| | Andrew A. Chien - Professor
High performance computing and networking architecture, including grid, parallel and distributed
computing, as well as operating systems, compilers and runtimes, object-oriented languages, and scalable clusters.
Professor Chien's research focuses on "grid" computing and cuts across a broad range of
system layers. It includes both hardware and software architecture issues in large-scale parallel and distributed
computer systems such as scalable servers, and clusters and workgroups of workstations. Chien's current projects
include building optimizing compilers, fast object runtimes, high-speed communication software and hardware, and
hardware architectures for high-performance computing. Chien is on the cutting-edge of technology to harness the
"rich [low-cost] environment for desktop, distributed and wide-area computing" for high-performance parallel
computing. He is working on exploiting all-optical (DWDM) networks to couple scalable clusters at terabit speeds.
He is also working on scalable clusters--so-called "high-performance virtual machines" (HPVM)--that can reduce the
effort required to build efficient parallel applications on distributed resources, increase the performance
delivered to those applications, and leverage parallel software tools from existing parallel systems to distributed
environments. Chien is also an expert in quality-of-service (QoS) and resource management in distributed
systems.
Capsule Bio:
Andrew A. Chien joined the UCSD faculty in 1998, where he is the Science Applications
International Corporation (SAIC) Chair Professor in computer science and engineering. He received his Ph.D. in
computer science in 1990 from MIT, where he also earned his M.S. and B.S. degrees. From 1990-98, Chien held joint
appointments at the University of Illinois at Urbana-Champaign (UIUC) in the computer science as well as electrical
and computer engineering departments. Simultaneously, he was a research scientist in the UIUC-based National Center
for Supercomputing Applications. At UCSD, Chien leads the Concurrent Systems Architecture Group, and is involved
with joint projects with both NCSA and NPACI. In 1999 he co-founded Entropia, Inc., an enterprise desktop Grid
company, where he now serves as Chief Technology Officer.
