ESnet, Internet2 Extend Agreement for Deploying Next Generation Network to Support DOE Science


ESnet and Internet2 — two of the nation's leading networking organizations dedicated to research — today (July 16) announced a multi-year extension to their agreement to deploy and operate the next generation of the ESnet backbone network. Called ESnet4, the new network created through this partnership is being built as a highly reliable, high capacity nationwide network that will greatly enhance the capabilities of scientists at national laboratories and universities across the country. This long-term partnership, initially announced in August 2006, brings together two advanced networks which have a combined 30 years of experience in providing service to thousands of researchers around the world. The network will be managed by ESnet and operated across Internet2’s backbone infrastructure.

Once complete, the ESnet4 network will utilize several dedicated 10-gigabit-per-second (Gbps) wavelengths on the new Internet2 nationwide infrastructure and will seamlessly scale by one optical wavelength per year for the next four to five years in order to meet the needs of the DOE Office of Science. The Office of Science oversees more than 30 DOE laboratories, 100,000 DOE laboratory scientists, 18,000 researchers from universities, other government agencies and private industry who contribute to many large scale DOE research activities like the experiments at the Large Hadron Collider project at CERN, the Relativistic Heavy Ion Collider at Brookhaven National Lab, among many others.

“This continued investment in ESnet by the Department of Energy’s Office of Science represents a significant contribution to the nation’s research and education infrastructure. In fact, as the single largest supporter of basic research in the physical sciences in the United States, the Office of Science provides research funding for thousands of scientists at universities,” said Bill Johnston, head of the ESnet Department. “By working with Internet2 to increase the reliability and capacity of ESnet, our goal is to advance scientific discovery through access to large-scale scientific resources and improved collaborations.”


David Bailey’s Geocaching Expertise to Be Highlighted in Friday’s View


In his spare time, CRD's Chief Technologist David Bailey likes to put his mathematical skills to work in geocaching, a game that marries technology with outdoor adventures. Read about Bailey and geocaching — and how he won a competition that led him to discover beautiful trails on Mt. Diablo — in The View this Friday. The story also includes tales from NERSC's Associate General Manager Howard Walter, who introduced Bailey to the game nearly a year ago. You can learn about geocaching at http://www.geocaching.com.


John Shalf to Reprise ISC Talk at NERSC Staff Meeting on Wednesday


If you couldn’t make it to the recent SciDAC meeting in Boston or the International Supercomputing Conference in Dresden, you can still hear John Shalf’s talk, which looks at the challenges of programming for parallel computing architecture in the many-core era. Shalf, head of the Science-Driven System Architecture Team at NERSC, will give his talk at the monthly NERSC staff meeting at 1:30 p.m. Wednesday, July 18, at the Oakland Scientific Facility.


Molecular Foundry to Hold Annual User Meeting October 4-5


The Molecular Foundry, a DOE-funded Nanoscale Research Center at LBNL, has scheduled its 2007 User Meeting for October 4-5 in Berkeley. This year’s meeting is being held in conjunction with the annual user meeting of the Advanced Light Source. The Foundry meeting is open to all interested researchers and will include workshops in such areas as nanoscale assemblies, in situ transmission electron microscopy, nanoelectronics, nanophotonics. nanoimprint lithography, polymer science, protein science, cell imaging and nanomagnetism.

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.
