China to export 20 locomotives to Germany
2018-06-25 11:16:07Global Times Editor : Li Yan
High quality, low cost give domestic company the edge
China's CRRC Zhuzhou Locomotive Co Ltd has signed a framework agreement with Germany's Deutsche Bahn to export 20 hybrid shunting locomotives, the first time such machinery has been exported to the manufacturing giant.

A deal involving the first batch of four locomotives was also signed last week, according to a statement released by the Chinese company on its official WeChat account on Saturday.

CRRC Zhuzhou Locomotive and Deutsche Bahn jointly developed the new type of hybrid shunting locomotive in 2017. The first batch of locomotives have been built and will soon be shipped to Hamburg, Germany, the statement reads.

The hybrid shunting locomotives will run on Germany's railway network in accordance with local standards at speeds up to 100 kilometers per hour, said the company's Saturday statement.

"Germany is planning to upgrade its infrastructure, and railways are a focus in the new financial year," Cui Hongjian, director of the Department of European Studies at the China Institute of International Studies, told the Global Times on Sunday.

The deal shows China holds advantages in terms of both quality and pricing, Cui said.

China's high technological standards for electric and internal combustion locomotives and lower cost are reasons behind the deal, according to Sun Zhang, a railway expert and professor at Shanghai Tongji University.

This is the first time China's locomotives have been exported to Germany, marking recognition of China's railway products, said the company.

Germany is not the only destination in Europe for China's railway products. According to the statement, CRRC Zhuzhou Locomotive has exported electric locomotives to Serbia, shunting locomotives to Austria, bullet trains to Czech.

Sun noted that foreign railway markets have unique requirements making it inefficient for them to self-develop railway products that only meet their needs. China's vast experience and huge railway network allows it to make adjustments to meet the needs of most foreign railways, Sun told the Global Times.

Exporting railway technologies is crucial to the Belt and Road initiative as different countries are in need of different railway technologies, according to Sun.

China's growing expertise in infrastructure construction also enables domestic companies to play a bigger role in regions previously dominated by foreign enterprises.

An example of China's ability to innovate are the high-altitude locomotives domestically developed by CRRC Dalian Co Ltd, which are now in service on the Golmud-Lhasa Railway on western China's Qinghai-Tibet plateau, news website chinanews.com reported Friday.

The Golmud-Lhasa Railway plans to replace all imported locomotives with domestic ones in the future, said the website.

MANILA -- Globe Telecom's GCash and AlipayHK on Monday launched a blockchain-powered remittance service that promises lower fees and transfers within seconds, the Filipino telecommunications firm said.

Transaction fees will be waived during a 3-month trial period. Users can send and receive money on their digital wallets by just tapping on their mobile devices, Globe said in a statement.
Standard Chartered Bank is the "core partner" lender for the service, according to the statement. The service is encrypted with the "most advanced protocols," it said.

Hong Kong is among the top markets for overseas Filipinos in East and Southeast Asia, alongside Malaysia and Singapore.

Remittances account for roughly a tenth of gross domestic product, according to Bloomberg. In June cash remittances reached $2.3 billion.

well done yankees!! +american systems are far away more energy efficient



I find this actually quite unimpressive on the part of the US. I knew this year, there was a great likelihood that the US would briefly recapture the supercomputing title. I thought there was a high probability that China would slip to #3 and #4. Summit and Sierra have been in the works for a very long time and now, I see that they're both essentially the same design. A year ago, there were talks about Summit being as powerful as 300 pf and Sierra 150 pf. Now I see that the performance of both were greatly exaggerated by rumors. Even weeks before the official list today, Summit was said to be in the 200 pf league. And what did they turn out to be? Summit: 187pf and Sierra: 119pf. Sierra failed to push Taihulight down to third. Very underwhelming performance for the US considering that this was supposed to be the year that the US really shines with its new toys and China still in the development cycle before its superior machines debut, but even under such circumstances, the US really only got ahead a little. In the world of supercomputers where progress is often in magnitudes, this is not much at all.

As for China, always modest with the projections: Tianhe-2's upgrade was supposed to place it at 95pf and instead, it gets over 100. When China's Tianhe-3 prototype debuts later this year, we'll see some real muscle.

All the three Chinese computing centers are busy making exascale which will be 5 times more powerful than summit.

However, I would bet 2019 (June) to be the time when some Chinese computer (early production model) reclaims the crown. Remember, Tianhe-3 prototype (as shown) has only 3 cabinet, if it is all the prototype has it is not the full size of the final product (much smaller). This would mean that the prototype is for verification purpose. One can get a very high unit performance (higher than any other systems including Summit), but total performance would be much lower. The final product should consists of tens (close to hundreds of cabinets).

What I suspect is, in the next 6 months, Tianhe3 prototype will verify all architecture design goals with minimum number of nodes. During 2019, more nodes will be added to gradually reach 1000 PF in 2020. Somewhere in 2019 (say June before the TOP list), Tianhe 3 would have reached speed much higher than 200PF (400 to 600) to secure 1000PF in 2020 which is the plan. Whether the Chinese want to push for a 300 PF by the next (Nov 2018) TOP listing depends on how much attention they pay to the list (more political than scientific).

Chinese experts view China-U.S. competition in supercomputer with forward-looking attitude

IBM's supercomputer Summit has overtaken China's Sunway TaihuLight to become the world's fastest, with the U.S. reclaiming the number one spot.

The Top500 supercomputer list was revealed on Monday, and experts said they were not surprised that Summit won this round due to the intense competition between the United States and China in the field of supercomputers.

"It may put us under more pressure and encourage us to engage more in innovation," said Fu Haohuan, deputy director of the Chinese National Supercomputing Center based in Wuxi, Jiangsu Province.

"For us, what is more important is to seek development with a down-to-earth attitude," Fu added.

Summit, recently unveiled at the U.S. Department of Energy's Oak Ridge National Laboratory in Tennessee State, captured the number one spot with a performance of 122.3 petaflops on high-Performance linpack (HPL), the benchmark used to rank the Top500 list, the statement said.

A petaflop is a measure of a computer's processing speed.

Shan Hongzhang, a computer scientist at the Lawrence Berkeley National Laboratory, told Xinhua that the structure of Summit potentially reduced the traditional performance overhead of transferring data between the central processing unit and graphics processing unit.

Summit is designed for research in energy, advanced materials and artificial intelligence (AI).

U.S. Secretary of Energy Rick Perry said Summit could have a profound impact in energy research, scientific discovery, economic competitiveness and national security.

Back when China was on top, supercomputer expert Qian Depei said little attention should be paid to the ranking.

"Ranking is not our ultimate goal in developing supercomputers," Qian told Xinhua at that time. "Our goal is to promote large-scale applications, solve the challenges faced by our country, and push for the progress of China's computer industry," he said.

Sunway TaihuLight, developed by China's National Research Center of Parallel Computer Engineering and Technology and installed at the National Supercomputing Center in Jiangsu, ranked number two after leading the list for the past two years.

Its HPL mark of 93 petaflops has remained unchanged since it came online in June 2016.

The number three spot goes to Sierra, a new system developed by the U.S. Department of Energy's Lawrence Livermore National Laboratory in California, delivering 71.6 petaflops on HPL.

China's Tianhe-2A, developed by the National University of Defense Technology and installed at the National Supercomputer Center in Guangzhou,moved down two notches to the number four spot. But a major upgrade of its hardware increased the system's performance from 33.9 petaflops to 61.4 petaflops.

The Top 500 list is considered one of the most authoritative rankings of the world's supercomputers. It is compiled on the basis of the machines' performance on the Linpack benchmark by experts from the United States and Germany.
