Sandia computational researchers awarded $2.6 million in grants from DOE Office of Science

October 27, 2010 • ALBUQUERQUE, N.M. — Four Sandia researchers have been awarded three-year grants totalling $2.6 million from the Department of Energy’s Office of Science to pursue computational research proposals that would help create an exascale computer. An exascale computer would be 1,000 times faster than a petascale computer, the fastest now available,...

Red Sky/Mesa wins Oracle green award

September 22, 2010 • ALBUQUERQUE, N.M. – Red Sky/Red Mesa, listed by Top500 Supercomputer Sites as the 10th fastest computer in the world, has been selected as one of the 15 winners of Oracle’s Enable the Eco-Enterprise award. “Red Sky/Red Mesa is the most eco-transparent (energy efficient) compute platform Sandia has deployed to date,”...

Breaking the logjam: improving data download from outer space

May 18, 2010 • ALBUQUERQUE, N.M. — Satellite systems in space keyed to detect nuclear events and environmental gasses currently face a kind of data logjam because their increasingly powerful sensors produce more information than their available bandwidth can easily transmit. Experiments conducted by Sandia National Laboratories at the International Space Station preliminarily indicate...

More chip cores can mean slower supercomputing, Sandia simulation shows

January 12, 2009 • 16 multicores perform barely as well as two for complex applications ALBUQUERQUE, N.M. — The worldwide attempt to increase the speed of supercomputers merely by increasing the number of processor cores on individual chips unexpectedly worsens performance for many complex applications, Sandia simulations have found. A Sandia team simulated key...

Sandia supercomputers offer new explanation of Tunguska disaster

December 17, 2007 • ALBUQUERQUE, N.M. — The stunning amount of forest devastation at Tunguska a century ago in Siberia may have been caused by an asteroid only a fraction as large as previously published estimates, Sandia National Laboratories supercomputer simulations suggest.
