On ABC7, Eli Dart Discusses Impact of IPv6 on Businesses

In an interview with Richard Hart of KGO TV, ESnet network engineer Eli Dart discussed why Internet Protocol version 6 (IPv6) is important, what it means to businesses, and what will happen if companies lag in implementing it. The interview aired during this morning’s business report and will be repeated during tonight’s (June 4) 6:00 pm news on ABC7. Later the video will be posted on the Drive to Discover web page.

Hemant Shukla Leads GPU Tutorial at IEEE Real-Time Conference

Berkeley Lab is hosting the IEEE Nuclear and Plasma Sciences Society’s 2012 Real-Time Conference (RT2012) from June 11 to 15 at the Hotel Shattuck Plaza in downtown Berkeley. RT2012 will be a multidisciplinary conference devoted to the latest developments on real-time techniques in the fields of plasma and nuclear fusion, particle physics, nuclear physics and astrophysics, space science, accelerators, medical physics, nuclear power instrumentation and other radiation instrumentation.

On Sunday, June 10, Hemant Shukla of the Advanced Technologies Group in CRD will lead an all-day pre-conference tutorial on “Data Analysis with GPU,” which will present programming models that take advantage of graphics processing units, as well as tools and techniques for optimizing performance. CRD researchers Jose Fiestas, Hari Krishnan, Richard Martin, and Didem Unat will give presentations at the tutorial.

David Skinner to Discuss Public Data Bases for Science

Progress on Statistical Issues in Searches, a conference involving statistical issues in astrophysics, particle physics, and photon science, is being held this week, June 4–6, at SLAC National Accelerator Laboratory in Menlo Park. David Skinner of NERSC will give a short talk and participate in a panel session, “The Development and Use of Public Data Bases: It’s Complicated!” He will relate why the national labs are well suited to curate and add value to large scientific datasets, the advantages of gateway approaches seen thus far, and the need to move the statistics (analytics in HPC jargon) to the data.

Skunk Alert Around Building 50: Keep Your Distance

SkunkSkunks have been seen around the Building 50 Auditorium outside stairs and the 50–50B fourth floor connecting walkway. If threatened, skunks can spray a liquid with a strong, foul odor. If a skunk lifts its tail, it may be about to spray. Leave the area immediately if a skunk lifts its tail or approaches you. For your safety, do not approach or feed any wild animal.

The Lab’s integrated pest management vendor has placed a repellent odor material in the areas around B50. This is intended to encourage the skunks to relocate, without harming them.

Link of the Week: Your Name in Galaxies

Ever wanted to see your name in lights? Well, lights don’t get much bigger than galaxies! Now, using the My Galaxies website, you can write your name or any other message in actual photos of galaxies from the Sloan Digital Sky Survey.

It all started when the Galaxy Zoo project asked members of the public, the Zooites, to look through nearly one million galaxies to make a catalogue of their shapes for scientific use. All of these objects are special, in their own ways, but some are particularly weird and wonderful. The Zooites started collecting these peculiar galaxies on the Galaxy Zoo Forum, the most beautifully simple, the most spectacular, the most messy, even those that happen to look like animals and, here we get to the point, letters of the alphabet!

Then Steven Bamford, an astronomer at the University of Nottingham, UK, wrote a computer program that automatically selects galaxy images for any combination of letters, which is the engine behind the My Galaxies website. With a colleague, Bamford wrote an April Fool’s Day paper titled “Galaxy Zoo: an unusual new class of galaxy cluster,” which concluded:

Thanks to the visual inspection of SDSS images afforded by the Galaxy Zoo project, we have identified a new class of galaxy clusters which possess a number of unusual properties. These clusters are unusually elongated, possess young and highly dynamic galaxy populations, and most unexpectedly, present neatly typeset, left-justified, messages written in the English language. One interpretation for the existence of these galaxy clusters is as conclusive evidence for intelligent life elsewhere in the universe. Conversely, however, they could indicate that many phenomena usually attributed to intelligent life on Earth actually occur spontaneously, without any thought necessarily being involved at all.

The Galaxy Zoo has expanded beyond galaxies to supernovae and Milky Way objects as well, and Peter Nugent and the Palomar Transient Factory team actually upload their supernova data for citizen scientists to classify at the Galaxy Zoo Supernovae website. Unfortunately, supernovae don’t have the entertainment value of galaxies.

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.
