NERSC's Lenny Oliker Co-Recipient of SC99 Best Paper Award

November 30, 1999

Leonid “Lenny” Oliker, a post-doctoral fellow in NERSC’s Scientific Computing Group, was co-recipient of the “Best Paper of SC99” award at SC99, the annual conference on high-performance computing and networking.

Oliker and Rupak Biswas co-authored "Parallelization of a Dynamic Unstructured Application Using Three Leading Paradigms." They implemented a mesh adaptation code on the Cray T3E, SGI Origin2000 and the Tera MTA supercomputers comparing programmability and performance. They compared several critical factors of parallel code development, including runtime, scalability, programmability, and memory overhead.  Their overall results demonstrate that multithreaded systems offer tremendous potential for quickly and efficiently solving some of the most challenging real-life problems on parallel computers.

“I’m very excited to receive this award and grateful for the opportunities I’ve had at NERSC,” Oliker said after the award was announced on Thursday, Nov. 18. SC99 was held from Nov. 13-19 in Portland, Ore.

Co-author Rupak Biswas is an employee of MRJ Technology Solutions and works in the Numerical Aerospace Simulation Division at NASA's Ames Research Center in Redwood City.

NERSC is in the second year of helping assess the performance of the only multithreaded architecture computer built by Tera Computer. The machine is installed at the San Diego Supercomputer Center.

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.
