JPL TEAM WINS AWARD FOR PAPER ON EFFICIENT PARALLEL COMPUTING
A team of three computational and research scientists at
NASA's Jet Propulsion Laboratory in Pasadena, CA, are the
recipients of a prestigious award for a key paper detailing their
new code enabling faster, more efficient parallel computing. Ping
Wang, Daniel Katz and Yi Chao were awarded the $1,000 Best Paper
prize from a field of 384 entries at SC '97: High Performance
Networking and Computing, a supercomputing conference held
November 17-21. The event was co-sponsored by the Institute of
Electrical and Electronics Engineers and the Association for
Computing Machinery.
The trio's paper, Optimization of a Parallel Ocean General
Circulation Model, discusses their successful efforts to design
and implement a well-optimized code to significantly improve
computational performance and reduce the total research time to
complete complex studies.
The team applied this code to a three-dimensional
simulation, known as an ocean general circulation model (OGCM),
of the entire Atlantic Ocean, a task requiring a large amount of
memory and processing time. The general strategies employed to
optimize the OGCM included memory optimization, effective uses of
arithmetic pipelines and use of optimized libraries.
The paper is available in its entirety at the Web site for
JPL's High Performance Computing Group:
