This year’s list of the world’s 500 most powerful computers is now out. Produced annually by the Lab’s Horst Simon, Erich Strohmaier and colleagues, they were interviewed this week by HPC Wire. To listen, go here.

While serving as the Lab’s deputy director, Horst Simon still maintains his strong ties to the scientific computing community as an editor of the TOP500 list and invited speaker at conferences. Earlier this month, Simon gave back-to-back presentations of a new talk on “Why We Need Exascale and Why We Won’t Get There by 2020.” Not only was the talk a hit with conference attendees, but it also made its way onto Slashdot. In this HPCwire exclusive, Simon talks about his presentation with Jon Bashor of Berkeley Lab. More>
As the 2013 Luis Alvarez Fellow in Computing Sciences, Robert Saye will be developing numerical methods and computational tools for studying a wide range of problems involving multiple evolving interfaces. His methods will also have applications in multi-region shape optimization and image segmentation. More>
Satellite observations suggest that the shrinking West Antarctic ice sheet is contributing to global sea level rise. But until recently, scientists could not accurately model the physical processes driving retreat of the ice sheet. Now, a new ice sheet model — called Berkeley-ISICLES (BISICLES) — is shedding light on these details, with the help of Lab computing scientists. This video shows one possible scenario for Antarctica’s rapidly changing Amundsen Sea Embayment at two different model resolutions over a period of 218 years (from 1982 to 2200). More>
As part of Berkeley Lab Computing Sciences’ ongoing outreach efforts with the Kennedy High School IT Academy in Richmond, 11 students and two teachers visited the Lab last Wednesday and spent a half day learning about different career opportunities in computing and networking. The event was organized to give the students ideas about career paths beyond the basics of computer science and web design taught in the classroom. More>
Associate Laboratory Director for Computing Sciences Kathy Yelick was named the 2013-2014 Athena Lecturer by the Association for Computing Machinery’s Council on Women in Computing. Yelick, also a professor at UC Berkeley, has improved the fundamental understanding and practice of parallel programming. In addition to programming language extensions for parallel machines, she developed novel performance tuning, compilation and runtime systems. The Athena Lecturer award celebrates women researchers who have made fundamental contributions to computer science. The Athena Lecturer presents an invited lecture at an ACM event and Yelick’s presentation will be delivered at SC13 in Denver, Colo. More>
In celebration of Women’s History Month, the Department of Energy is featuring “Women @ Energy,” which showcases talented and dedicated employees at the Energy Department. Women @ Energy profiles women across the country who share insights on what inspired them to work in STEM fields (Science, Technology, Engineering and Mathematics). Several Berkeley Lab researchers are included in the feature, including Susannah Green Tringe (JGI), Rachel Segalman (Materials Sciences), Natalie Roe (Physics), Mina Bissell and Jill Fuss (Life Sciences), Kathy Yelick (Computing Sciences), Dawn Munson (Engineering), Gabriel Orebi Gann (NSD), and (pictured) Aindrila Mukhopadhyay (JBEI).

“Twenty-four hours a day, seven days a week, servers are ready to respond to the explosion of digital information that we generate every time we use the internet. These data centres can use more electricity than a small town, and up to a whopping 90% of it is wasted. High-tech giants are now looking to put their machines on a miracle energy diet. France 24 went to California to find out more. ” So begins a news video from France 24 that includes excerpts of interviews with Brent Draney and John Shalf of NERSC — Draney discussing running an energy-efficient data center, and Shalf discussing his research into energy-efficient computer chips.
In honor of Women’s History Month, CNN selected 10 contemporary women researchers in fields known as STEM (Science, Technology, Engineering and Mathematics) and paired them with historical counterparts. Included in the list were Associate Lab Director Kathy Yelick, paired with pioneering computer scientist Grace Hopper, and Lab nuclear chemist Darleane Hoffman, paired with Marie Curie. Both Yelick and Hoffman also hold joint appointments as professors at UC Berkeley. Yelick’s pairing is fitting in that as director of the NERSC Center, she oversaw the installation of a Cray supercomputer named for Grace Hopper. More >
Every year, Science magazine editors and staff sift through numerous scientific accomplishments and ultimately crown one “Breakthrough of the Year.” Of the top 10 finalists for 2012, Berkeley Lab computational researchers were major contributors to two accomplishments, including the winner: Discovery of the Higgs Boson. Two Department of Energy facilities managed by Berkeley Lab — NERSC and ESnet — also provided critical support that made these breakthroughs possible. More>
