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 Computing Sciences Area at Lawrence Berkeley National Laboratory provides the computing and networking resources and expertise critical to advancing Department of Energy Office of Science research missions: developing new energy sources, improving energy efficiency, developing new materials, and increasing our understanding of ourselves, our world, and our universe.

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 13 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’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 energy.gov/science.
