there is still a need to reflect on this, but even if the results still recognize the current path, I still need to wonder whether I have correctly understood myself and my abilities, what are the most appropriate aspects of performance? Are there some specific forms of their performance available on the current path? How can we find opportunities to give play to them? In addition, will the simplification of life and work actually damage the integrity of internal capabilities, weaken itself as
GPU's parallel computing capability is higher than the CPU, so recently there are also a lot of projects using GPU appear in our field of view, on InfoQ saw this article about Accelerator-V2, it is a research project of Microsoft Research Institute. It needs to be registered before it can be downloaded. I feel that it is a good first step in accessing general GPU computing, So I downloaded it back.

Preface:
Before getting started, I knew almost nothing about python or tensorflow, so I took a lot of detours When configuring this environment, it took a whole week to complete the environment... However, the most annoying thing is that it is difficult to set up the environment. Because my laptop is low in configuration, the program provided by

Three-dimensional spatial analysis based on GPU accelerationTags: supermap geographic information System GisitArticle: SyedWith the rapid development and popularization of three-dimensional GIS, three-dimensional spatial analysis technology has become the hotspot of GIS technology in the application of its practicability. In the face of the increasingly large-scale data processing situation, in order to meet the practical needs of GIS industry for thr

Preface
How to optimize existing programs in parallel is the most important practical issue in GPU parallel programming technology. This article provides several optimization ideas to point out the path for parallel program optimization.
Preparation before optimization
First, we need to clarify the goal of Optimization-is it necessary to speed up the program twice? Or 10 times? 100 times? Maybe you will not think about it. Of course, the higher the im

GPU: Graphic Processing Unit (graphics processor)
OpenGL: Open Graphic Library defines the specification of a cross-programming language and cross-platform programming interface. Different vendors have different implementation methods. It is mainly used for 3D image (two-dimensional) painting.

The following is a chrome user's usage tips, hoping to help readers.
Here we will introduce the methods for enabling hardware acceleration and pre-rendering:
Go to about: flags in the chrome address bar and pull down the page to find GPU accelerated compositing and GPU accelerated canvas 2D. enable these two items. Chrome 11 does not have the GPU accelerated c

Some time ago, I wrote a series of post-process effect, including the motion blur, refraction, and scattering of screen spance. Most shader is very simple. It is nothing more than rendering a full screen quad to the screen. Generally, there are no more than 10 lines of PS Code, without any branch or loop commands. It can be run only after sm1.
Entertainment, mobile phone-hosted graphics operations are growing. Especially for the glory of the mobile phone brand for young people, users of large online games, AR/VR and other functions of the smoothness, clarity requirements are rising, but also hope that mobile phone prices as close as possible to the people. The scary technique is to honor the secret law of balance between the two needs.It's a scary technology. The "scientific name", called the GPU
Sometimes it is necessary to do coding work through Remote Desktop Connection, such as the general web, such as the need for the GPU and other support coding work directly with Windows Remote Desktop Connection coding and then debug, and some need to rely on graphics support work such as rendering, When GPU operations such as CUDA, Remote Desktop Connection debug will fail. Because when using Remote Desktop
implementation of 2-D FFT algorithm--base 2 fast two-dimensional Fourier transform based on GPU
The first one-dimensional FFT of the GPU implementation (FFT algorithm implementation-based on the GPU base 2 fast Fourier transform), and then I need to do a second-dimensional FFT, probably the following ideas.
The first thing to look at is definitely the formula:

color passed from the vertex coloring, but the brightness of the color is changed to half of the original. From the result, the effect is the same as that of the first program.Last thought
This article uses two examples to quickly introduce two different FBO extensions.
In the first example, you can use the same FBO for rendering and output to multiple textures, so that we do not need to switch between multiple fbrs frequently, the technology demonstrated in this example is very useful, because

In the past six months, it may be a decision and a decision. Maybe I have a strong sense of crisis and have always felt that I have not done well enough. I still need to accumulate and learn. Maybe it's awesome to know that you can go to Hong Kong from the Hill Valley. Step by step, you are satisfied, but you ha

Of course, arb_vertex_program extension must be supported.I am so excited that I have studied it for N days. I hope this article will help beginners.Opengl1.4 supports vertex Program (called vertex in dx) in the
