HPCwire Article Digs into Details of New NERSC System

Following the June 27 announcement that NERSC has ordered a two-petaflop "Cascade" supercomputer, Cray's next-generation HPC platform, HPCwire editor Michael Feldman contacted Acting NERSC Division Director Kathy Yelick and NERSC Systems Department Head Jeff Broughton for more information on the decision. The system includes about 6.5 petabytes of the Cray's Sonexion storage and the contract covers both hardware and services, which will extend over multiple years. Installation is scheduled for 2013.

CRD's Michael Wehner Quoted in Article on Extreme Weather

Michael Wehner of CRD's Scientific Computing Group was one of eight climate scientists contacted by Leo Hickman of the Guardian newspaper in the UK for a blog about the relationship between extreme weather conditions and global climate change. Wehner frames his answer by saying "Whenever an extreme weather event occurs, it is natural for the public to ask, 'Is this event a result of global warming? 'This is not the quite the correct question to ask...The more relevant question to ask is 'How has the risk of this event changed because of climate change?' " Read the full story.

ESnet Staff to Share Networking Expertise at Summer Joint Techs Meeting

Twice a year, staff from ESnet and Internet2, two of the leading research and education networks, meet to exchange information and experiences on topics of mutual interest. The meetings, known at the Joint Techs, also draw an international crowd of networking experts. The Summer 2012 meeting will be held July 15-19 at Stanford University. ESnet staff will give several presentations which will be streamed live:

  • Jon Dugan will discuss "The MyESnet Portal: Making the Network Visible" (4:30 p.m. Monday, July 16).
  • Inder Monga will discuss " SDN Use by National Labs." (9:30 a.m. Tuesday, July 17).
  • Greg Bell will present and "ESnet Update" (8:30 a.m. Wednesday, July 18).

For information on the streaming presentations, go to the meeting agenda and click on the Netcast icons.

Bell will also host a Birds-of-a-Feather session on "Quantifying Success in R&E Networking" on Tuesday, July 17. On Sunday, July 15, Michael Sinatra will present a DNSSEC Tutorial: Signing, Validating, and Troubleshooting. The half-day session will provide an overall understanding of DNSSEC (DNS Security Extensions).

Primary focus areas of the meeting include Software Defined Networking (SDN), of which ESnet's Inder Monga is co-chair; and Integration of Services across Multiple Networks, co-chaired by ESnet's Evangelos Chaniotakas. Michael Sinatra of ESnet is co-chair of the IPv6 Area of Continuing Interest.

The Joint Techs meeting will be followed by a day-and-a-half meeting of the ESnet Coordinating Committee (ESCC). The ESCC is the technical forum that establishes community practices that govern the smooth operation of the ESnet-Labs/sites joint networking endeavor.

NERSC, ESnet Provide Key Resources to Search for Higgs Boson

The ATLAS and CMS experiments at CERN recently presented their latest results in the search for the long-sought Higgs boson. Both experiments see strong indications for the presence of a new particle, which could be the Higgs boson, in the mass region around 126 gigaelectronvolts (GeV). The experiments found hints of the new particle by analyzing trillions of proton-proton collisions from the Large Hadron Collider (LHC) in 2011 and 2012. The Standard Model of particle physics predicts that a Higgs boson would decay into different particles—which the LHC experiments then detect.

Analysis and detector simulations for the ATLAS collaboration are conducted on the PDSF system at NERSC. ESnet provides key network connectivity allowing scientists to share, access and analyze the data. For more information about the discovery, go to http://public.web.cern.ch/public/.

Call for Proposals for Joint US-Asian R&E Networks Conference

The Winter 2013 technical meeting between the Joint Techs meeting and the Asia Pacific Advanced Network (APAN) has issued a call for proposals. The meeting will be held January 13-16, 2013, at the University of Hawaii and include a full day of tutorials and workshops.

The following topics have been identified as being of particular interest, although proposals in other areas relating to research and education networking are also invited:

  • Network Research and Emerging Technologies (including Software Defined Networking/OpenFlow; Security in R&E Networking; Network Performance and Measurement; and "Future Internet")
  • Network Architecture and Operations (including 100G implementation experiences; IPv6; Network performance and utilization; R&E network infrastructure and connectivity updates; and Pacific Islands connectivity)
  • R&E Network Applications (including Astronomy; Ocean observatories; Climate and environment; Disaster management; e-Medicine and e-Health; e-Culture and performance; Global collaboration; and e-Learning)

ESnet's Inder Monga is a member of the program committee.

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.
