According to the Wall Street Journal reported that United States Government issued export ban on Chinese hyper-technology. The ban discourages Chinese Super industry casts a shadow. Jeremy Scott iPad Mini Case
China’s hyper-technological development over the past few years can be described as automatics. States had established four Super technique Center, Tianhe repeatedly, dawn, to win industry-Top500 ranking performance champion, burn it up. Among them, the national research and development institutions and Intel, Nvidia’s cooperation for the domestic Super contributions to the development of a very large force, then why no limit on such cooperation and in the past the United States Government suddenly announced the blockade against China?
Ultra is the core in the past most of the chips can be bought on the open market, which cannot be completely embargo. Years United States because this super technique development, China has all along failed to interfere. But as the industry changes, some new situation has emerged. Jeremy Scott iPad Mini Case
The key change is the rise of heterogeneous computing. Super common Xeon CPU is mainly used in the past to build, and HPC high performance tends to carry a lot of dedicated computing chip, such as the Xeon Phi, Tesla and FirePro. These chips yields less sold on not much, and special programming mode. Super study on institutions in order to accelerate the pace of development to chips business, half a year or even longer to get new generation computing chips that are not listed, and compile the latter is carried out with the help of system optimization.
Domestic Ultra, 2nd count of Tianhe is working with Intel, months in advance to get a Xeon Phi calculation card and completed the deployment. Xeon Phi Tianhe 2nd sale has finished running a test project to enter commercial operation phase. At that time responsible for the milky way project 2nd nudt communication with Intel, received a large number of programming, has successfully deployed system code. Without this partnership, not only the duration of Tianhe will greatly delay, due to the complexity of heterogeneous computing nudt is hard to complete the Super software debugging optimization tasks.
United States realize that the era of heterogeneous computing chip companies cooperate with ultra is manufacturing’s importance. As long as the cut off United States enterprises and institutions and cooperation between China and even which can be bought from the open market for the chips, also need to wait for the chips are put on sale to do; lack of chip designer’s Guide, Chinese Super projects find it difficult to take full advantage of chip performance, and with United States counterparts lost their advantage in a confrontation. As a result, United States will be able to regain the Super work performance champion, while China will encounter trouble. A case study of Tianhe, its plans to upgrade to next-generation Xeon Phi chips this year, continues to hold the Championship position, but suddenly, the ban will definitely affect the scheduled programme. Tianhe is likely to yield the performance this year of the King’s title.
United States corporate bans of course dissatisfied. Intel and the University of national defense cooperation has been good, Tianhe 2nd Xeon Phi also played a lot of advertising. Intel has just announced at IDF Forum building parallel computing Center in China, is aimed at enhancing Xeon Phi. Customers now gone, the loss of Intel is not small.
So, Chinese Super project able to replace imports with domestic chip technology?
Very early started to develop their own intellectual property rights in China, a super chip, successively gave birth to calculate the Godson, National Defense University federal and South of Port Dickson power processors. Early in 2008, Dawn Ultra is the project plan used in the calculations 8000-10000 Godson 3B CPU to build the first domestic petaflops HPC. Unfortunately the Godson 3B until dawn Ultra is short run only two years later, and the first problems of poor performance is not practical, and finally deployed 3000 only for research purposes. Nudt Tianhe Super is used to design intelligent CPU in University, but only on the Internet, not taking computing tasks. South Wayne Shen deployment on a single super is Kamui, the overall computing power is not very prominent.
Several domestic chip’s main problem is that their performance is far worse than those in United States rivals: single-chip floating point performance but 200G Flops, far better than next-generation Xeon E5 700G Flops more than Xeon Phi, Tesla many-core processors. And these homemade CPU memory performance is unsatisfactory, greatly limits the practical application performance. This is why Ultra is still made with imported chips and chips for homemade reasons that are not very cold.
If using these homemade chips to replace imported Xeon Phi, Tesla, you need to deploy more than 10 times the number of compute nodes in order to achieve the same performance. But the existing network technology to support 100,000 of thousands of nodes and efficient interconnection, in other words, this road is not feasible.
Chip wants to replace imports, China will have to develop top of heterogeneous computing. But making chips like a Xeon Phi has great difficulty: not to do a large number of interconnection between the core and high bandwidth memory system is hard to do; communication bus between the chips is very high. Domestic research institutions over the past few years in these technology areas have some exploration, level with Intel, Nvidia and other disparities. Want to catch up with the world-class level, to create a rival contemporaries Xeon Phi, Tesla chips without several years of time and money, human input is not enough. Many-core processors are being developed by the South is expected to set up a 1 billion extra is, but the nodes will not have very high efficiency, energy efficiency indicators.
Importing chips are not easy, domestic technology to mature for a short time, Chinese Super industry will usher in years of low ebb. Several times in a row to win the brilliant are hard to see in the coming years, Americans can only sit back and United States hegemony on the back. Current United States energy select Intel, Nvidia, IBM program ordered three 203 billion the size of Super, and will be delivered in the next two years. By 2018, United States will dominate the Super work performance charts.
United States blockade of a big boost to the Chinese Government’s policy: even if it is for “proud”, China also will ask a few big chips research institutions into the unprecedented resources to expedite the study process, and strive to get rid of the United States reliance on technology. Homemade chips United States embargo ushered in great development opportunities, speed will multiply faster. Under the country-driven, and years later China chip industry will rise as a force to be reckoned with, not only in the field of ultra is, but in the server, PC and mobile device industries with United States enterprises a full confrontation. From this perspective, the United States embargo on China is a piece of good news in the long run. No pressure, no power, the Chinese don’t want to have on it.
