LLNL's David L. Brown Named New Director of CRD

David Brown, who is currently the Deputy Associate Director for Science and Technology in Lawrence Livermore's Computation Directorate, has been named as the new director for the Computational Research Division (CRD). Brown will join Berkeley Lab on August 30.

In his new position, Brown will provide scientific leadership for CRD research and development programs in mathematics, computer science and computational science, and serve as chief spokesperson for CRD in interactions with external agencies, including the Department of Energy. Read more.

CS Staff Share Python Expertise at SciPy 2011

SciPy 2011, the Python for Scientific Computing Conference, is being held this week (July 11–16) in Austin, Texas. By providing a forum for developers to share their Python expertise with the wider commercial, academic, and research communities, this conference fosters collaboration and facilitates the sharing of software components, techniques, and a vision for high level language use in scientific computing. Attendees have the opportunity to review the available tools and how they apply to specific problems.

Presentations by Computing Sciences staff include:

  • Shoaib Kamil: Bringing Parallel Performance to Python with Domain-Specific Selective Embedded Just-in-Time Specialization
  • Shreyas Cholia and Annette Greiner: RESTful APIs for Scientific Computing in Django

HPC in the Geosciences Workshop Next Week at CITRIS

The Society of Exploration Geophysicists and the Center for Information Technology Research in the Interest of Society (CITRIS) are presenting a workshop on High Performance Computing in the Geosciences next week, July 18–21, in the Banatao Auditorium of Sutardja Dai Hall at UC Berkeley.

Compute intensive imaging paradigms such as reverse time migration, iterative and interactive model building, and waveform inversion make high performance computing (HPC) more vital than ever to the oil and gas industry mission. In addition to imaging, HPC is critical for everything from timely modeling and simulation of large-scale physical systems, to processing, analysis and interpretation and visualization of huge seismic data volumes. Some applications, such as waveform inversion and true wave equation MVA, were previously thought to be computationally impossible or impractical but are now making inroads into routine commercial applications.

This workshop will focus on implementations of these geophysical applications, in addition to the application in reservoir, petroleum engineering and geology presented by practitioners at the cutting edge of the field. Topics will include recent advances in HPC, as well as challenges due to the end of Moore's Law and its impact on the oil and gas industry, and tools such as parallel visual analytics and routines that can be coupled with data analysis and simulations run on new HPC architectures or so-called integrated data analysis, visualization, simulation, computing environments that provide an end-to-end solution for analysis and visualization of scientific data and simulation results.

Speakers from Computing Sciences include:

  • Katie Antypas, David Skinner, Tony Drummond, and Masoud Nikravesh: LBNL-DOE-HPC Hardware and Software Resources (NERSC, ACTS, SciDAC)
  • Wes Bethel and Hank Childs: Challenges and Solutions for Visual Data Analysis on Current and Emerging HPC Platforms
  • David Donofrio: GreenWave: An Energy-Efficient Architecture for Seismic Imaging
  • Keith Jackson: Cloud Computing for Data Intensive Science
  • Inder Monga: Service-Oriented Networks: Bridge between Campus and Mega-Cloud Centers

Link of the Week: CitySandbox

A collaboration of art, engineering, and social sciences at the University of California, CitySandbox has gone live for beta testing and feedback. This new website helps Berkeley residents ask questions about specific places in their neighborhoods and aims to be a tool for individuals to make their city a better place. Neighbors can discuss their concerns with other neighbors, identify priorities, form collective opinions, and take action towards common goals. They can find out who else is interested in their questions and how a group can address them. Through a system of voting and discussion, all community members can weigh in, make their voices heard, and build their reputations as active citizens.

CitySandbox is a project of the Social App Lab at CITRIS. The Lab is founded and directed by Professors James Holston (Anthropology) and Greg Niemeyer (Art Practice and New Media Studies) and focuses on the potential of cell phones and other locative media to harness the participatory energies of game-play to address social issues.

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 7,000-plus 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 Department of Energy 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.
