Top 50 Supercomputers

[onedomino]

A new list of the top 500 supercomputers has been published. Regarding the top 50 supercomputers, 45 were built by American companies. Of these, 35 are located in the US, 5 in Japan, 3 in the UK, and 2 in China. Switzerland, Netherlands, Spain, Canada, and Germany, each have one. The fastest supercomputer in Russia is ranked 56th and was manufactured by IBM. The fastest French supercomputer is ranked 77th and was manufactured by Hewlett-Packard.

End of the line for Roadrunner supercomputer
Mar 30,`13 -- It's the end of the line for Roadrunner, a first-of-its-kind collection of processors that once reigned as the world's fastest supercomputer.

The $121 million supercomputer, housed at one of the nation's premier nuclear weapons research laboratories in northern New Mexico, will be decommissioned Sunday. The reason? The world of supercomputing is evolving and Roadrunner has been replaced with something smaller, faster, more energy efficient and cheaper. Still, officials at Los Alamos National Laboratory say it's among the 25 fastest supercomputers in the world. "Roadrunner got everyone thinking in new ways about how to build and use a supercomputer," said Gary Grider, who works in the lab's high performance computing division. "Specialized processors are being included in new ways on new systems and being used in novel ways. Our demonstration with Roadrunner caused everyone to pay attention."

In 2008, Roadrunner was first to break the elusive petaflop barrier by processing just over a quadrillion mathematical calculations per second. Los Alamos teamed up with IBM to build Roadrunner from commercially available parts. They ended up with 278 refrigerator-size racks filled with two different types of processors, all linked together by 55 miles of fiber optic cable. It took nearly two dozen tractor trailer trucks to deliver the supercomputer from New York to northern New Mexico. The supercomputer has been used over the last five years to model viruses and unseen parts of the universe, to better understand lasers and for nuclear weapons work. That includes simulations aimed at ensuring the safety and reliability of the nation's aging arsenal.

This undated handout photo provided by IBM shows lead engineer Don Grice of IBM inspecting the world's fastest computer, nicknamed "Roadrunner", in the company's Poughkeepsie, N.Y. plant. It's the end of the line for the supercomputer that was once the fastest in the world and best known for breaking the once-elusive petaflop barrier. Roadrunner, the $121 million supercomputer housed at Los Alamos National Laboratory will be decommissioned on Sunday, March 31, 2013. The reason: The world of supercomputing is evolving. Roadrunner's replacement is faster, more energy efficient and less expensive.

As part of the U.S. nuclear stockpile stewardship program, researchers used Roadrunner's high-speed calculation capabilities to unravel some of the mysteries of energy flow in weapons. Los Alamos has been helping pioneer novel computer systems for decades. In 1976, the lab helped with the development of the Cray-1. In 1993, the lab held the fastest supercomputer title with the Thinking Machine CM-5. "And to think of where we're going to be in the next 10 to 15 years, it's just mindboggling," said lab spokesman Kevin Roark. Right now, Los Alamos - along with scientists at Sandia National Laboratories in Albuquerque and Lawrence Livermore National Laboratory in California - is using a supercomputer dubbed Cielo. Installed in 2010, it's slightly faster than Roadrunner, takes up less space and came in at just under $54 million.

Roark said in the next 10 to 20 years, it's expected that the world's supercomputers will be capable of breaking the exascale barrier, or one quintillion calculations per second. There will be no ceremony when Roadrunner is switched off Sunday, but lab officials said researchers will spend the next month experimenting with its operating system and techniques for compressing memory before dismantling begins. They say the work could help guide the design of future supercomputers.

Chinese Supercomputer World’s Fastest
June 20, 2016 - A Chinese supercomputer has been named the world’s fastest.

According to a list of the speediest computers in the world, published by TOP500, the Chinese Sunway TaihuLight is number one. The 93 petaflop computer runs on a Linux-based operating system and is capable of 93,000 trillion calculations per second, which is double the speed of last year’s top computer, the Tianhe-2, also Chinese. "Considering that just 10 years ago, China claimed a mere 28 systems on the list, with none ranked in the top 30, the nation has come further and faster than any other country in the history of supercomputing," according to Top500.

The Chinese TaihuLight supercomputer has been named word's fastest.​

China now has 167 computers in the top 500, surpassing the United States, which has 165. The TaihuLight is powered by a new ShenWei processor and is entirely made in China. According to a news release, it ends “remaining speculation that China would have to rely on Western technology to compete effectively in the upper echelons of supercomputing.”

TaihuLight is currently being operated at the National Supercomputing Center in Wuxi, China. It will be used in a variety of ways, from advanced engineering and manufacturing work to climate modeling. China also boasts the second fastest supercomputer on the list. The United States has four computers among the top 10, while others in the top 10 are in Japan, Switzerland, Germany and Saudi Arabia.
