli Zhang, a developer on the C++ AMP team and this is the first in a series of posts on C++ AMP restrictions. In a previous post, we have introduced a key new language feature introduced with C++ AMP -- restrict specifiers , a new part of...

Hello, my name is Łukasz Mendakiewicz and I am an engineer on the C++ AMP team. Converting C++ data parallel algorithms to take advantage of C++ AMP is fairly straightforward, assuming you can live with some of the restrictions of restrict(amp) functions...

Need a quick introduction to C++ AMP? I have recently written a gentle introduction to C++ AMP and massive data parallelism , for the developerFusion webzine. This article joins two other introductory articles we have already published: 1. Daniel...
