Motivation for a Seismology Virtual Org.
• Attract knowledge workers / researchers to use e-infrastructures • According to Roberto Barbera, University of Catania and INFN
– EC funding for EGEE-III : 1.4 k€ per user per year (11.7 k users)– EC funding GEANT3 : 0.8 € per user per year (30 M users ) – Reference (EGEE 09 Conference, Barcelona):

Research Approach and Methodology
• Use distributed storage and serving of data• Index and organize data logically
– Aim data location independence
• Build Programming tools for accessing data – called Virtual Organization Specific Iterators
• Gridify six seismology applications

Conclusion and outlook
• Engineering/scientific curriculums include programming classes (C/Fortran/C++)
• Address engineers’/scientists’ needs by providing data iterators• Iterators relieve the user from the need to learn XML, web services,
parsing, etc...• Iterators
– Take couple of hours to learn
– Targets power users (scientists/researcher)
– Provides flexibility, performance
– Requires minor coding changes in legacy codes
• XML, web services, parsers– Take days, months to learn
