ATLAS Software Team Pushes Ahead Led by CRD's David Quarrie

September 11, 2008

GENEVA, Switzerland – When the ATLAS detector goes on line in 2007 as one of two experiments on CERN´s Large Hadron Collider, pairs of protons will be hurtling around the 27-kilometer accelerator ring and smashing into each other at a rate of about one billion collisions per second. This will translate into about 40 terabytes of data, only a small portion of which will be of interest to the team of 1,800 scientists working on the project. Still, the project envisions the need to store and… Read More »

Berkeley Lab Technology for Speeding up Searches of Large Databases Wins R&D 100 Award

July 21, 2008

BERKELEY, Calif.—An indexing technology developed by researchers at Lawrence Berkeley National Laboratory which allows users to search massive datasets up to 40 times faster has been recognized with a 2008 R&D 100 award. The award, presented by R&D Magazine, “provides a mark of excellence known to industry, government, and academia as proof that the product is one of the most innovative ideas of the year.” The awards will be presented at a special ceremony in Chicago in October.

Research on Code Optimization Explores Multicore Computing, Wins Best Paper Award

April 18, 2008

A research paper exploring ways to make a popular scientific analysis code run smoothly on different types of multicore computers won a Best Paper Award at the 2008 IEEE International Parallel and Distributed Processing Symposium (IPDPS) this month. The paper’s lead author and CRD researcher, Samuel Williams, and his collaborators chose the lattice Bolzmann code to explore a broader issue: how to make best use of multicore supercomputers. The multicore trend started recently, and the… Read More »

CRD's Michael Wehner Contributes to National Report on Impacts of Climate Change on Transportation

March 12, 2008

WASHINGTON, D.C. – According to a report issued this week by the National Research Council, every mode of transportation in the U.S. will be affected as the climate changes, with the greatest impact expected to result from flooding of roads, railways, transit systems, and airport runways in coastal areas because of rising sea levels and surges brought on by more intense storms. Though the impacts of climate change will vary by region, it is certain they will be widespread and costly in human… Read More »

Berkeley Lab’s Vern Paxson Honored for Research Characterizing the Internet

February 20, 2008

Vern Paxson, a network researcher at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, has been awarded the Association for Computing Machinery’s Grace Murray Hopper Award for his work in measuring and characterizing the Internet. “His innovative techniques are used to assess new communications concepts, improve network performance, and prevent network intrusion,” according to the ACM. “ They provide both the research community and Internet operators with the… Read More »

Science Journal Features Research On Petascale Enabling Technologies

December 5, 2007

The November 2007 issue of the Cyberinfrastructure Technology Watch (CTWatch) Quarterly included significant contributions – five out of the nine articles – from CRD researchers, who authored papers on code performance, software tools, visualization, scientific data management and data placement solutions for distributed petascale science. The issue featured articles written by dozens of researchers about SciDAC’s Centers for Enabling Technologies. SciDAC (Scientific Discovery through… Read More »

Deconstructing Microbes

November 22, 2007

A metagenome data management and analysis system developed and managed by CRD researchers contributed to a breakthrough research recently published in Nature that probed the genetic materials of microbes in a termite’s gut. Understanding how these microbes convert wood to energy for sustaining a termite’s life would help researchers figure out better ways to convert biomass to biofuels in factories. The microbes exude enzymes that efficiently break down the wood’s cellular structure, but… Read More »

Lab Authors' Paper in Nano Letters Draws Strong Interest

October 15, 2007

A research paper showing how zinc oxide can be manipulated to become a good material for photovoltaic devices was among the most-accessed paper published by Nano Letters in the third quarter. The paper, written by Joshua Schrier, Denis Demchenko and Lin-Wang Wang in CRD’s Scientific Computing Group, laid out the calculations that narrowed the band gap – the energy difference between the top of the valence band and the bottom of the conduction band – of zinc oxide. To effectively absorb… Read More »
