The goal of research at the Universal Grid Computing Laboratory (UGC Lab) is to develop a universal grid computing system and architecture which can adapt to large-scale dynamic computing environments, facilitate application development, and improve runtime performance as well. The members of the UGC Lab are also interested in recent technology advances in computer science related fields, such as e-science and e-social-science. The current research direction in the UGC Lab focuses on three topics:
Large-scale distributed programming technology to facilitate worldwide-scale application development
Generic distributed scientific computing framework
Peer-to-Peer systems
Large-Scale Scientific Computing Application, System, and
Architecture in Astronomy:
PANoramic Survey Telescope And Rapid
Response System (Pan-STARRS) is a planned astronomical survey that will
conduct astrometry and photometry of 3/4 of the entire sky every night. The
major goal of Pan-STARRS is to detect potentially hazardous objects, in
particular the near-earth objects in the Solar System. PS1, essentially one
quarter of Pan-STARRS, is the prototype of the Pan-STARRS, and is also expected
to have significant contribution in many areas of astronomy research. Pan-STARRS
is currently operated by the
University of Hawaii, which has set up an international consortium comprised
of research groups in Germany, the USA, the United Kingdom, and Taiwan. The
observed data from PS1 will be about 2-3 Terabytes per night which takes a long
time to finish data analysis. Therefore advanced computing technology,
especially grid/p2p computing technology, is required to improve
performance. Furthermore, many astronomy applications may also utilize the data
from PS1 to do their own analysis, which means there exist many research
potentials for universal grid computing in this area. The UGC Lab is collaborating with the
Graduate Institute of Astronomy at National Central University, Taiwan, on
PS1 related research.
Worldwide Computing Environment (sponsored by NSC, Taiwan,
NSC97-2221-E-008-046-):
The purpose of this research is to turn the Internet into a unified, worldwide
computing environment, which harnesses under-loaded computing resources by the
technique of dynamic system reconfiguration in a peer-to-peer manner. The
major testbed and toolkit used in our worldwide computing environment research
is Simple Actor Language, System, and
Architecture (SALSA), a distributed actor-based programming language
which supports actor migration, coordinated asynchronous message execution,
automatic actor garbage collection, and universal actor naming. Investigating
distributed programming framework on dynamic grids and efficient distributed
actor garbage collection are the current concerns of the UGC Lab in this
project. The
Worldwide Computing Laboratory
at Rensselaer Polytechnic Institute in the US is our major collaboration
partner in this project.
