Brookhaven Lab Displays Stereo Visualization of "Big-Bang" Matter
and Other Computing Capabilities at SC99

UPTON, NY-If you want to see what matter looked like an instant after the beginning of the universe, stop by the U.S. Department of Energy's Brookhaven National Laboratory exhibit at the SC99 (Supercomputing) conference in Portland, Oregon, November 13 to 19. The exhibit will showcase the Lab's state-of-the-art computing capabilities, including a theoretical visualization of matter just microseconds after the Big Bang.

The visualization is based on data Brookhaven scientists expect to generate when they begin collisions of gold ions at the Lab's Relativistic Heavy Ion Collider (RHIC), officially commissioned on October 4. Gold ions will circle around RHIC's 2.4-mile track in opposite directions at nearly the speed of light. When they collide, they are expected to create a quark-gluon plasma, a state of matter not known to have existed since the birth of our universe.

Thousands of ion collisions per second are expected when RHIC is fully operational sometime next spring. Brookhaven's Center for Data-Intensive Computing (CDIC) was recently established to develop advanced techniques for processing, analyzing and storing such large volumes of data. It will help scientists study the quark-gluon plasma to gain a better understanding of the forms of matter that now exist.

In addition to the theoretical RHIC data, Brookhaven's SC99 exhibit will also demonstrate the role of stereoscopic visualization and contributions from the CDIC in the areas of computed microtomography, high-energy and nuclear physics, aerosol and climate studies, combustion chemistry and treatment planning for cancer therapy.

The conference is at the Oregon Convention Center in Portland. For more general information about the conference, see http://www.sc99.org or contact Mike Bernhardt or Laura Dahill at (503) 293-8480, info@bernhardt.com.

The U.S. Department of Energy's Brookhaven National Laboratory creates and operates major facilities available to university, industrial and government personnel for basic and applied research in the physical, biomedical and environmental sciences, and in selected energy technologies. The Laboratory is operated by Brookhaven Science Associates, a not-for-profit research management company, under contract with the U.S. Department of Energy.
