A Chinese supercomputer has topped a list of the world's fastest computers for the seventh straight year -- and for the first time the winner uses only Chinese-designed processors instead of U.S. technology. The Sunway TaihuLight can run quadrillions of calculations per second, and is the first system to exceed more than 100 petaflops at peak performance. Monday's announcement marks a new milestone for Chinese supercomputer development and a further erosion of past U.S. dominance of the field. A Chinese supercomputer has topped a list of the world's fastest computers for the seventh straight year -- and for the first time the winner uses only Chinese-designed processors instead of U.S. technology. The Sunway TaihuLight achieves 93 Pflops on the Linpack benchmark, and has a peak performance of 125 Pflops.

As New Mexico lawmakers debate possible changes to the state's tax structure, one concern is whether purchases made by national laboratories located in the state will continue to result in gross receipts tax revenue. Data presented to lawmakers shows the for-profit consortium that currently manages Los Alamos National Laboratory has paid between $48 million and $100 million a year in gross receipts taxes.
As part of the transportation authorities' efforts to address this problem, researchers from across the US Department of Energy's (DOE) Argonne National Laboratory in collaboration with the Lawrence Berkeley National Laboratory (LBNL) have developed a new artificial intelligence model to help alleviate congestion on the city's streets. That data was then used to train a model to forecast traffics, congestion spots, and average speed of cars on the routes. The new model can look at the past hour, and then predict the next hour of traffic with great accuracy within milliseconds. "The AI and supercomputing capabilities that have been used in this work allow us to tackle really large problems. The scale of this project is large, and this amount of data requires an equally large computing resource to tackle it," said Prasanna Balaprakash, a computer scientist in Argonne National Laboratory.
The Cybercore Integration Center will host an advanced electronics lab that will be used for cybersecurity and infrastructure security research. The Collaborative Computing Center will house a "supercomputer" providing research capabilities that will benefit not only INL but universities and other institutions throughout Idaho thanks to their connection through the Idaho Regional Optical Network.
ALBUQUERQUE, NEW MEXICO – From the deserts of southern New Mexico and Nevada to islands in the Pacific Ocean, the U.S. government conducted dozens of nuclear weapons tests from the 1940s until the early 1960s. Vintage rolls of film collected from high-security vaults across the country show some of the blasts sending incredible mushroom clouds into the sky and massive fireballs across the landscape. Others start with blinding flashes of light followed by rising columns of smoke in the distance. A team from Lawrence Livermore National Laboratory this week published more than five dozen films salvaged from government installations where they had sat idle for years. Lab physicist Greg Spriggs said the decades-old films were in danger of decomposing and being lost to history.
