LBNL's Bill Tschudi to Share Expertise in Computer Center Power Efficiency

Bill Tschudi of the Environmental Energy Technologies Division, who is known for his studies of computing center power usage, will be featured as an expert speaker in a Sept. 14 online HPC Expo. Under the theme of “HPC: A World Within Your Reach,” the HPC Expo is a free live broadcast via the Web. The live HPC Expo includes a real-time question and answer session with the expert panel. Registration and more info can be found at http://www.reedbusinessinteractive.com/hpc/default.asp. The forum is produced by Reed Business Publications, including Scientific Computing magazine.

In his talk, entitled “Back to the Future — DC Powering Your Data Center,” Tschudi will discuss how Berkeley Lab is working with over 20 firms in a demonstration to show that large energy savings are possible by eliminating multiple power conversions that typically occur in data centers, resulting in energy efficiency gains. A traditional AC distribution system was set up alongside the new DC distribution system at a Sun Microsystems facility using components loaned by industry partners. Intel and Sun Microsystems modified servers to directly accept high voltage (380V) DC power. Preliminary results are indicating facility-wide energy savings of 10 to 15 percent when considering electrical and HVAC savings, with potential for even greater savings.

Internet2 Issues Call for Participation for Fall Meeting

Internet2, which last week signed an agreement with ESnet to provide the next-generation network serving researchers around the county (read the news release at http://www.es.net/hypertext/esnet.083106-1.html), has issued a call for participation for the Fall 2006 Internet2 Member Meeting, scheduled for December 4–7 in Chicago. The call seeks submissions for track session proposals, demos, posters and side meetings. More information can be found at http://events.internet2.edu/2006/fall-mm/calls.cfm.

Registration Now Open for SC06 Conference

Registration is now open for SC06, the annual conference of high-performance computing, networking, storage and analysis. This year's meeting, with the theme “Powerful Beyond Imagination,” will convene Nov. 11–17 at the Tampa Convention Center in Florida. Online registration information can be found at http://sc06.supercomp.org/registration/attendee.php. To qualify for the advance registration discounts, registration and payment must be received by 5 pm (Eastern time) Sunday, Oct. 15.

This year's technical program includes 26 full and half-day tutorials, 54 technical papers, seven panel discussions, a series of Masterworks sessions, poster presentations and eight workshops. Visionaries and well-known leaders will speak on the state of high-performance computing in the keynote and plenary sessions, as well as participate in lively panel discussions. The exhibition area of the Tampa Convention Center will feature displays by more than 225 industrial and research exhibitors showcasing their latest systems, services and scientific achievements.

SC206 is sponsored by the Institute of Electrical and Electronics Engineers (IEEE) Computer Society and the Association for Computing Machinery's Special Interest Group on Computer Architecture (ACM SIGARCH). For more information, see http://sc06.supercomp.org/.

Job Postings: NERSC User Services Seeks Math, Chemistry Consultants

The NERSC User Services Group currently has job openings for a mathematics consultant and a chemistry consultant. As members of the group, the two consultants will serve as primary points of contact for NERSC users and will be responsible for problem management and consulting; help with user code optimization, debugging and scaling; strategic user project support; documentation; training; and third-party applications and library support.

For the math consultant position, the group is especially interested in candidates with a background in mathematical algorithms for high performance computing, and parallel debugging and scaling experience. The candidate selected will have major responsibilities for helping users select the right software and algorithms for their codes, debug their codes with the TotalView debugger, tune codes for parallel performance, analyze large datasets; for installing, maintaining and documenting math libraries and applications; and for selecting software libraries and packages which meet the needs of NERSC users. More information can be found at http://jobs.lbl.gov/LBNLCareers/details.asp?jid=19395&p=1.

For the chemistry consultant position, the group is interested in candidates with a background in using high performance computing in the area of computational chemistry. The candidate selected will have major responsibilities for helping users select the right chemistry software to meet their scientific needs, for installing, maintaining and documenting chemistry applications, and for selecting chemistry packages which meet the needs of NERSC's chemistry users.

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.
