Supercomputer Research Enhances Energy Model Accuracy

Imagine a world in which an energy model can attain cost savings, security, and sustainability in our buildings. It is the goal of Oak Ridge National Laboratory researchers working on a project using UT’s Nautilus supercomputer. Called the Autotune methodology, the project is playing an important role in placing the bargain of energy efficiency within reach for more commercial and residential buildings. Current energy model exist but lack accuracy.

Scientists Solve Mercury Mystery

By identifying two genes required for transforming inorganic into organic mercury, which is far more toxic, UT and Oak Ridge National Laboratory (ORNL) scientists today have taken a significant step toward protecting human health. The question of how methylmercury, an organic form of mercury, is produced by natural processes in the environment has stumped scientists for decades, but a team comprised of four researchers at UT has solved the puzzle.

New Leader Named to UT-ORNL Supercomputer Center

Tony Mezzacappa

Tony Mezzacappa, a leader in the field of astrophysics and supernova science, has been named director of the Joint Institute for Computational Sciences at UT and Oak Ridge National Laboratory. Mezzacappa is a world leader in computational astrophysics and a pioneer in the field of supernova science.

UT Study: Unexpected Microbes Fighting Harmful Greenhouse Gas

The environment has a more formidable opponent than carbon dioxide. Another greenhouse gas, nitrous oxide, is 300 times more potent and also destroys the ozone layer each time it is released into the atmosphere. Luckily, nature has a larger army than previously thought combating this greenhouse gas—according to a study by Frank Loeffler, Governor’s Chair for Microbiology, and his colleagues.

UT’s Beacon Named Greenest Supercomputer

UT’s supercomputer, Beacon, may not be the fastest but it is the greenest. It was listed at the top of the Green500 which ranks the most energy-efficient supercomputers in the world.

IOP Science: Publisher’s Pick

An article co-authored by UT’s Joint Institute of Computational Sciences and oak Ridge National Laboratory researchers has earned recognition from IOP Science. The article conveys details of the research team’s investigation of a physics-based method of DNA sequencing, which is intended to read the hereditary traits coded in human DNA.

WSJ: Supercomputer Ranking Offers Clues About Chips, China

Jack Dongarra, distinguished professor in the electrical engineering and computer science department, was written about in the Wall Street Journal. Dongarra’s Top500 list which ranks the world’s fastest supercomputers was released this week listing Oak Ridge National Laboratory’s Titan at the top.

Professor Releases Supercomputer TOP500 Rankings

It’s official. UT researchers have access to the world’s fastest supercomputer enabling them to tackle the world’s toughest challenges. The “TOP500″ list ranking the world’s fastest supercomputers was released today, listing Oak Ridge National Laboratory’s massive new system, named Titan, as the fastest computer. The list is published twice yearly by a collaboration between Jack Dongarra, distinguished professor in the Department of Electrical Engineering and Computer Science, and colleagues at Lawrence Berkeley National Laboratory and the University of Mannheim.

Washington Post: Oak Ridge and NVIDIA unveil Titan supercomputer

The U.S. Department of Energy’s Oak Ridge National Laboratory unveiled their new flagship computer, Titan, on Monday. The Department also announced its latest round of Innovative and Novel Computational Impact on Theory and Experiment award recipients. Titan is ten times more powerful than its predecessor, Jaguar, with a theoretical peak performance of twenty petaflops, or 20,000 trillion calculations per second.
