With the super computer that GPU compose builds, hopeful enters the whole world before 10 of pop chart of high-powered computer TOP500
Let the world that can computer see we see? Easy as my eyes. Take camera to pat piece of photograph to be passed in computer, the computer that perhaps lets you deserves to go up photograph like the head. Want to let computer can understand his after all what to see nevertheless, that is not the hand arrives catch the thing that come.
A few days ago, a flock of coming from Ha Fo and Masschusetts Institute of Technology (MIT) forms research group jointly, planning to emulate the function of cerebrum with computer. They hope to be able to pass through operation, the video transition that sees computer becomes useful information, make computer OK then the person of differentiate content, knowledge, meaning that understands a chain of movement place to represent even. Spoken parts in an opera, stand by to person head further. moto gp xbox
GPU differentiates into emulation cerebra vision core
To accelerate research rate, the filtration that researcher uses molecular biology technology -- , choose to going up to be awaited 1000 kinds at the same time for example differentiate module has a chain of test, wash out inapplicable module, final reservation issues the most marvellous module.
This procedure is simple for it is 8 words that Darwin and Meng Deer summary come out, "Pick of content contest season, survival of the fittest " .
Come from the feedback that studies a group to show nevertheless, appear at present another difficult problem is person head the rate of analytic information is real too fast, if want to achieve this one result with conventional computer, must spend first on a large sum of money. And computer wants a flower to go up at least all the year round time ability operation completes.
What what I hope is, more or less does the method that solves difficult problem have some of score a lucky hit. The G PU that uses as game has stronger and stronger operation capacity and obtain solve, nowadays, masschusetts Institute of Technology and the researcher of haing Buddha are using the operation capacity of GPU in great quantities, this kind of method saves next a good dog crates large breed deal of funds not only, more make the time of operation from a year cut to a week.
The GraphicProcessingUnit of English full name of GPU, chinese interpreter is " graphical processor " . GPU is opposite a concept at CPU, because be in contemporary computer, especially family the best selling dvd discovery expenses system, the fever of game is friendly people become more and more important to graphical processing, need a special graphical core proc dog stairs essor, GPU emerge as the times require.
All the time since, the competition of GPU industry is far the competition that compares CPU comes intensely. At present the CPU of general PC has Intel and AMD only two big plants. And what precede in GPU respect is NVIDIA and ATI(already were bought by AMD) two manufacturers, but in can be being produced low end of the product still have several firms such as Intel, 3S. Although the product of these manufacturers is inferior to NVIDIA and ATI, but the need that also can satisfy an user in respect of a lot of application. More or less does the place of NVIDIA and ATI have some of altitude so deeply cold, develop ahead whip and spur only, ability is not overtaken by the successor.
Advanced him technology that why to use GPU as to the CPU manufacturer such as Intel invests product line, because eliminate original product product line too,be, the capital that invests possibly at the outset repeatedly calls in hard. And GPU manufacturer is him design only, seek production of other firm acting work again, do not have the pressure of product line.
because such, two big plants can throw NVIDIA and ATI more capital are on research and development, make GPU technology fast promote, then lets hemp save the research group of grain industry and Ha Fo, saw the possibility that allows computer to realize emulation cerebra vision to know differentiate.
GPU develops CPU of swift and violent Yuan Chao
Be in early in fact 2003, bound of science and technology has seen a lot of informations that replace CPU about using GPU. Of after this 2005, masschusetts Institute of Technology shared this work in. The graph of this university studies the group appli the best selling dog crates largeed array case type to check GPU to replace the function of CPU, and test result is exceeding and breathtaking.
In the test program that uses at that time, the group used Intel C++ to compile implement will optimize Cheng transcending a line and SSE instruction, and of above move can finish 16 with 32 floating-point operation. 2005, panel members have a test to a few A TIX800 XT and NVIDIA GeForce 6800G PU, the result of generation and the result that a 3.4 GHz Pentium IV PC produces undertake comparative discovering, performance is very excellent.
2008, andy Keane of general manager of department of career of computation of NVIDIA company Tesla expresses, to 2010, use the super computer that NVIDIATesla GPU compose builds, hopeful enters the whole world before 10 of pop chart of high-powered computer TO P500.
norton internet antivirusHe speaks of at that time, 10 series G PU is first NVIDIA processor that has double precision. As rapid development, the function of prospective G PU can break up every year one time commonly, function of prospective double precision will compare current rate at least 5 times faster.
Besides function promotion, the cost, power comsumption, main factor that covering an area of an area also is care of place of user of large-scale super computer.
The super computer that uses so like Belgian Antwerp university has 512 processor nucleuses, cost is 5.3 million dollar, took up several machine ark; Will change the table system that owns 8 G PU into after that, function comparatives, cost wants 7000 dollars only, cover an area of an area to also decrease greatly.
Person head, computer mutual " promote "
As we have learned, on the pop chart of TOP 500 of newest first phase that published in November 2008, the best achievement of NVIDIA Tesla is the 29th. This covers a name to be " TSUBAME " the system combines development by NEC and SUN company, used " CPU+GPU " mixture framew dvd discovery ork, include many 30 thousand AMD Opteron and kernel of Intel Xeon processor, and server of 170 T EslaS1070 1U, installation is in university of Japanese Tokyo industry, linpack testability can be every second 77.48 trillion (TFlops) , theoretical peak value is close to every second 170 trillion times. mountain t shirts
Before this, information of science and technology of whole world of Tokyo industry university and SatoshiMatsuoka of computational center director ever expressed, the computational platform that Tokyo labour is studying to did not come all the time greatly, discovery wants real at present the function of one pace spans, must use technology of G PU computation. "Our application checks discovery, tesla GPU offerred what the place before us did not see to be compared quickly, and spent a week time to finish GPU system deploy only. And spent a week time to finish GPU system deploy only..
This year in year, NVIDIA CEO Huang Renxun more express, 2009 is GPU is detonated year, GPU can let WIN7 relatively XP has 5-10 in a few application the promotion of times. DirectXA PI can offer very the effect of cruel, operation of individual of CPU+GPU operation open is new 2009 times.
"GPU operation times has come, this needs everybody to assist in all a grand occasion. " this banquet word is Huang Renxun is in NVIDIA and Microsoft hand in hand, fair below the setting that WIN7 newest operating system obtains clasp at numerous, announced from the angle of civil market the high speed of GPU develops.
Below the setting most popular selling dog crates large that develops in GPU technology high speed, what say before no less than, study the group hopes by means of considers this to be able to create the artificial intelligence that gives emulation cerebra vision to differentiate. And perfect software development increasingly as them, when be close to the result that human cerebra differentiates more, can understand cerebrum more conversely again run mode, also can let computer be run at the same time more like cerebrum.
Viewpoint: Future your family expenses computer, hopeful realizes person brain function
All the time since, game is the strong point of NVIDIA GPU, "We still can continue to throw tremendous energy on game in the future. More important is, it still can promote the innovation of computer industry, because we are OK, game domain application of background of experience reachs brand-new come in the domain. " NVIDIA respect says so.
This makes undoubtedly future of fa dog stairs and ramps mily expenses computer also has an opportunity to person head " draw close " bury played a hint foreshadowing later developments in a story.
Look nevertheless from current technical gradual progress, although had determined direction, but the process that grows through comparativing even. Before this, the top end that AMD (ATU) uses him the cerebra of core framework RV 770 and mankind spread out a c the best selling dog stairsontrast. The result shows, the computational ability of RV 770 and memory bandwidth are 1TeraOps(every second -727379968 times to operate respectively) with 1Tb/s, and person head is 100TeraOps and 10Eb/s, than RV 770 tower above 100 times with 10000 times. Energy is used up on, odd core RV770 needs 150W, but person head needs 30W only, such looking, person head is high-powered and efficient be RV 770 400 multiple.
Attention: GPU battlefield a collection of illustrative plates
memory card digital camerasCharacter of place of preamble of no less than, GPU market competition is far abominable at CPU. What face the market as each brand nevertheless is different, also have each vivid way each. Also not be the company of business of GPU of each furniture equipment nevertheless, pass very moistly.
1 Intel (Intel)
Intel not only it is the biggest CPU production distributors on the world, also be distributors of the world's greatest G PU production actually. The G PU of Intel is compositive completely at present show clip, be used at Intel advocate board the jotter with Intel.
2 NVIDIA
At present the biggest independence shows businessman of calorie of produce and sale, its show card to include Geforce series, NVIDIA sells solidify to be in as much advocate board those who go up is compositive show clip, these show clip as advocate board a put on sale, but as a result of the oneself after AMD annex ATI advocate board chip abilit the most popular selling dog stairs y rises, NV advocate board the picture of at the summit of one's power already not answer exist.
3 AMD(ATI)
The 2nd big independence shows card to produce distributors, its predecessor is ATI, also be the direct competitor with the biggest NVIDIA. As a result of AMD annex ATI hind, its advocate board the market extends quickly, had captured NV is in Amd processor advocate board half of country.
4 Matrox
Contend for a company of share of the independent market that show clip together with NVIDIA, ATI in those days, fade out of civil independence to show calorie of market at present. But the position that shows calorie of respect to have his with major in the project. Its major shows those who block sortie is 2D domain CAD.
5 Sis and Via
Selenium all (Sis) He Weicheng (the two companies that Via) ever was departure, produce oneself advocate board compositive show clip. But they had faded stage by stage advocate board the market.
