摘要：NVIDIA公司在1999年发布GeForce256时首先提出GPU（图形处理器）的概念，随后大量复杂的应用需求促使整个产业蓬勃发展至今。GPU在这十多年的演变过程中，我们看到GPU从最初帮助CPU分担几何吞吐量，到Shader（着色器）单元初具规模，然后出现Shader单元可编程性，到今天GPU通用计算领域蓬勃发展这一清晰轨迹。本报告首先根据搜集到的资料记录GPU通用计算的发展过程中硬件和

The debugging support introduced for C++ AMP in Visual Studio 2012 has been extended in Visual Studio 2013 when running on Windows 8.1 so that you are able to debug both the CPU and GPU parts of your

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 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 hand

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 restr

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 fas

Hi there, my name is Weirong Zhu, and I’m a developer on the C++ AMP team.  In this blog post, I will show you how to use staging arrays to optimize your data transfers between the host and a C++ AMP

Some of our existing and upcoming blog posts illustrate how to get the best performance from C++ AMP, with a focus on today’s DirectX 11 GPUs, and a focus on our v1 capabilities. This post will serve

比较一下CPU和GPU的通用计算能力，我的显卡是AMD的，没法使用CUDA……前段时间尝鲜Win8，顺便就下载了一个Visual Studio 11 Beta，发现里面有一个C++ AMP，拿来比较一下。根据目前的资料，只要显卡支持DirectX 11就可以使用 C++ AMP，就是将代码编译成x86和HLSL       比赛的方法是准备一个10000个32位浮点数，对每个浮点数做100000次

终于有时间把这篇博客给补上了，理论知识我会在另外一片数学知识中讲到。写了一个静态的方法，GPU实现的方便并不难（比起来DirectCompute里的复杂配置，amp的确提供了异常方面的接口）。具体代码见下，我会做一些讲解。static void HoughFitPlanGPU(float* pXData, float* pYData, float* pZData, int count, PlanP
