1. Thousand years ago : Experimental Science
Description of natural phenomena
2. Last few hundred years : Theoretical Science
Newton’s Laws, Maxwell’s Equations…
3. Last few decades : Computational Science Simulation of complex phenomena
4. Last few years : e-Science or Data-Intensive Science
Scientists overwhelmed with data sets from many different
sources
Data captured by instruments
Data generated by simulations & sensor networks
e-Science is the set of tools and technologies to
support data federation and collaboration
For analysis and data mining
For data visualization and exploration
For scholarly communication and dissemination

2.9 IDC Innovation Excellence Award
EDISON (EDucation-research Integration through Simulation On the Net)
“HPC Innovation Excellence Award” from IDC, the first time in Korea
Grounds for the Award
- By decreasing dependence on expensive commercial simulation software and
providing the free locally developed domain specific simulation software
through the development/establishment of EDISON platform & core technologies based on
HPC(High Performance Computing), our innovative competence has been recognized.
- Our contribution to the spread of HPC community in the area of computational science engineering
through the establishment of close partnership between the central center and application center
has been recognized. * Central Center: Developing EDISON core technologies and establishing platform for running simulations based on the HPC
** Special Center: Developing simulation SW in the areas of computational science engineering and applying it to education

Initiating collaboration between KISTI, Korea & ICST, Vietnam
Background Peter and Ruth was invited to ICCSE2014@Ho Chi Minh City (Aug. 21-23, 2014)
Consulted with Dr. Thanh N. Truong, head of ICST(Institute of Computational Science and Technology), Vietnam, to pursue business cooperation between the two organizations to establish a cyber education and research environment in Vietnam just as the EDISON and perform talent cultivation ODA(Official Development Assistance) programs based on computational science-related business cooperation and UST(University of Science & Technology, Korea) program.
Goal To build a starting point to expand the EDISON project in ODA recipient states in South East Asia and beyond
Cooperation Outline Build a cyber research and educational environment via ODA projects (EDISON@Vietnam) and Vietnamese
EDISON communities
Share simulation programs and contents developed by the EDISON project to attract Vietnamese users
Provide training programs to Vietnamese researchers (UST masters/doctoral courses) through the UST program and support mutual visiting research and exchanges.
Pursue joint studies in computational science based on supercomputing and network to come up with quality performance.
Arrange workshops and fulfil as a center of super computing technology development and computation science research and cooperation between the two states.
Expected benefits Facilitate the ODA project based on EDISON findings and the strategic point of Viet Nam and expand EDISON
users further into South East Asia and other ODA recipient states
