Importance of Grid application research
• Grid applications are very important to show the feasibility of Grid technology.
• The final goal of middleware research is to use Grid for real world application.
• Therefore, the primary concern is to develop an innovative engineering
methodology using Grid technology.
Where is middleware?
• There are many available software for Grid infrastructure.
• We can continue application research by using those software.
• We can contribute to their research since they also want applications for their
software.

CFD application on Grid
• CFD is very good application for Grid since it requires huge amount of
computing resource and relatively easy to exploit Grid infrastructure.
• Many Grid research includes CFD Grid in their project.
Where is the starting point of CFD application in N*Grid?
• We start from the high throughput CFD Grid.
• It is very powerful for design optimization and parametric study.
• We need to develop necessary algorithms as well as implementations.
• The final goal is to provide Grid Service to engineers and scientists

Construction of worldwide Grid test bed
• Connection of test bed with foreign institutes
Software for Grid infrastructure
• We are willing to be beta user of middleware, problem solving environment
and job scheduler.
• Preliminary Grid service will adopt those software
Application research
• Cooperation in application research
International Collaborations

Porting CFD code to Cactus
• KISTI wants to develop truly Grid application.
• Cactus already has versatile core.
• Porting requires strong collaboration of staffs in KISTI and AEI.
• Proposed timetable
• Phase 1 : Port simple CFD code to Cactus framework(2-3 monthes)
• AEI will help porting procedure. KISTI will port CFD code.
• Phase 2 : Extend CFD code for realistic problem(TBD)
• AEI will add required core module. KISTI will implement CFD code.
• Phase 3 : Extend to integrated CAE environment.
• If both parties have interest in further development, it will be very good
change to deliver Grid technology to industry.

• KISTI wants to develop truly Grid application.
• GAT can be an ideal tool for this.
• Possible action item
• KISTI staffs can use GAT for their Grid application development
• N*Grid participants can use GAT.
• Feedback will be provided to GAT developer.
• Can KISTI contribute to GAT development (as a developer)?
• Does Gridlab have a particular application field in mind?
• What is scope of GAT?
• How application can exploit full benefits of GAT?

• Grid portal is very important topic in N*Grid project.
• KISTI is required to develop Grid portal itself for Grid infrastructure, as well as
API or other form of library for easy portal building.
• Possible action item
• KISTI can use Grid Sphere for their portal development.
• Feedback will be provided to Grid Sphere developer.
• KISTI contribute to Grid Sphere development as a developer.
• KISTI develop a customized module of Grid Sphere for a particular use.
