Oak Ridge National Laboratory regained the lead in high-performance computing, enjoyed record-setting recognition for its research, and became a showpiece for renewable energy technology during 2012.

The U.S. Department of Energy’s Office of Science reciprocated with favorable marks in its annual appraisal of managing contractor UT-Battelle. DOE cited the laboratory’s operation of its scientific user facilities, its “delivery of impactful science,” and a successful workforce restructuring to reduce operating costs.

“The dedicated efforts of our laboratory staff in all phases of science and technology and operational support have resulted in an excellent record of delivering science to the nation in 2012,” said ORNL Director Thom Mason. “ORNL will continue to set the pace in research toward a clean and secure energy future.”

ORNL’s 2012 included achievements in both research and support.

UT study predicts extreme climate in eastern United States

From extreme drought to super storms, many wonder what the future holds for the climate of the eastern United States. A study conducted by researchers at the University of Tennessee in Knoxville does away with the guessing.

Results show the region will be hotter and wetter.

Joshua Fu, a civil and environmental engineering professor, and Yang Gao, a graduate research assistant, developed precise scales of cities that act as a climate crystal ball, seeing high-resolution climate changes almost 50 years into the future.

The study found that heat waves will become more severe in most regions of the eastern United States and that both the Northeast and Southeast will see a drastic increase in precipitation.

The No. 1 ranking for the new Titan supercomputer, designating it as the most powerful in the world, was clearly appreciated in East Tennessee on Monday.

But even as they celebrated a return to the top spot, scientists at Oak Ridge National Laboratory, where the giant computer is based, said they are focused more on research than rankings.

“We love being No. 1,” said Bronson Messer, acting group leader for scientific computing at the National Center for Computational Science at ORNL. “It’s great recognition. But what really matters is what science will do with the machine.”

New Titan supercomputer debuts at ORNL

The Oak Ridge National Laboratory launched a new era of scientific supercomputing today with Titan, a system capable of churning through more than 20,000 trillion calculations each second—or 20 petaflops—by employing a family of processors called graphic processing units first created for computer gaming. Titan will be 10 times more powerful than ORNL’s last world-leading system, Jaguar, while overcoming power and space limitations inherent in the previous generation of high-performance computers.

Titan, which is supported by the U.S. Department of Energy, will provide unprecedented computing power for research in energy, climate change, efficient engines, materials, and other disciplines, and pave the way for a wide range of achievements in science and technology.

UT, ORNL lead national project to study nuclear fusion reactor materials

A research team at the University of Tennessee and Oak Ridge National Laboratory will receive $4.1 million during the next five years to study materials used in nuclear fusion reactors.

The funding is part of a larger $11.5 million U.S. Department of Energy project that includes seven other laboratories and universities across the country.

The goal is to help convert nuclear fusion, which promises an “almost limitless supply of clean and safe energy,” into a practical, commercial power source, a UT press release said.
