Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. The prototype with a full text and hyperlink database of at least 24 million pages is available at http: Search engines index tens to hundreds of millions of web pages involving a comparable number of distinct terms. They answer tens of millions of queries every day.
History[ edit ] General-purpose computing on GPUs only became practical and popular after aboutwith the advent of both programmable shaders and floating point support on graphics processors. The scientific computing community's experiments with the new hardware began with a matrix multiplication routine ; one of the first common scientific programs to run faster on GPUs than CPUs was an implementation of LU factorization The second one, being hosted by Khronos Group on GitHub, and possible to be compiled for any modern operating system.
It provides a simplified programming model, automates parallelisation, manages devices and memory, and compiles to CUDA binaries. Additionally, multi-core CPUs and other accelerators can be targeted from the same source code. It supports generics and virtual functions. NET language F  and C.
Mobile computers[ edit ] Due to a trend of increasing power of mobile GPUs, general-purpose programming became available also on the mobile devices running major mobile operating systems. Cards from such vendors differ on implementing data-format support, such as integer and floating-point formats bit and bit.
Microsoft introduced a Shader Model standard, to help rank the various features of graphic cards into a simple Shader Model version number 1. Integer numbers[ edit ] Pre-DirectX 9 video cards only supported paletted or integer color types. Various formats are available, each containing a red element, a green element, and a blue element.
Sometimes three bits for red, three bits for green, and two bits for blue. Floating-point numbers[ edit ] For early fixed-function or limited programmability graphics i. It is important to note that this representation does have certain limitations.
Given sufficient graphics processing power even graphics programmers would like to use better formats, such as floating point data formats, to obtain effects such as high dynamic range imaging.
DirectX 9 Shader Model 2. Full precision support could either be FP32 or FP24 floating point or bit per component or greater, while partial precision was FP ATI's Shader Model 3. Although not stipulated by Shader Model 3.
While bit floating point values double precision float are commonly available on CPUs, these are not universally supported on GPUs. Efforts have occurred to emulate double-precision floating point values on GPUs; however, the speed tradeoff negates any benefit to offloading the computing onto the GPU in the first place.

Many other applications can put this to good use, and because of their higher performance, vector instructions, termed single instruction, multiple data SIMDhave long been available on CPUs.
