Philosophy

• One Grid (Grid-Ireland) supporting many virtual
  organisations
• CosmoGrid is the first of these
• Start with a (hopefully!) straightforward
  computational grid.
• Use this to spawn further data-grids,
  knowledge-grids etc.

4
Objectives of CosmoGrid

• Astrophysics
• High Energy Phenomena
• Star formation
• Geophysics
• Seismic inversions
• Rheological modelling
• Digital rocks
• Atmospheric Physics
• Regional climate modelling
• Atmospheric aerosol modelling

5
Character of problems

• Causal classical systems ? well suited to simple
  Beowulf type clusters.
• Significant overlap in methods, even in
  underlying mathematical model (eg CFD).
• Computationally sophisticated user communities.

Well placed to exploit the resource sharing
fundamental to the Grid concept.
6
Proposed Implementation

• Three large Beowulf clusters interconnected over
  the Grid.
• Dedicated Grid gateway machines in each site
  centrally monitored and administered by
  Grid-Ireland.
• Extensive use of VRVS for collaboration (might
  switch to access grid)

7
Organisational Problems

• How do you foster a sense of community and of
  belonging in a virtual organisation?
• What legal structure is appropriate for a virtual
  organisation?
• How do you resolve conflicts of interest in the
  case of multiple overlapping VOs?

8
Future Directions

• Data-grid(s)
• Knowledge grid(s)
• e-Scholarship, not just e-Science
• Europeanisation and Globalisation
