Global Ring Network for Advanced Applications Development

Grid/e-Science Project

High performance computing is a technology of great importance in our modern science fields. Scientists seek new knowledge by using supercomputers. However, even though TeraFlops supercomputers exist, scientists still need faster computers. There are always more complex problems which cannot be solved by the most powerful computers in the world. The Grid technology can provide a solution to this problem. It forms a huge computing resource, data repository and a virtual experimental laboratory. Nowadays, in many developed and developing countries, the Grid enabled application, namely, e-Science is the hottest issue. Many countries are supporting their e-Science projects with large budgets. In Korea, extremely powerful research environments for Grid computing, utilizing experimental facilities and human networks are being made available with the national Grid project. On the basis of the Grid infrastructure and scientific applications’ essential software, the Korea National e-Science project will support a variety of usage models for applications. Applications can use the infrastructure to access individual resources that can be used together. For instance, astronomers can combine astrophysical data obtained by multiple telescopes or numerical simulations through the Korea National Virtual Observatory project. Data mining, filtering and analyzing the data are accomplished with high-end computers linked with the data collection. Some applications will need to execute with cutting-edge experimental facilities, high performance supercomputing resources, and data storage with a huge amount of capacity. The Korea national e-Science project will provide grid technology and high speed networks, KREONET for domestic needs and the GLORIAD for internal ones, for the next generation of science and engineering advances. The fabric of the Korea National e-Science project will encompass a wide spectrum of small to very large-scale resources integrated via a complex software system which will support remote access, resource aggregation, and provide capability beyond which is typically available to an individual scientist. The development of the complex software and hardware system will be a cutting-edge activity that will require substantive design, development, deployment and evolution.
