PPoPP'07 Conference Early Registration Deadline Is February 23

The ACM SIGPLAN 2007 Symposium on Principles and Practice of Parallel Programming (PPoPP'07) will be held in San Jose, CA, March 14-17, 2007. The deadline for discounted early registration is February 23.

The goal of the PPoPP Symposia is to provide a forum for papers and posters on the principles and foundations of parallel programming, tools and techniques for parallel programming, and experiences in using parallel programming to solve applications problems. This year’s program includes two keynote addresses, 22 presentations, 18 posters, and three tutorials. PPoPP'07 will be co-located with the 2007 International Symposium on Code Generation and Optimization (CGO'07) at Hotel Valencia in San Jose.

Kathy Yelick, head of the Future Technologies Group in CRD, is General Chair of PPoPP'07, and John Mellor-Crummey of Rice University is Program Chair. Assisting Kathy in organizing and publicizing the symposium are Costin Iancu and Parry Husbands of CRD and Yeen Mankin and John Hules of Computing Sciences.

More information on PPoPP'07 is available at http://ftg.lbl.gov/ppopp07/. To register online, go to http://ftg.lbl.gov/ppopp07/reginfo.html.

SC07 Submissions Will Open Soon

Submissions for SC07 will open on March 12, 2007. Authors of technical papers need to note several changes that have been made for 2007 to ensure a rigorous, high-quality review of all submissions.

This year a two-part submission process will be used. Authors of technical papers and Gordon Bell Prize papers need to register at the submission web site (http://sc-submissions.org) and submit an abstract no later than Friday, April 6. Then, manuscripts need to be uploaded by 11 pm EST on April 9.

A so-called “blind” submission and review process will be used at SC for the first time. Papers should be submitted without the authors’ names on the manuscript. Moreover, authors should make a reasonable effort to hide their identity. Citations to the authors’ own prior work should be included, but referred to in the third person. Acknowledgments should be omitted. Other identifying references should be removed to the extent possible.

Papers must be submitted in PDF format (readable by Adobe Acrobat Reader 4.0 and higher) and formatted for 8.5 x 11 in. paper.

Papers should be formatted in single column, 10 point font, double spaced, up to a maximum of 20 pages, including figures, tables, references, and appendices. Normal margins should be used. Papers that exceed these limits will be rejected at the discretion of the program committee.

There are no changes in submission process or format for tutorials, panel sessions, or workshops.

Zhengji Zhao Moves from Scientific Computing Group to NERSC

Zhengji Zhao, who has been a postdoc in CRD’s Scientific Computing Group (SCG) since 2004, working with Juan Meza and others on computational nanoscience, has accepted a position in the NERSC Division. She will start today as a consultant in the User Services Group. For a few months, Zhengji will be half time in CRD and half time in NERSC, becoming full time in NERSC some time around May.

In SCG Zhengji developed two new methods for computational nanoscience: the linear scaling 3D fragment (LS3DF) method for large-scale electronic structure calculations, and a new motif-based Hessian matrix method to estimate a preconditioner for nanostructures, which speeds up the convergence of atomic relaxation by at least a factor of four. Zhengji received her Ph.D. in computational physics from New York University for developing the reduced density matrix (RDM) method for electronic structure calculations, a highly accurate alternative to wavefunction-based computational chemistry methods. She received an M.S. in computer science from the Courant Institute of Mathematical Sciences, New York University; an M.S. in theoretical physics from Peking University in Beijing, China; and a B.S. in theoretical physics from Jilin University in Changchun, China.

Scientific Computing Group Welcomes Philip Sternberg

Philip Sternberg has joined CRD’s Scientific Computing Group (SCG) as a postdoctoral fellow. He will be working with Chao Yang and Esmond Ng on a single particle reconstruction project and a nuclear physics SciDAC project. Philip recently received his Ph.D. in Mathematics from UC Davis. He was a student intern in the SCG last summer.

Oklahoma Supercomputing Symposium Seeking Submissions

The University of Oklahoma Supercomputing Center for Education and Research will present the sixth annual Oklahoma Supercomputing Symposium on Wednesday, October 3, at the University of Oklahoma, Norman campus. The symposium will be free (including meals) and will run from 8:00 am to 5:30 pm, with a reception and poster session on Tuesday, October 2, from 5:30 to 7:00 pm.

The symposium organizers are looking for talks, briefs, BoFs and posters in a variety of areas of computational science and engineering, including high performance computing, high performance networking, Grid computing, data mining, scientific visualization, HPC education, and computational research in every field of engineering, physical science, biological science, mathematics, social science, business and the arts.

The keynote speaker will be Dr. Jay Boisseau, Director of the Texas Advanced Computing Center, speaking on “How to Build the Fastest Academic Supercomputer in America — Twice in One Year.” There will also be a vendor exposition.

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.
