APP is the abbreviation of Accelerated Parallel Processing.Chinese translation AMD accelerationParallel processing technology。AMD aims toGraphics Processor(GPU).This technology can give full play to the parallel computing ability of AMD GPU, which can be used to accelerate the software or conduct large-scale scientific operations.

APP
Role
Give play to the parallel computing ability of AMD GPU
AMDThe predecessor of APP technology is calledATI Stream。In October 2010, with the release of AMD Radeon HD6800 series graphics cards,ATIThe brand was officiallyAMDreplace.ATI Stream technology has also been upgraded and renamed AMD APP technology.AMD APP's competitor is NVIDIACUDA。
About AMD APP AccelerationParallel processing technologyFor more information, please refer toAMD APPEntries.APP is both a generation technology and an application that can be generated automatically in real time. Users only need to do some analysis and description, and then arrange the graphical interface to complete the design of APP, dear programmers.[1]

AMD graphics cardThe ATI Video Converter included in the driver is a video transcoding software based on APP technology. ATI Video Converter is not a software completely based on GPU transcoding, butCPU+GPUuniontranscoding 。It enablesAMDGPU andCPUAccelerate together to complete the video compression only involving CPU in the past, greatly reducing the compression time.Compared with Badaboom video compression software that supports NVIDIA CUDA technology, ATI Video Converter has better conversion efficiency and supports more formats. The most important thing is that ATI Video Converter is free, while Badaboom is charged.In terms of video conversion speed, ATI Video Converter is indeed faster than Badaboum.Convert the same video, and HD 4870 computer adoptsAVIVOIt only takes 48 seconds to complete the conversion, while it takes 114 seconds for GTX 280 to adopt Badaboom.Of course, speed is not the only standard. Quality is more important. At present, the compression quality of ATI Video Converter is not as good as that of Badaboum, which still needs to be improved.However, it should be noted that ATI Video Converter does not call the stream processor in the graphics card for transcoding, but calls the UVD engine for video transcoding.So different gradesATI graphics cardThe ability is the same when using ATI Video Converter transcoding.Badaboom calls the CUDA unit (stream processor) of the NVIDIA graphics card to participate in transcoding,CUDAThe video card with more units will transcode faster.In addition to the ATI Video Converter, CyberLink's Powerful Director series software, Glamour series software and ArcSoft TotalMedia's Theater software all support AMD APP technology.

NVIDIAVery successful integration of PhysXPhysical EngineThrough the combination of CUDA technology and Geforce graphics card, the nVIDIA PhysX physical acceleration technology was born.In order to compete with it, AMD launched the "Open Physics Plan" based on AMD APP technology to compete with it.The Open Physics Program combines three physics engines, namely Havok, Bullet and Pixelux DMM, and uses the powerful parallel computing capabilities of AMD GPU in games to accelerate physical computing based on OpenCL standards and AMD APP technology.At the same time, the open physics plan also implements the Fusion concept. The CPU+GPU jointly perform physical calculation, and GPU is responsible for flexibilityMaterial simulation、Fluid simulation、Explosion simulationEquicomputationallyphysical simulationcalculation.The Open Physics Program has no game support yet, but new DEMOs have been displayed on various occasions.

Folding@HomeATIIn cooperation with Stanford UniversityFolding@HomeIn the research project, ATI Radeon X1900 is used for computing acceleration.This is the first time that GPU is used for scientific research and calculation.After AMD acquired ATI, the two sides continued to cooperate.So far, countless AMD GPUs around the world are folding proteins based on AMD APP technology to help scientists conquer human diseases.At the same time, AMD APP technology has many applications in oil exploration, seismic research, etc.The Chinese supercomputer "Tianhe-1" used 2560 4870x2 graphics cards in parallelComputing Processor, which is also based on AMD APP.Brown Deer Technology is a company that surveys oil and gas through ground motion waves.After using AMD APP technology, the company found that its real-time calculation of ground motion wave is more than 120 times faster than using CPU.Similarly, the graduate students of the Chinese Academy of Sciences who won the second place at the annual meeting of China High Performance Computing used AMD APP technology in HD4870 graphics cardWhen the number of iterations reaches more than 3000, the efficiency of the medium to large scale matrix is at least 27 times higher than that of the CPU.4. Other applications, such as Excel 2010, PowerPoint 2010, Internet Explorer 9, Adobe Flash 10.1, have added support for AMD APP technology.[2]

App is short for Application in English. Due to the popularity of iPhone smart phones, the current APP mostly refers to theThird party applications。At present, the more famous app stores are Apple's App Store in iTunes, Android's Google Play Store, Nokia's ovi store, and Blackberry users' App Store,BlackBerry App World.
Apple's iOS system, app formats include ipa, pxl, deb, Google's Android system, app format is APK, Nokia's S60 system, and app formats include sis, sisx.
At the beginning, APP only participated in Internet business activities as a form of cooperation with third-party applications. With the Internet becoming more and more open,APP, as a profit model that sprouts from the iPhone, has begun to be valued by more Internet business tycoons. For example, Tencent's microblog development platform and Baidu's Baidu application platform are concrete expressions of APP ideas. On the one hand, they can accumulate various types of online audiences, and on the other hand, they can obtain traffic through the APP platform, including mass traffic and targeted traffic.
