WASHINGTON [url=http://www.nikejustdoitpascher.fr/homme-nike-air-max-97-ul-17-hal-noir-pas-cher.html]Homme Nike Air Max 97 UL'17 HAL Noir Pas Cher[/url] , June 19 (Xinhua) -- China's Sunway TaihuLight and Tianhe-2 are still the world's fastest and second fastest machines, but America's Titan was squeezed into fourth place by an upgraded Swiss system, according to the latest edition of the semiannual T0P500 list of supercomputers released Monday.

Sunway TaihuLight, described by the T0P500 list as "far and away the most powerful number-cruncher on the planet," maintained the lead since last June, when it dethroned Tianhe-2, the former champion for the previous three consecutive years.

It means that a Chinese supercomputer has topped the rankings maintained by researchers in the United States and Germany for nine times in a row.

What's more, Sunway TaihuLight, with a performance of 93 petaflops, was built entirely using processors designed and made in China.

"It highlights China's ability to conduct independent research in the supercomputing field," Haohuan Fu, deputy director of the National Supercomputing Center, where Sunway TaihuLight was installed, told Xinhua.

"China is simultaneously developing hardware and software technologies of supercomputers," Fu said. "It is expected that rapid development in homegrown hardware technologies, supported by homegrown software, will lead to a stronger research and engineering test capacity in many fields, thus promoting an industrial upgrading and, eventually, a sustainable development of China's homegrown supercomputing industry."

Tianhe-2, capable of performing 33.9 petaflops, was based on Intel chips, something banned by the U.S. government from selling to four supercomputing institutions in China since 2015.

In the latest rankings, the new number three supercomputer is the upgraded Piz Daint, a system installed at the Swiss National Supercomputing Center.

Its current performance of 19.6 petaflops pushed Titan, a machine installed at the U.S. Oak Ridge National Laboratory, into fourth place. Titan's performance of 17.6 petaflops has remained constant since it was installed in 2012.

"This is the second time in the 24-year history of the TOP500 list that the United States has failed to secure any of the top three positions," the TOP500 organizers said in a statement.

The only other time this occurred was in November 1996, when three Japanese systems captured the top three spots.

"Nevertheless, the U.S. still claims five of the top 10 supercomputers, which is more than any other nation," they said.

Fu called the upgraded Swiss system "really a surprise," saying that "it reflects the increased investment in large-scale supercomputers in Europe."

"Although the U.S. dropped out of the top three, it still has strong strength in high performance computing," Fu told Xinhua. "If everything goes well, we could see two U.S. systems with a performance of 200 to 300 petaflops in the next rankings at the end of the year."

Just days before the TOP500 announcement, the U.S. Department of Energy said it has awarded AMD, Cray, HP Enterprise, IBM, Intel and NVIDIA a total of 258 million U.S. dollars in funding to accelerate the development of next-generation supercomputers.

At the moment, you simply won’t stumbled upon a fixed diabetic diet plan for people with diabetes, but the truth is that you are going to find the general recommendations of what’s best to eat. Nevertheless, the diabetic foods meal focus on the requirements of individuals and there’s no lack of help and advice simply because it tells you what’s good or bad for a diabetics.

At some time most consumers become confused due to the wide choice of options that are available. This will likely result in difficulties as they try to figure out which foods should be included in a healthy diabetic diet plan.

Instead of remaining focused on foods that diabetics should eat, the main subject of this article is to help show you the types of foods that are not going to be helpful for those who have been diagnosed with diabetes.

To put it simply, a low glycemic diet is one that includes a reduction of foods with unhealthy fats and high levels of carbs. Sugar-free food choices; regular exercise and maintenance of normal blood glucose levels are also suggested.

In an effort to preserve ideal blood sugar levels, your meals for diabetics needs to be healthy and balanced along with the proper amount of necessary protein, fats, fruits and carbohydrates.

The meals containing carbs are also going to offer selections such as fresh fruits, glucose, fresh vegetables, along with whole grains like rice and wheat. It takes longer for healthy proteins and complex to be digested and for this reason these food groups will affect the circulating blood glucose level more slowly.

One example of this is seen when comparing ice cream to potatoes. Ice cream elevates the blood sugar quickly and dramatically yet when you eat potatoes the change in your glucose level will be slower and less dramatic.

It is imperative that a person with diabetes should avoid the overly processed carbohydrates found in most packaged foods. This includes junk food, white flour bread and other products made with white flour. These are foods that have high glycemic index values that will result in elevated blood glucose readings.

Another clever step is to avoid those cakes, muffins and pastry products that are marketed specifically for diabetics.
