Q&A with NERSC Director Horst Simon

December 14, 2006

Horst Simon, who has been director of DOE’s National Energy Research Scientific Computing Center (NERSC) since early 1996, announced last month that he was stepping down in order to focus his energy on the two other positions he holds at Lawrence Berkeley National Laboratory. Once a new director for NERSC is hired, Simon will concentrate on his duties as Associate Laboratory Director for Computing Sciences and Computational Research Division (CRD) Director. With the search for a new NERSC… Read More »

Andy Aspden Joins CCSE as Inaugural Seaborg Post-Doc Fellow

December 1, 2006

Armed with a Ph.D in applied mathematics from the University of Cambridge and a thirst to “broaden his horizon,” Andy Aspden has joined Berkeley Lab as part of the inaugural class for the Glenn T. Seaborg Postdoctoral Fellowships.  Aspden will work with John Bell, leader of the Center for Computational Sciences and Engineering in CRD, to expand on his research in fluid dynamics. Aspden, who began his appointment last month, met Bell three and a half years ago when Bell was collaborating… Read More »

Astrophysicist’s Algorithm Leads to Discovery of Super-massive Supernova

September 21, 2006

A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars which until now has been regarded as essentially uniform in all important respects. Supernova SNLS-03D3bb is more than twice as bright as most Type Ia supernovae but has much less kinetic energy, and appears to be 1.5 times as massive as a typical Type Ia. The lead authors of the report, which appeared in the… Read More »

Study Links Human Activities to Warmer Oceans, Stronger Hurricanes

September 15, 2006

New research shows that rising sea surface temperatures (SSTs) in hurricane breeding grounds of the Atlantic and Pacific Oceans are unlikely to be purely natural in origin. These findings, according to a team of researchers including Michael Wehner of CRD’s Scientific Computing Group, complement earlier work that uncovered compelling scientific evidence of a link between warming SSTs and increases in hurricane intensity. Previous studies to understand the causes of SST changes have focused… Read More »

CRD’s Kathy Yelick Named One of HPCwire’s People to Watch in 2006

June 13, 2006

Kathy Yelick, leader of the Future Technologies Group in LBNL’s Computational Research Division, has been named on of 16 “People to Watch” in 2006 by HPCwire, a weekly newsletter covering high performance computing and networking. In addition to her role at the Lab, Yelick is also an associate professor of computer science at UC Berkeley. According to HPCwire, Yelick is worth watching “because she's already a proven dynamo based on her contributions to the development of the Titanium… Read More »

Researchers Analyze Performance, Potential of Cell Processor

May 25, 2006

Though it was designed as the heart of the upcoming Sony PlayStation3 game console, the STI Cell processor has created quite a stir in the computational science community, where the processor’s potential as a building block for high performance computers has been widely discussed and speculated upon. To evaluate Cell’s potential, computer scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory evaluated the processor’s performance in running several… Read More »

New Microbial Metagenome Data Analysis System in Production

May 15, 2006

An experimental metagenomics data management and analysis system co-developed  by the Biological Data Management and Technology Center (BDMTC) at Berkeley Lab with the Genome Biology Program and Microbial Ecology Program at DOE’s Joint Genome Institute and released earlier this year is also already helping produce scientific discoveries. Called IMG/M, the system extends the Integrated Microbial Genomes (IMG) system with the ability to integrate and analyze metagenome data, and has provided… Read More »
