CRD’s Julian Borrill Invited to Join NASA Team for Planning Future Mission

Julian Borrill, an astrophysicist in the Scientific Computing Group, has been invited to join NASA's Primordial Polarization Program Definition Team (PPPDT), charged with planning the cosmic microwave background radiation (CMB) polarization mission after the upcoming Planck satellite mission.

The team includes 13 experimentalists (including the PIs of two other major CMB missions, WMAP and US Planck), one theorist and one data analyst.

“The presence of even one data analyst is an enormous step forward, and reflects the growing recognition of the need to include data analysis in CMB mission planning and the critical role that NERSC and LBNL play in the field,” Borrill said.

Borrill, along with Chris Cantalupo and Ted Kisner, has been doing extensive simulations based on the amount of data expected to be gathered over the course of a year by the 74 detectors on Planck satellite.

Members of the PPPDT will work in collaboration with NASA Headquarters, the National Science Foundation (NSF), DOE, NASA Field Center scientists and engineers and the astronomical community to provide input during conceptual development of a CMB polarization mission. The PPPDT will help provide the astronomy community input on questions relating to the science capabilities of a potential mission and will help disseminate information about the mission concept to the community. See http://groups.physics.umn.edu/cosmology/PPPDT/ for more details.


ESnet News Is Back

ESnet News, a quarterly that highlights the development work and services by ESnet staff, is back. The July-September issue, published today, provides an update of the ESnet4 project and efforts to deploy a bandwidth provisioning system and a set of network monitoring software. Read about the two recent network requirement workshops ESnet staff organized for scientists in the Basic Energy Sciences and Biological and Environmental Research programs within the Office of Science. The newsletter will be available this afternoon at http://www.es.net/hypertext/whats-new.html.


Don’t Forget Computing Sciences’ Sept. 20 Pizza & Grill Party for All Staff

All CRD and NERSC staff are invited to attend a pizza and grill party from 4-6 p.m. Thursday, Sept. 20, at the Oakland Scientific Facility (OSF, Building 943) parking lot. Pizza (meat and vegetarian varieties) from Zachary’s and a variety of grilled sausages will be provided.

OSF is located at 415 Thomas L. Berkley Way (also known as the 20th St.), Oakland (Franklin is the cross street). No parking is available at the building, but a variety of public garages can be found within close walking distance. Please see http://www.douglasparking.com/Kaiser_Center.73.0.html for information on nearby lots. OSF is located right next to the 19th Street BART station. Area maps and other info can be found at https://www.nersc.gov/about/visitor.php.


CITRIS Presents Talk on “Innovation Goes Public” Today

The Center for Information Technology Research in the Interest of Society (CITRIS) will present a talk on “Innovation Goes Public” from 4:00 to 5:00 p.m. today in room 306 at Soda Hall on the UC Berkeley campus. The talk will be given by Bruce Perens, vice president at Sourcelabs and co-founder of the Open Source initiative. As always, these talks are free, open to the public and broadcast live online at mms://media.citris.berkeley.edu/webcast.

Here is the abstract:

“Open Source provides much of the software infrastructure for many of the world's largest companies and organizations: Merrill Lynch, Google, Pixar, Amazon, the City of New York, and probably you--although you might not know it. Innovative products like Linux, Firefox, and Apache are the market-leaders in their sectors, but there are tens of thousands of Open Source programs, used for just about everything. But the economics of Open Source are non-intuitive: how can you make money by giving software away? Why did IBM de-emphasize AIX, after spending billions, in favor of Linux, the product of a loose collaboration of programmers that it can never control? How can the world's greatest city trust Open Source to help manage its jails?

“Perens will show how Open Source is often the most effective strategy for creating and utilizing new innovation. He will explain the economics of Open Source and how it works for profit-generating companies. His talk will be clear to beginners yet informative even for Open Source pros.”



About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 6,000 scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are DOE Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
