NetLogger Helps Supernova Factory Improve Data Analysis
The Nearby Supernova Factory (SNfactory) project, established at Berkeley Lab in 2002, aims to dramatically increase the discovery of nearby Type 1a supernovae by applying assembly-line efficiencies to the collection, analysis and retrieval of large amounts of astronomical data. To date, the program has resulted in the discovery of about 150 Type 1a supernovae – about three times the entire number reported before the project was started. Type Ia supernovae are important celestial bodies… Read More »

LBNL Team Takes Software to the End of the Earth
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 »

Face-to-Face Discussion Helps Fusion Scientists Solve Interface Problem
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 fusion… Read More »
LBNL’s DataMover Reaches Milestone with Automated Transfer of 18K Files
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 »
Crystallization in Silico
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 tricky, however. Read More »
The spirit of Lawrence’s Lab lives at CERN
GENEVA, Switzerland ‑ Six thousand miles east of Berkeley, in the rolling countryside of the Swiss-French border, the spirit of Ernest Lawrence is alive and well. Berkeley Lab’s founder is noted for many contributions to scientific knowledge, but two of his best-known ideas are the invention of the cyclotron and the idea of bringing together groups of people with a diversity of knowledge and expertise to take on the biggest scientific challenges. At CERN, the European Center for Nuclear… Read More »
Anatomy of a Web(bed) Legend
In the wild, a frog may live to 10 years, assuming it survives tadpolehood and doesn’t get eaten by a bird or a fish or some other creature. On the Web, though, a virtual frog named “Fluffy” has easily notched its tenth year despite millions of dissections. Launched in June 1994, by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, the Virtual Frog Dissection Kit Web site allows users to virtually dissect a frog without all that smelly formaldehyde of high school… Read More »

An Algorithm for the Ages
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 »
