Madly Mapping the Universe

February 3, 2010

It takes special software to map the universe from noisy data. Berkeley Lab scientists developed a code called MADmap to do just that for the cosmic microwave background, then posted it on the web for other interested sky mappers. Scientists probing the sky with the PACS instrument aboard the Herschel satellite have adapted MADmap to make spectacular images of the infrared universe. Read More »

Tradition of Cosmic Microwave Background Data Analysis Continues with Planck

October 30, 2009

One of Planck's first images is shown as a strip superimposed over a two-dimensional projection of the whole sky as seen in visible light. Image credit: ESA, LFI & HFI Consortia; background optical image: Axel Mellinger More than 95 percent of our universe is made up of mysteriously "dark" materials—approximately 22 percent of it is comprised of invisible dark matter, while another 73 percent is posited to be dark energy, the force that is accelerating universal expansion. Armed with a… Read More »

Berkeley Lab Checkpoint Restart Saves Big Problems

February 9, 2009

A combustion researcher may run hundreds of hours of simulations on a supercomputer in search of the most efficient fuel-air mixture for a flame. But if the system crashes, then all the data from the run might be lost and the researchers forced to start over The new version Berkeley Lab Checkpoint Restart (BCLR) software, released in January 2009, could mean that scientists running extensive calculations will be able to recover from such a crash – if they are running on a Linux cluster. This… Read More »

New Tools for Sharing Wealth of Data to Study Global Resources Issues

January 20, 2009

As they strive to develop effective strategies for guarding water supplies, protecting endangered species and curbing greenhouse gases, environmental scientists are turning to innovative cyber-infrastructures and data-mining tools developed by an ongoing collaboration between researchers at Lawrence Berkeley National Laboratory, Microsoft Research, and the University of California, Berkeley. The Microsoft e-Science program is the primary funder of this project, which is one of numerous ventures… Read More »

Integrated Microbial Genomics Reaches Out to Include Human Microbial Communities

December 1, 2008

We live in a microbial world,” says Nikos Kyrpides of Berkeley Lab’s Genomics Division. “There are millions of organisms in one drop of water and even more in soil. Life on our planet cannot be sustained without the microbes.” However, only a tiny fraction of microbes live as independent species, and even fewer of these can be cultured in the laboratory. The vast majority of bacteria and other microorganisms exist only in the wild, and in complex communities. The collective genome… Read More »

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 »
