ESnet Increases Bandwidth to Brookhaven, Oak Ridge National Labs


Network connections provided by ESnet have been upgraded to two DOE labs, Brookhaven in New York and Oak Ridge in Tennessee. Under the ESnet contract, Qwest Communications International Inc. increased ESnet's bandwidth by providing an OC-48 (2.56 Gbps) local access connection to the Brookhaven National Laboratory in Upton, NY, and to the Oak Ridge National Laboratory in Oak Ridge, Tenn. Funded primarily by the DOE Office of Science, ESnet is managed by the ESnet department within ITSD. ESnet operates a backbone network connecting more than 35 DOE research sites.

"Scientists around the world are increasingly dependent on reliable, high-bandwidth connections, whether they are using network resources to collaborate or are participating in experiments yielding terabytes of data," said Bill Johnston, ESnet manager at Berkeley Lab. "This upgraded bandwidth, along with our proven reliability, is critical to advancing scientific research within the Department of Energy community and with its university and international research and education collaborations."

The upgrades enable scientists to take better advantage of the 2.5G/10G ESnet backbone. ESnet currently has a six-node optical fiber backbone network, much of which was upgraded in 2003 to 10 Gigabits per second through Qwest's Qwave services, a suite of fully managed, all-optical, high-capacity private line services. Qwest also is providing local access to the Oak Ridge facility.


Next Ethics Awareness Training Session to Be Held November 17


As a follow up to a talk last year, Associate Lab Director Horst Simon has commissioned an Ethics and Values committee to formulate a code of conduct for the organization. The committee is presenting a summary of their findings at two division meetings in October and November. Five areas will be covered: (1) scientific and professional integrity; (2) responsibility to the Lab; (3) working with colleagues; (4) customer service; and (5) security.

Every CS employee must attend one of the two presentations. The first was held Oct. 4 in conjunction with the ITSD all-hands meetings. The second presentation will be given as part of the November NERSC/CRD Technical Meeting starting at 2 p.m. Wednesday, Nov. 17. All Computing Sciences staff may attend the meeting, which will be held in the Bldg. 50 auditorium.


CRD's Scientific Computing Group Has Post-Doc Position in Nanoscience


The Scientific Computing Group in the Computational Research Division has one or two immediate openings for postdoctoral fellows in nanoscale electronic structure calculations. These positions are funded by DOE nanoscience initiatives. Close collaboration with experimental groups at LBNL and UC Berkeley is expected.

The successful candidate(s) will work with Lin-Wang Wang in electronic structure calculations of various nanostructures (colloidal quantum dots, conjugated polymers, electronic levels and transports), and methodology developments for large-scale nanosystem electronic structure calculations (e.g., charge patching methods, polarizations, impurities and transports). Essential qualifications include a Ph.D. degree in physics or related fields, as well as experience in electronic structure calculations and programming skills. This is a one-year term position with the possibility of renewal for up to three years. For more information, go to http://www.lbl.gov/CS/Careers/OpenPositions/CR17572.html.


Read This If You Want to Read Email after Nov. 1 and Don't Use Lab-Issue Mozilla


As part of the Computer Protection Program's ongoing efforts to protect Lab users against escalating security threats, beginning Tuesday, November 2, all connections to the Lab's central mail server, imap4.lbl.gov, must be encrypted using secure sockets layer (ssl). This will not affect the majority of users. Additionally, it impacts only receiving, not sending, email.

Users who do not use the Lab-supplied version of Mozilla (available at http://www.lbl.gov/download) are likely to need to make a small configuration change in their mail client. Visit http://www.lbl.gov/imapssl/ to determine whether your mail client needs this change and how to make this change if necessary. For assistance, call the Help Desk at X4357 or send email to help@lbl.gov.


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.
