Aurora may be visible again Saturday night

The aurora may be visible in the sky again Saturday night, depending upon the weather, federal forecasters said.

Severe and extreme geomagnetic storms associated with coronal mass ejections, or solar eruptions, are likely Sunday, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.

When the material from the sun arrives at Earth, it can cause a geomagnetic storm. During the storm, an aurora may be visible. An aurora is a natural electrical phenomenon characterized by shimmering lights in the upper atmosphere at night, usually near the northern or southern magnetic pole. They happen when energetic particles from the sun interact with atoms in the upper atmosphere.

Aurora may be visible in sky

It appears that the chances are low in Tennessee, but an aurora may be visible in the sky over the northern half of the country this weekend, and possibly as far south as Alabama.

The National Weather Service Space Weather Prediction Center has issued a watch for a severe geomagnetic storm, saying it is possible later in the day Friday and continuing through the weekend. At least seven Earth-directed coronal mass ejections are in transit, the NWS said.

However, “exact timing remains somewhat uncertain,” forecasters said.

A coronal mass ejection is a solar eruption. When the solar materials arrive at Earth, a geomagnetic storm can result.

The National Nuclear Security Administration has signed a $600 million contract with Cray Inc. to build the first exascale supercomputer for the NNSA at Lawrence Livermore National Laboratory in California.

It is one of three exascale systems to be built at U.S. Department of Energy or NNSA laboratories. The other two exascale machines will be at DOE laboratories: Aurora at Argonne National Laboratory near Chicago and Frontier at Oak Ridge National Laboratory.

ORNL currently has the most powerful supercomputer in the world, Summit, and LLNL has the second-fastest, Sierra. They are both petaflop systems. Summit is capable of 200 petaflops, or 200,000 trillion calculations per second.

All three of the new exascale supercomputers will be built by Cray using their Shasta architecture, Slingshot interconnect, and new system software platform, the NNSA said in a press release Tuesday.

An exascale computer will be able to solve calculations up to 50 times faster than today’s top supercomputers, exceeding a quintillion, or 1018, calculations per second. That’s a billion billion calculations per second.

The U.S. Department of Energy on Tuesday announced a contract with Cray Inc. to build the Frontier supercomputer at Oak Ridge National Laboratory. It is expected to be the world’s most powerful supercomputer when it debuts in 2021.

The contract with Cray is valued at more than $600 million for the system and technology development, a press release said.

Energy Secretary Rick Perry was at ORNL on Tuesday morning to make the announcement.

“This is a big deal,” Perry said. “Frontier’s record-breaking performance will ensure our country’s ability to lead the world in science that improves the lives and economic prosperity of all Americans and the entire world. Frontier will accelerate innovation in AI (artificial intelligence) by giving American researchers world-class data and computing resources to ensure the next great inventions are made in the United States.”

Besides the supercomputing announcement on Tuesday, Perry also delivered the keynote speech at InnovationXLab: Advanced Manufacturing Summit at ORNL.

Frontier is expected to perform at greater than 1.5 exaflops. It will be able to solve calculations up to 50 times faster than today’s top supercomputers, exceeding a quintillion, or 1018, calculations per second, the press release said. That’s a billion billion calculations per second.

Oak Ridge Today has previously reported that Frontier would be built at ORNL. But the contract with Cray and its value and the specific performance estimate of more than 1.5 exaflops are all new announcements. The contract award includes technology development funding, a center of excellence, several early-delivery systems, the main Frontier system, and multi-year systems support. The Frontier system is expected to be delivered in 2021, and acceptance is expected in 2022.

Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

DOE announces $1.8 billion program for new supercomputers, with one at ORNL

The U.S. Department of Energy announced a new supercomputing program on Monday that could be worth up to $1.8 billion and deploy two systems, with one at Oak Ridge National Laboratory, that would be 50 to 100 times more powerful than today’s computers.

The new systems are called exascale computers. DOE said the new supercomputers will solidify United States leadership in exascale computing.

The initiative was announced by U.S. Energy Secretary Rick Perry in Washington, D.C., on Monday. Perry announced a request for proposals, or RFP, for the development of at least two new exascale supercomputers to be deployed at DOE national laboratories sometime around 2021-2023.

“The new supercomputers funded through this RFP will be follow-on systems to the first U.S. exascale system authorized by Secretary Perry this past June, named Aurora, which is currently under development at Argonne National Laboratory and scheduled to come online in 2021,” a press release said. The RFP announced Monday envisions the possibility of upgrades to Aurora or even a follow-on system in 2022-2023, “depending on an assessment of needs and opportunities at that time.” [Read more…]

Oak Ridge National Laboratory on Wednesday said it is building the world’s smartest supercomputer.

The new supercomputer is called Summit. It will be located in a new data center next to Titan, which is now the fourth most powerful supercomputer in the world.

Summit will be 5-10 times faster than Titan, ORNL said. It will move data five to 10 times faster, store eight times more data, and perform many more calculations simultaneously than Titan, the lab said in information provided by spokesperson Morgan McCorkle.

Summit will be the world’s smartest supercomputer because of its enormous memory and data handling capabilities as well as its unique machine learning processor design, McCorkle said.

“The first of Summit’s cabinets arrived Monday, and our team is in the process of uncrating and putting them in place,” McCorkle said in response to questions from Oak Ridge Today. [Read more…]

New 200-petaflop supercomputer to succeed Titan at ORNL

A new 200-petaflop supercomputer will succeed Titan at Oak Ridge National Laboratory, and it could be available to scientists and researchers in 2018, a spokesperson said this week.

The new IBM supercomputer, named Summit, could about double the computing power of what is now the world’s fastest machine, a Chinese system named Sunway TaihuLight, according to a seminannual list of the world’s top supercomputers released in June.

Sunway TaihuLight is capable of 93 petaflops, according to the list, the TOP500 list. A petaflop is one quadrillion calculations per second. That’s 1,000 trillion calculations per second.

Summit, which is expected to start operating at ORNL early in 2018, is one of three supercomputers that the U.S. Department of Energy expects to exceed 100 petaflops at three U.S. Department of Energy laboratories in 2018. The three planned systems are:

  • the 200-petaflop Summit at ORNL, which is expected to be available to users in early 2018;
  • a 150-petaflop machine known as Sierra at Lawrence Livermore National Laboratory near San Francisco in mid-2018; and
  • a 180-petaflop supercomputer called Aurora at Argonne National Laboratory in Chicago in late 2018.
