This month, Research, Computing and Engineering (RCE) hosts Brock Palen and Jeff Squyres chatted with Paul Hargrove of CRD's Future Technologies Group (FTG) about the Berkeley Lab Checkpoint Restart project, for checkpointing, restartaring and migrating HPC applications. RCE is a podcast that targets topics relevant to the HPC and research computing communities.

An innovative new sky survey, called the Palomar Transient Factory (PTF), will utilize the unique tools and services offered by NERSC to expose relatively rare and fleeting cosmic events, like supernovae. During the commissioning phase alone, the survey has already uncovered more than 40 supernovae and astronomers expect to discover thousands more per year. More>

CRD climate researcher Michael Wehner developed projections of future climate change for a report from the U.S. Global Change Research Program. The precipitation map shown is one of the projections developed by Wehner. It shows, among other things, a substantial reduction in springtime rains in California, and summertime rains in the Pacific Northwest. More>

As computational scientists are confronted with increasingly massive datasets, one of the biggest challenges is having the right tools to gain insight from the data. Recently a team of DOE researchers found that VisIt may be up to the challenge. They ran VisIt using 8,000 to 32,000 processing cores to tackle datasets ranging from 500 billion to 2 trillion zones More>
Although it has been a network protocol standard for more than 10 years, IPv6 (Internet Protocol version 6) has only been minimally implemented by the networking community. But that could change now that the U.S. Department of Energy’s Energy Sciences Network (ESnet) has deployed a production IPv6 management system across its entire network. More>
Five fellows from the Department of Energy's Computational Science Graduate Fellowship (CSGF) are honing their computational science skills at the Lawrence Berkeley National Laboratory (Berkeley Lab) this summer. The five students will assist researchers in the Lab's Computational Research Division (CRD), Life Sciences Division, and Molecular Foundry, where they will contribute to groundbreaking research that will help engineers design better medical imaging tools, airplanes, and tailor treatments for cancer patients.

NERSC Director Kathy Yelick presented the first keynote, Ten Ways to Waste a Parallel Computer, at the 2009 International Symposium on Computer Architecture (ISCA) on June 22 in Austin, Tex. More>
Computers can construct and display mirror images of increasingly detailed pieces of nature in action, generating visual understanding that can rival observation. That's why the Department of Energy's Scientific Discovery through Advanced Computing (SciDAC) program is supporting the Visualization and Analytics Center for Enabling Technologies (VACET), which is co-directed by Wes Bethel, head of the Berkeley Lab's Visualization and Analytics Group, and Chris Johnson, director of the Scientific Computing and Imaging (SCI) Institute at the University of Utah.

Despite decades of analyzing satellite and simulation data, scientists have barely begun to predict clouds' behavior or to understand their major influence on the atmosphere and global climate. Many questions remain and David Randall, an atmospheric scientist at Colorado State University, leads a team seeking answers to those questions and others with a new global cloud-resolving model (GCRM) that will use computers to portray Earth's atmosphere in 10-second snapshots. The project is supported by the Department of Energy's Scientific Discovery through Advanced Computing (SciDAC) program, and most of the development work was done at NERSC. More>
