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.
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.
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
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.
Many newly formed stars are surrounded by what are called protoplanetary disks, swirling masses of warm dust and gas that may potentially become celestial bodies such as planets and asteroids. Researchers are using the supercomputing power of Kraken to understand how these gases make this transformation.
Proteins can play either pernicious or positive roles in the dynamics of disease. Some proteins that anchor to cell membranes promote the development of HIV (human immunodeficiency virus), while some proteins thwart the growth of cancer, for example.
UT and its supercomputer, Kraken, were mentioned in the New York Times profiling high school-aged scientists competing in the nationwide Intel Science Talent Search. One of the teens was 17-year-old Mayuri Sridhar who “carries a SecurID device, which allows her to connect her laptop with Kraken, a supercomputer at the University of Tennessee that can
Two UT biochemistry, cellular, and molecular biology faculty members may have uncovered why some people respond to drugs differently. Jerome Baudry and Yinglong Miao, joint faculty at Oak Ridge National Laboratory, used supercomputer simulations at ORNL to give them unprecedented access to a key class of proteins involved in drug detoxification.
UT Knoxville’s supercomputing capabilities are about to become more powerful. The UT-managed National Institute for Computational Sciences is adding 300 teraflops to the TeraGrid’s total computational capability thanks to two awards from the National Science Foundation which total $3.4 million.
East Tennessee is now home to two of the world’s three fastest computers, according to new rankings released today. The Top500 list of the world’s fastest supercomputers places UT supercomputer Kraken in third place, where it also holds the title of world’s fastest academic supercomputer, while ORNL’s Jaguar computer took first place overall.
