NERSC Users' Group Meeting and Training Set for February 1–3

Registration is open for the NERSC Users' Group Meeting and HPC training on Feb. 1–3, 2012. The meeting will be held at NERSC's Oakland Scientific Facility. All three days will be available as a WebEx web meeting for remote participation. All NERSC users are invited to attend all three days.

Wednesday and Thursday, Feb. 1 and 2, are day-long training events. Wednesday's training is targeted at new NERSC users, while Thursday's session will cover more advanced topics. The training agenda is available here. The NUG business meeting will be held on Friday, Feb. 3. There is no registration fee for NUG 2012.

Symposium to Honor Eli Yablonovitch on January 27 at UC Berkeley

“Photons, Electrons, Bands: A Symposium on the Diversity of Opto-Electronics” will be held Friday, January 27, in Banatao Auditorium, Sutardja Dai Hall at UC Berkeley, in honor of Professor Eli Yablonovitch on his 65th birthday. You are cordially invited to attend an exciting day of talks on:

  • Solar Energy
  • Nano-Opto-Electronics
  • Photonic Crystals
  • Metal Optics
  • Quantum Information

Please see the advance program here. Admission is free, but registration is required. To attend, please register here by January 22.

Professor Yablonovitch is Director of the NSF Center for Energy Efficient Electronics Science (E3S). In his photovoltaic research, he introduced the 4n2 light-trapping factor that is used commercially in almost all high performance solar cells. He also introduced the idea that strained semiconductor lasers could have superior performance due to reduced valence band (hole) effective mass. Today, almost all semiconductor lasers use this concept, including telecommunications lasers, DVD players, and laser pointers. Professor Yablonovitch is regarded as one of the fathers of the photonic bandgap concept, and coined the term “photonic crystal.”

Link of the Week: Mapping the (11) Divisions in American Society

Colin Woodard suggests that we’ve been vastly oversimplifying things by talking about America’s internal divisions between red states and blue states, between “the coasts” and the “heartland,” between the urban and the rural or even the North, South, Midwest and West. Instead, the veteran journalist slices North America into eleven culturally distinct regions that look something like a continentally gerrymandered map gone wild.

Until more Americans grasp what this map implies, he believes, we’ll continue to have a hard time forging national consensus.

Woodard floats this thesis in a new book, American Nations: A History of the Eleven Rival Regional Cultures of North America, that offers novel perspective on the current U.S. predicament of culture wars mixed with political paralysis mixed with economic disarray. His assessment recalls another region with complicated geography: the Balkans. Read more.

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.
