A multi-institutional team has discovered how ultra-thin lithium films on graphite walls control plasma behavior in nuclear fusion devices. The study reveals that oxygen plays a key role in bonding deuterium atoms, while lithium brings it to the surface.
A collaborative project by RDAV and University of Tennessee artist Evan Meaney has won the jury prize for Distributed Microtopias exhibition at FLEFF. The 'Null_Sets' artwork visualizes data size and structure using an open-source script, exploring the gap between data and information.
The Nautilus supercomputer at the University of Tennessee's RDAV Center has been upgraded with four new SGI UV 10 units, adding 128 cores and 512 GB of memory. This upgrade will enable more researchers to use high-performance computing (HPC) for data analysis.
The University of Tennessee's Beacon supercomputer, powered by Intel Xeon and Xeon Phi processors, achieved a world-record efficiency of 2.499 billion floating point operations per second per watt. The system used only 44.89 kW of power to produce 112.2 trillion calculations per second.
The study combines advanced supercomputing with a quarter-century of worldwide news to forecast human behavior. It predicts civil unrest, country stability, and the movement of individuals across the globe.
The University of Tennessee-managed NICS will add 300 teraflops and 200 million service units to the TeraGrid, increasing total available resources to over 800 million. Researchers can now access more resources, including the 166-teraflop Cray XT4 Athena, with improved availability for smaller jobs.
Kraken, the National Institute for Computational Sciences' supercomputer, has achieved petaflop performance, accelerating science and placing it among the top five computers in the world. The system enables researchers to simulate complex phenomena such as core-collapse supernovas with unprecedented realism.
