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 »

Ten Billion Light Years Away, A Gang of Supernovae Reveals a Cosmic Secret

November 10, 2004

An international team of astronomers has exposed the largest sample of distant supernovae ever found—150 events, many of which are located about 10 billion light years away from Earth. These events reveal that a particular breed of cosmic explosions, called Type 1a supernovae, occurred five times more frequently when the universe was young than they do today. The paper, authored by a team of American, Israeli and Japanese astronomers, was published in the October 2011 issue of Monthly Notices of the Royal Astronomical Society (MNRAS). Read More »

LBNL Establishes Berkeley Institute for Performance Studies

November 1, 2004

Alan Laub, former director of DOE’s SciDAC program, once said that in the field of high performance computing, “peak performance” was defined as the speed at which “the manufacturer guarantees that you can’t compute faster than that.” Although peak performance figures make for good marketing, they don’t provide much insight into actual performance. To rectify this, for the past eight years Berkeley Lab has been developing new tools and techniques for more accurately… Read More »

Kathy Yelick Named Leader of BIPS, CRD’s Future Technologies Group

November 1, 2004

Kathy Yelick, a professor of computer science at UC Berkeley with a joint appointment in the Computational Research Division, has been named to lead for the newly established Berkeley Institute of Performance Studies (BIPS). She will also be leading CRD’s Future Technologies Group (FTG). Yelick’s appointment, which includes a leave of absence from her teaching position, officially takes effect Jan. 1, 2005. The main goal of Yelick’s research is to develop techniques for obtaining… Read More »

Crystallization in Silico

November 1, 2004

When Francis Crick and James Watson deciphered the structure of DNA in 1953, X-ray crystallography became famous; key to their success was crystallography of DNA done by Rosalind Franklin in the laboratory of Maurice Wilkins. X-ray crystallography has long since become the workhorse for structural studies of big biological molecules, including most of the many thousands of proteins whose structures have been solved in the last half century. Crystallizing biological molecules is… Read More »

LBNL to Highlight Leadership in Computational Science in Presentations, Demos at SC04

October 27, 2004

What kind of scientific breakthroughs can researchers achieve with one million dedicated processor hours on one of the worlds fastest supercomputers? Two million hours? Thanks to a special Department of Energy program, three research groups studying turbulence, astrophysics and chemistry were awarded a total of nearly 5 million hours on the 6,652-processor IBM supercomputer at the National Energy Research Scientific Computing Center (NERSC). Leaders of the three projects, supported under the… Read More »

ESnet to Increase Network Performance, Reliability with Metropolitan Area Networks

October 8, 2004

Responding to the increasingly data-intensive demands of the scientific community, the U.S. Department of Energy’s (DOE) Energy Sciences Network (ESnet) is implementing a new architecture of connected Metropolitan Area Networks (MAN). ESnet, which is managed by DOE’s Lawrence Berkeley National Laboratory, is a high-speed network serving thousands of DOE scientists and collaborators worldwide. A pioneer in providing high-bandwidth, reliable connections, ESnet enables researchers at national… Read More »

Michael Wehner to Analyze Climate Models for International Report on Climate Change

September 1, 2004

Lenny Oliker Michael Wehner, a cli- mate researcher in CRD’s Scientific Computing Group, has received a National Science Foundation grant to analyze the results of three new cli- mate models as a means of determining their predictive quality. Each of the three mod- els will be run to predict both past and future cli- mate change patterns. The results will also be compared with observa- tional climate data to see how the predictions and observations corre- late. “Some features… Read More »
