David Bailey’s Research Featured in Spektrum der Wissenschaft
The work of CRD Chief Technologist David H. Bailey was recently featured in Spektrum der Wissenschaft, the German equivalent of Scientific American. In the January 2009 issue, an article entitled “Der Computer als Formelentdecker” (“The Computer as Formula Discoverer”) by Spektrum editor Christoph Pöppe summarizes recent developments in experimental mathematics. The abstract of the article reads (translated):
A computer program can discover, through targeted searches, what a numerically calculated value “actually” is. But mathematicians are not unemployed; on the contrary, by using the program, numerous relationships can be found that need proving.
A translation of the paper will appear soon on the website Papers on Experimental Mathematics.
German Researchers Will Visit LBNL on Wednesday
Leading researchers from Karlsruhe Institute of Technology (KIT) in Germany will visit Berkeley Lab Computing Sciences on Wednesday, January 28, as part of a week-long visit to California to strengthen existing partnerships and establish new research collaborations.

Travel Funding Available for Tapia and Hopper Conferences
Through the generous support of Horst Simon, the Computing Sciences Diversity Working Group has travel funding available to sponsor a few employees to attend the Richard Tapia Celebration of Diversity in Computing (Portland, April 1–4, 2009) and the Grace Hopper Celebration of Women in Computing (Tucson, Sept. 30–Oct. 3, 2009). If you are interested in attending one of these conferences, please send a note to email@example.com with the following contents: Your name, your group and department, the conference name, and a paragraph describing why you would like to attend the conference. The deadline for submitting the above information is February 9, 2009.
Registration has just opened for the 2009 Richard Tapia Celebration of Diversity in Computing Conference. Early bird registration, with discounted registration fees, closes on March 1, 2009. March 1 is also the date by which hotel reservations should be confirmed.
The conference theme of “Intellect, Initiative, Insight, and Innovation” will be featured in all aspects of the event, including papers, panels, workshops, posters, Birds-of-a-Feather sessions, a Doctoral Consortium, and a Robotics Competition. While the Tapia Celebration is centered on an extensive technical program, the conference also provides a supportive networking environment for under-represented groups across the broad range of computing and information technology.
NSF and UCB Offer Research Experiences for Undergraduates
The National Science Foundation funds a large number of Research Opportunities for Undergraduate students through its REU Sites program. An REU Site consists of a group of ten or so undergraduates who work in the research programs of the host institution. Each student is associated with a specific research project, where he/she works closely with the faculty and other researchers. Students are granted stipends and, in many cases, assistance with housing and travel. Students must contact the individual sites for information and application materials.
The UC Berkeley Department of Electrical Engineering and Computer Sciences is an REU Site with its SUPERB-CSIS program (Summer Undergraduate Program in Engineering Research at Berkeley—Computer Science in the Interest of Society). The research focus of SUPERB-CSIS is computer science in the context of solving societal problems, including health, national security, and technology for underdeveloped countries.
Feb. 15 Application Deadline for CRA-W Grad Cohort for Women
CRA-W is announcing the formation of the Sixth Grad Cohort for Women. Cohort activities will kick off with a workshop March 27-28, 2009 in San Mateo, CA. This workshop is the cornerstone of CRA-W's Grad Cohort Program to increase the ranks of senior women in computing by building and mentoring nationwide communities of women through their graduate studies. Through this workshop, students will be able to build mentoring relationships and develop peer networks that will form the basis for ongoing activities during their graduate careers. Travel expenses, meals and lodging will be provided for students chosen to participate in this program. The application deadline is February 15, 2009.
International Data Challenge Competition Announced
On January 16, a new, international competition called the Digging into Data Challenge was announced by four leading research agencies: the Joint Information Systems Committee (JISC) from the United Kingdom, the National Endowment for the Humanities (NEH) and the National Science Foundation (NSF) from the United States, and the Social Sciences and Humanities Research Council (SSHRC) from Canada.
The idea behind the Digging into Data Challenge is to answer the question “What do you do with a million books?” Or a million pages of newspaper? Or a million photographs of artwork? That is, how does the notion of scale affect humanities and social science research? Now that scholars have access to huge repositories of digitized data — far more than they could read in a lifetime — what does that mean for research?
Applicants will form international teams from at least two of the participating countries. Winning teams will receive grants from two or more of the funding agencies and, one year later, will be invited to present their work at a special conference. These teams, which may be composed of scholars and scientists, will be asked to demonstrate how data mining and data analysis tools currently used in the sciences can improve humanities and social science scholarship. The hope of this competition is that these projects will serve as exemplars to the field and encourage new, international partnerships among scholars, computer scientists, information scientists, librarians and others.
This Week’s Computing Sciences Seminars
Challenges of High Performance Computing in Structural Industrial Finite Element Analysis
Wednesday, Jan. 28, 11:00 am–noon, 380 Soda Hall, UC Berkeley
Louis Komzsik, Chief Numerical Analyst, Office of Architecture and Technology, Siemens PLM Software
The new millennium brought significant new challenges to high performance computing in industrial finite element analysis. Millions of node points and tens of millions of degrees of freedom are now commonplace. These are mainly results of the recent significant advancements in computer aided design tools and the increased use of analysis early in the design phase. The industry application focus has been extended from simply verifying structural integrity to product life-cycle simulation. The outcome of this is an increased use of coupled analyses yielding more difficult computational problems.
A third challenge is presented by the radical paradigm shift in the computational environment. Most of the modeling activities in the industry are now executed on personal computers, and there is a desire to do the analysis on clusters of such platforms as well.
The computational solutions to these challenges are also rather complex. The first challenge is addressed by partitioned solution of linear systems and eigenvalue problems. The second challenge gave a boost to symmetric reformulation and reduced order techniques. The third challenge resulted in the emergence of distributed memory parallel computational strategies for clusters of processors.
The presentation will review the computational challenges and present commercially useful high performance computing solutions.
Beyond Transistor Scaling: New Devices for Ultra-Low-Energy Information Processing
Wednesday, Jan. 28, noon–1:00 pm, 290 Hearst Memorial Mining Bldg., UC Berkeley
Tsu-Jae King Liu, Professor of Electrical Engineering and Computer Sciences, UC Berkeley
Online live broadcast: mms://media.citris.berkeley.edu/webcast
The rapid growth of the semiconductor industry over the past four decades was enabled by the steady miniaturization of the transistor with each new generation of CMOS technology, which provided for continual improvements in integrated-circuit performance and cost per function. Transistor scaling has slowed recently, however, due to fundamental limits leading to increases in power density. In this seminar, I will discuss alternative switching device designs that can potentially overcome the energy-efficiency limitations of CMOS technology to help usher in the Age of Ubiquitous Computing.
