The rapid retreat of Antarctica’s Pine Island Glacier (PIG)—the single largest contributor to sea level rise in Antarctica—has perhaps reached a point of no return. Unless the region experiences much colder conditions the retreat will continue, say three international modeling teams writing in Nature Climate Change. They came to this conclusion after running a number of simulations to model the glacier’s behavior. To do this work, the researchers relied on three different ice-flow models including BISICLES, which was developed by a collaboration that included Berkeley Lab computational scientists. More>

Just six years from now, Japan-based RIKEN says it will complete a supercomputer finally capable of mongo-calculative deftness on par with what some believe to be the processing oomph of a single human brain. The company says it was selected by Japan’s Ministry of Education, Culture, Sports, Science and Technology to design an exascale supercomputer, and that this nascent exa-behemoth will begin working in 2020. But some think 2020′s too soon. Berkeley Lab’s Horst Simon is betting that we won’t reach exascale-computing power by 2020. More>
Scientific American named the recent IceCube observation of high-energy cosmic neutrinos one of its top 10 science stories of the year, while Physical Review listed the discovery as one of its highlights of the year. Scientific American also included a cover story (pictured) on creating a materials database written by EETD’s Kristin Persson, who touched on the Lab’s efforts in this field.
When scientists from around the world visit Dula Parkinson’s microtomography beamline at the Advanced Light Source, they all want the same thing: amazing, scientifically illuminating, micron-scale X-ray views of matter, whether a fiber-reinforced ceramic composite, an energy-rich shale, or a dinosaur bone fragment. Unfortunately, many of them have left lately with something else: debilitating data overload. More>
The final steel girder of the Computational Research and Theory facility was hoisted into place today in a “topping off” ceremony. As tradition dictates, the beam was decorated with an evergreen and American flag and signed by both the builders and some of the eventual occupants, including Kathy Yelick, Associate Lab Director for Computing Sciences. When construction is complete in early 2015, the CRT facility will house all three divisions of Berkeley Lab’s Computing Sciences, as well as NERSC’s supercomputers in a state-of-the-art data center.

For Aseel Honein, an architect, teacher and design activist from Lebanon, spending a month collaborating with scientists at Berkeley Lab was a dream come true. She got the opportunity to do so through the TechWomen 2013 program, which brought 76 women from 16 Middle Eastern and African countries to the U.S. in October for a five-week professional mentoring program. Five of these emerging leaders were hosted by colleagues from the Lab who worked closely with them on projects related to their burgeoning careers. More>
[Wired] Alex Ramirez wants to build a supercomputer that’s six times as powerful as Tianhe-2, the Chinese machine that’s ranked as the world’s most powerful. That’s an incredibly ambitious goal, but here’s the surprising part: He wants to build it using the sort of chips you typically find in mobile phones and tablets. He wants to use ARM processors. Whatever chips are used, many countries are working to build exascale machines, but in the U.S., budget cuts have tapered funding for these projects. Since 2010, the Lab’s funding has been flat or downward, said Deputy Director Horst Simon. More>
When the SC13 conference opens Nov. 17 in Denver, the facilities and capabilities of DOE 15 national labs (including Berkeley Lab) will be highlighted in one booth for the first time. The booth program features presentations by HPC experts, electronic posters, demonstrations, roundtable discussions and a 3D display showing simulations and modeling. Kathy Yelick and Greg Bell are among the 14 featured speakers giving talks in the booth. ESnet will be demonstrating the MyESnet portal and hosting a discussion of the Science DMZ. Saul Perlmutter will answer questions about supernovae and supercomputers. More>
Computing Sciences is launching a Distinguished Lecturer Series, with the first talk to be given by Cleve Moler at 2 p.m. Wednesday, Nov. 13, in the Building 50 Auditorium. Moler is the creator of MATLAB and a cofounder of MathWorks, where he is currently chairman and chief mathematician of the company. In his talk, Moler will show how MATLAB has evolved over more than 30 years from a simple matrix calculator to a powerful technical computing environment. He will demonstrate several examples of MATLAB applications, then conclude with a discussion of current developments, including Parallel MATLAB for multicore and multicomputer systems.
Five women in Computing Sciences contributed to the recent 2013 Grace Hopper Celebration of Women in Computing conference (GHC). Deb Agarwal of CRD worked on multiple leadership committees. NERSC’s Elizabeth Bautista gave an interactive workshop on “Building Your Professional Network.” Kirsten Fagnan of NERSC and Daniela Ushizima of CRD shared their research experiences on the “Technologies Spark Techie Data Wars” panel, which discussed medical technology and how data can be used to enlighten the science community. And Lavanya Ramakrishnan of CRD shared her career experiences on “The Quiet Success” panel that was geared towards sharing best practices for networking as an introvert. More>
