The UT–Oak Ridge National Laboratory Joint Institute for Computational Sciences—and UT’s Office of Information Technology—have announced final plans to upgrade the bandwidth of UT’s wide area network for research and education to 100 gigabit per second (100G) capability by July 2014. This project makes UT an early adopter of the technology and will improve a
The Earth has a shield which can protect it from damaging solar particles. However, this shield can be infiltrated and the result can be a disruption of power grids and communications networks, and radiation on Earth. Researchers using supercomputers at the National Institute for Computational Sciences are creating a topological map of Earth’s magnetosphere, allowing
As disease progresses over space and time in the body, high-resolution imaging can capture the changes taking place down to the sub-cellular level; meanwhile, huge sets of hereditary (genomic) information hold clues about the dynamics of illness. Comparing certain characteristics in the images with genomic and clinical data may be key in predicting disease progression
Jack Dongarra, distinguished professor of computer science at UT is designing software that will be critical in making the next generation of supercomputers operational. For decades, supercomputers have been tackling the world’s most pressing challenges, from sequencing the human genome to predicting climate changes. But their power is limited and thus, so is our knowledge.
The way the power of supercomputers is measured is about to change. Since 1993, Jack Dongarra, distinguished professor of computer science at UT has led the ranking of the world’s top 500 supercomputers. The much-celebrated bi-annual TOP500 list is compiled using Dongarra’s benchmark system, called Linpack. But Dongarra says Linpack hasn’t kept pace with supercomputing
An article in The Times of India features China’s Tianhe-2 supercomputer, aka Milkyway-2, which recently measured at speeds of nearly 31 petaflops surpassing the current record holder by 74 percent, Ars Technica. The numbers were revealed by distinguished computer science professor Jack Dongarra, who introduced the computer speed measuring Linpack benchmarks, and who helps compile
Using supercomputing resources provided by the National Institute for Computational Sciences, a research team has made discoveries using computer modeling and simulations that have overturned longstanding, widely held beliefs about black holes.
As reported by Forbes, a supercomputer used by many UT professors and researchers will is getting a boost. Last November, Cray’s Titan Supercomputer, which is being used at Oak Ridge National Laboratory, earned the crown of World’s Fastest Supercomputer. Now Oak Ridge hopes to bolster the performance of that supercomputer by building the world’s fastest
During peak tornado season, researchers using supercomputers at the National Institute for Computational Sciences are working to revolutionize the ability to anticipate tornadoes by explaining why some storms generate tornadoes and others don’t. They are also developing advanced techniques for analyzing data to discover how the twisters move in both space and time.
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.
Research conducted using UT’s supercomputer, Nautilus, is uncovering the effects of expedited vegetation green-up in the greater Yellowstone ecosystem catalyzed by a warmer planet. Nautilus is managed by the National Institute for Computational Sciences (NICS) with resources and support provided by the Remote Data Analysis and Visualization Center of the institute.
The Remote Data Analysis and Visualization Center at UT’s National Institute for Computational Sciences has enhanced the web interface to a system that allows researchers to interact with sophisticated data about locations and relationships of life species across geographical areas. The improvements were built out of a pilot study project involving species distribution modeling in
