SciDAC Meeting to Showcase LBNL’s Leadership in Projects

May 1, 2005

Since DOE launched its Scientific Discovery through Advanced Computing (SciDAC) program in 2001, scientists at Berkeley Lab have led a number of the projects and provided strong support for many others. When the annual SciDAC meeting is held June 26–30 in San Francisco, LBNL’s con- tributions to the success of the program will be highlighted via invited talks, panel dis- cussions and poster presentations. Here is a rundown of Berkeley Lab contributions to the meeting program. Read More »

LBNL Team Takes Software to the End of the Earth

April 6, 2005

Developing robust, reliable data acquisition software for high-energy physics experiments is always a challenge, but developing such software for an experiment expected to run for up to 15 years while buried in the Antarctic ice poses unique problems. But a team led by Chuck McParland of CRD’s Distributed Scientific Tools Group has risen to the occasion. The first kilometer-long string of 60 detectors recently buried near the South Pole is already recording light pulses as the experiment… Read More »

Berkeley Lab Researchers Lead Parallel Computing Research Center at UC Berkeley

CRD’s Juan Meza Named to National Research Council Panel

March 1, 2005

Juan Meza, head of the High Performance Computing Research Department in CRD, has been appointed as a member of the National Research Council Panel I: Modeling and Simulation, Systems Engineering, and Cost and Risk Analysis, one of 10 panels to review NASA's Capability Roadmaps. The panel will be chaired by Dr. Nancy Leveson, professor of aeronautics and astronautics at the Massachusetts Institute of Technology. The National Research Council is part of the National Academies of Sciences. Read More »

Biological Data Management and Technology Center Marks First Year

March 1, 2005

The Biological Data Management and Technology Center (BDMTC) at Lawrence Berkeley National Laboratory marked its first anniversary with the release of the Integrated Microbial Genomes (IMG) system, a complex biological data management system BDMTC developed in collaboration with the Microbial Genome Analysis Program (MGAP) at the Joint Genome Institute (JGI). As a community resource, IMG integrates JGI’s microbial genome data with publicly available microbial genome data, providing a… Read More »

News About the ACTS Collection

January 1, 2005

In conjunction with demonstrations at the SC2004 conference last November, Osni Marques and Tony Drummond of CRD’s Scientific Computing Group created a matrix of applications that use ACTS tools. Marques and Drummond provide support for the DOE ACTS (Advanced CompuTational Software) Collection, a set of software tools developed by DOE, sometimes in collaboration with other agencies (DARPA, NSF), that make it easier for programmers to write high performance scientific applications… Read More »

Face-to-Face Discussion Helps Fusion Scientists Solve Interface Problem

January 1, 2005

Sometimes, $14 can go a long way. For the price of a train ticket from Manhattan to Princeton, CRD’s Sherry Li was able to meet with scientists at the Princeton Plasma Physics Lab and together they were able to solve problems that were keeping a new fusion code from running fully parallel. Li, a member of the Scientific Computing Group and one of the key developers of the SuperLU library of solvers, had been consulting with Steve Jardin’s group at PPPL for several months as the… Read More »

LBNL Speaker Series in Washington to Feature CRD Expertise

January 1, 2005

Beginning in February, scientists from CRD will launch a series of presentations at Berkeley Lab’s project office in Washington, D.C. The goal of the series is to better inform the Washington research community about the achievements and expertise of LNBL staff. The LBNL office is located at 901 D Street, SW, Suite 950. The office is in the Aerospace Center, across D Street from L’Enfant Plaza. Directions to the office can be found at… Read More »

FastBit: An Efficient Indexing Technology for Billions of Objects

January 1, 2005

Three members of the Scientific Data Management Group - John Wu, Arie Shoshani and Ekow Otoo - have been granted a patent for their "Word Aligned Bitmap Compression Method and Data Structure." This technology is currently used in a software called FastBit to compress bitmap indices. When answering a user query, FastBit is often 10 times as fast the searching method used by one of the leading commercial database management systems. One of the first applications that employs FastBit is… Read More »

LBNL’s DataMover Reaches Milestone with Automated Transfer of 18,000 Files in a Single Request

November 30, 2004

Amidst the hype and hoopla at the recent SC2004 conference in Pittsburgh, Lawrence Berkeley National Laboratory’s Scientific Data Management Research Group demonstrated the robustness of the group’s DataMover by putting the application through its workaday paces. In doing so, the group reached a milestone when, with a single request, 17,870 data files were moved seamlessly from Brookhaven National Lab in New York to LBNL, both of which are operated by the U.S. Department of Energy. What… Read More »
