3. Many Faced Cyberinfrastructure Panel Topics
We have two faces and one can define two expressions for each face to get 4 expressions of Cyberinfrastructure
Petascale machines
Grids of "modest" Clusters of Multicores
Web 2.0 style sites and technologies
Web Service/OGSA/Globus style Grid Infrastructure
Some Questions for these expressions
a) Contrast the probably discipline specific benefits to and requirements from escience of each Cyberinfrastructure expression
b) Comment on maturity, Academic interest, Industry interest and Government investments in the different expressions of Cyberinfrastructure
c) How will these expressions of Cyberinfrastructure look 5 years from now (i.e. extend Moore's law to Atkins' law!)
d) How does all this impact your favorite organizations: Grid2007, Microsoft, NSF, OGF,  TACC, TeraGrid, UK eScience
e) How do different faces and different expressions compete and complement each other
