Envisioning the Grid

January 29, 2003

At last year's SC2002 conference in Baltimore, Berkeley Lab racked up its third straight win in supercomputing's annual Bandwidth Challenge with a data-gobbling visualization of colliding black holes. When it comes to remote scientific visualization, says Wes Bethel with a smile, "we're the kings." Now Bethel and John Shalf of the Computational Research Division's Visualization Group have followed up their SC2002 success by writing a good chunk — including the guest editorial — of the… Read More »

Reorganization Leads to New CRD, NERSC Center Divisions

June 26, 2002

The Laboratory’s National Energy Research Scientific Computing (NERSC) Division is being reorganized into two new divisions – the NERSC Center Division and the Computational Research Division, Lab Director Charles Shank announced earlier this month. The goal of the reorganization, which was outlined in the NERSC five-year strategic proposal written and submitted to DOE last year, is to heighten the visibility of the NERSC Center as a national user facility supported by DOE’s Office of… Read More »

Chorin Awarded Prestigious “University Professor” Honor By UC Regents

February 14, 2002

Dr. Alexandre Chorin, a founding member of Berkeley Lab’s Mathematics Department and a professor of Mathematics at UC Berkeley, has been honored with the title of University Professor by the Regents of the University of California. The title of University Professor is reserved for scholars of international distinction who are also recognized and respected as exceptional teachers. It is a way to share their talents throughout the UC system for at least five years and no more than ten. Read More »

An Algorithm for the Ages

January 20, 2000

Australian researchers have done the impossible—they’ve found the sixty-trillionth binary digit of Pi-squared! The calculation would have taken a single computer processor unit (CPU) 1,500 years to calculate, but scientists from IBM and the University of Newcastle managed to complete this work in just a few months on IBM’s BlueGene/P supercomputer, which is designed to run continuously at 1petaflop/s—that’s one quadrillion calculations per second! Their work was based on a… Read More »

Algorithm for the Ages: Better Way to Find Integer Relations

January 20, 2000

  Among the top ten "Algorithms of the Century" announced in the January/February, 2000, issue of Computing in Science and Engineering magazine is the integer-relation algorithm dubbed PSLQ, discovered by mathematician and sculptor Helaman Ferguson of Maryland's Center for Computing Sciences, and implemented in practical computer software by David Bailey, chief technologist of the National Energy Research Scientific Computing Center (NERSC) at the Department of Energy's Lawrence Berkeley… Read More »

BOOMERanG Analysis Finds Flat Universe

December 12, 1999

  Newly released data from the 1997 North American test flight of BOOMERanG, which mapped anisotropies in the cosmic microwave background radiation (CMB) in a narrow strip of sky, show a pronounced peak in the CMB "power spectrum" at an angular scale of about one degree, strong evidence that the universe is flat. Analyzed at the Department of Energy's National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory, the new data also suggest the existence… Read More »

CRD’s Costin Iancu to Present at NITRD Workshop on Software Sustainability

Costin Iancu of CRD’s Computer Languages and Systems Software (CLaSS) Group will give a short talk and present a poster at the Oct. 15-16 workshop on Computational Science & Engineering Software Sustainability and Productivity Challenges. An inter-agency workshop sponsored by the Networking and Information Technology Research and Development (NITRD), CSESSP Challenges will identify the unique issues around software productivity and sustainability faced by the NITRD computational science… Read More »
