2. Construction of the K*Grid infrastructure

The construction of the K*Grid infrastructure is divided into two phases: the first phase (2002-2004) was for constructing Grid testbeds and providing basic Grid services with 15 small-scale cluster systems from computing centers and university laboratories. As the interests in Grid have increased, the demand for a sustainable, production level Grid infrastructure has been rapidly growing not only from users from the K*Grid project, but also from related projects such as, e-Science project of Korea and KoCED (KOrea Construction Engineering Development) project.

The second phase (2005-2006) of the K*Grid infrastructure is the result of such requirements. Its objective is to construct a reliable Grid service infrastructure for TFLOPS level. At present, three organizations, SNU (Seoul National University), PNU (Pusan National University) and KISTI, are involved. They are making invaluable contributions for sharing high-performance computing resources using the scientific research network of KREONET (Korea Research Environment Open NETwork).

The K*Grid portal, a web-based Grid service platform for providing an easy-to-use environment to the user, has been developed based on Java and web service technology. It provides a job management and execution environment, and various application modules will be integrated later based on requirements from application researchers. The K*Grid infrastructure is expected to be used in diverse fields, far beyond traditional applications of supercomputing. It is expected to play a pivotal role in R&D in Korea as the research and development cyberinfrastructure of Korea.

AG activity in Korea started in 2002 as a part of the K*Grid project. The AG infrastructure of Korea started as a one room type node at KISTI and developed into a six room type with over fifty PIG (Personal Interface to the Access Grid) nodes that are actively used in such areas as e-Science, bioinformatics, medicine, meteorology. The long term goal of AG activities in Korea is to provide enhanced AG systems as the next generation high-end collaborative infrastructure for researchers in Korea.

In order to facilitate a domestic AG community, KISTI develops various additional AG servers, provides enhanced services and technical support, and holds annual workshop and tutorials. KISTI also has been conducting research to enhance the performance of the AG infrastructure, such as a high quality media stream transmission and a high adaptive network compatibility tool for AG connector, which provides easy access from several types of networks such as NAT, VPN, and through firewalls. MEET (Multicast Debugging Toolkit with End-to-End Packet Trace), a near real-time multicast accessibility and quality monitoring framework with a web-based graphical user interface, is also being developed. MEET is able to (1) carry out proactive multicast diagnosis, and (2) provide easy accessibility for multicast users via the toolkit. In addition, an HDTV media steam transmission over AG technique has been developed and deployed, and international joint research with ANL toward building the next AGTk (Access Grid Toolkit) with an AGPM (Access Grid Package Manager) technique is in progress.

AG is being used in increasingly diverse situations, such as remote medical examination and treatment, bioinformatics, and education. In particular, usage in the medical area is very significant –– it is currently used in remote lecture, remote presentation, remote workshop, and it is expected that usage in remote surgery as well as remote collaborative medical examination and treatment will be popular in the near future. KISTI’s AG has also been used to help international collaboration in such areas as Grid, supercomputing application research, medicine and bioinformatics.
