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
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.
