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 »

CRD’s Helen He Develops Method for Easier Use of Community Climate System Model

April 8, 2006

As part of a comprehensive national project to provide U.S. climate researchers with state-of-the-art modeling capabilities, Yun “Helen” He of CRD’s Scientific Computing Group has developed a “single executable” mode for the Community Climate System Model (CCSM) on NERSC’s IBM SP. CCSM consists of separate programs for modeling atmosphere, ocean, sea ice and land surface and a flux coupler linking the four components. These components are integrated together in original multiple… Read More »

Enron Email Database Proves Easy Pickings for LBNL’s FastBit Search Technology

February 10, 2006

As the trial of former Enron executives gets under way, the extensive email trails left by employees of the Houston energy firm are expected to provide both compelling evidence and entertaining insight. In 2003, as part of an investigation into Enron’s business dealings in California, the Federal Energy Regulatory Commission made public a database containing more than 500,000 emails sent by 151 Enron employees. Subjects ranged from corporate decisions to jokes to personal matters. While the… Read More »

CRD’s pyGlobus Tools Proving Popular

January 10, 2006

CRD’s Distributed Systems Department (DSD), which has led the development of the de facto standard tools for developing Grid Services, applications and portals using the Python programming language, proved a popular draw at the LBNL booth at the SC05 conference in Seattle. Python is a high-level interpreted language that supports a rapid application development cycle. Python’s minimal syntax makes it an ideal language for use by non-computer scientists. It also easily supports binding… Read More »

Former DOE Fellow Wilkening Returns to Berkeley

January 9, 2006

Jon Wilkening, who earned his Ph.D. in 2002 from UC Berkeley working with CRD Math Group Lead James Sethian, has returned to Berkeley as an assistant professor and collaborator with the Math Group. Wilkening accepted a DOE Computational Science Graduate Fellowship in 1997 (while declining an NSF fellowship) and was named a Fred A. Howes Scholar in Computational Science in 2003. As a DOE fellow, he worked as a research assistant in the Math Group from 1997 to 2002. His general research interests… Read More »

CRD’s Keith Beattie Wrapping Up Three Weeks in Antarctica

December 19, 2005

During a time of the year when many people have turned their attention to activities at the North Pole, Keith Beattie of the Distributed Systems Department has been focused on the IceCube project at the South Pole (http://icecube.wisc.edu/). Beattie, a software engineer who has been working on testing the data acquisition software for IceCube, will wrap up his three-week stint at the Antarctica site on Dec. 21 — just in time to spend Christmas on the beach in Australia. Here’s Beattie’s… Read More »
