Students Training for Computing Event

Some very computer-savvy UT and area high school students are training with UT faculty mentors for the Student Cluster Competition, which is part of the SC14 conference, the world’s largest high-performance computing event.

Kraken Refining Earthquake Models

Californian and Swiss researchers have been using the Kraken supercomputer to model what would happen if a major earthquake hit the southern portion of the San Andreas Fault. The entire fault extends more than 800 miles, from San Francisco to Southern California. What makes these researchers’ work different from previous studies is that they’ve factored in “nonlinear behavior of rocks”—a phenomenon that could reduce the velocity of ground motion predicted by previous computer models.

Supercomputer Research Sheds Light on the Death of Stars

Supernovae exhibit the most-energetic explosions, dispersing elements that make life possible into the universe. However, the energy source for the violent death of these massive stars is not known. Researchers using UT’s Kraken supercomputer have created three-dimensional simulations that have made great strides in uncovering the source.

Researchers Use Kraken to Understand Weather and Climate

Severe weather raises questions about the phenomena that cause it. The answer to all questions is atmospheric conditions. The atmosphere consists of varying layers of gases or fluid structures. Researchers at the National Institute for Computational Sciences are using the supercomputing power of UT’s Kraken to model how the structures interact to help prepare accurate weather forecasts and climate predictions.

HPCWire: Tackling Nanoscale Materials with Kraken

Jacek Jakowski, a computational scientist at the National Institute for Computational Sciences, was interviewed on an HPCWire podcast about a new computational capability he and his team developed to study the dynamics of prospective energy materials under diverse environmental situations. The researcher discussed  how he and his team are  using the Kraken supercomputer to explore

New Supercomputing Method Helps Energy and Materials Research

Research being done on the supercomputer Kraken holds promise for overcoming limitations in the study of energy and materials applications. The method employs quantum mechanics to understand how nuclear effects change the dynamics of microscopic-size materials.

UT Team Heads to Supercomputing Competition

A team of four UT students along with a student from Hardin Valley Academy and Oak Ridge High School are heading to Denver to compete in the SC!13’s international student supercomputing cluster competition. The competition is designed to introduce the next generation of students to the high powered computing community.

Supercomputer Work Makes Stride in Biofuels Research

Cellulase enzymes found in nature from sources such as wood-degrading fungi or in cows’ stomach compartments form one of the key catalysts for breaking down plant biomass to make biofuels. But, they remain quite expensive. Compute allocations from the Extreme Science and Engineering Discovery Environment (XSEDE) have made a breakthrough possible that could have big cost implications.
