everybody has noticed and would agree You have
to Grid People before you can Grid machines 

• Rajesh Chhabra

Lessons Learned From Grid Interoperation
http//forge.gridforum.org/sf/wiki/do/viewPage/pro
jects.gin/wiki/GinOps

• Grid interoperation make large scale calculations
  possible
• Differences among grids provide learning,
  collaboration and integration opportunities
• IGTF, VOMS (GIN)
• Common Software Area (TeraGrid)
• Ninf-G NorduGrid
• Nimrod/G Unicore
• SCMSWeb Condor
• SCMSWeb BDII
• SCMSWeb probe matrix for GIN testbed monitoring
• Common schema among many grid monitoring software
• VDT (OSG) and Rocks (SDSC/PRAGMA) integration
• Differences in grid environment are source of
  difficulties for users and applications
• Different user access setup procedure - take
  extra effort
• Different job submission protocols
• GRAM, Sandbox, gridftp, modified GRAM,
• One-to-one interface - is it scalable? Possible
  standards?
• Middleware fault tolerance and flexible resource
  management is important
• Cope with unfamiliar fault conditions, lack of
  parallel computation support,

Summary

• PRAGMA grid
• Shared vision lower resistance to use others
  software, test on others resources
• Formed new development collaborations
• Size and heterogeneity, explore issues which
  functional grid must resolve
• Management, resources and software coordination
• Identity and fault management
• Scalability and performance
• Feedback between application and middleware help
  improve software and promote software integration
• Heterogeneous global grid
• Is realistic and challenging
• Can be good for middleware development and
  testing
• Can be useful for real science
• Impact
• Software dissemination (Rocks, Ninf-G, Nimrod,
  SCMSWeb, Naregi-CA, )
• Help new national/regional grids (Chile, Vietnam,
  Hong kong, )
• Key is people, is collaboration

44
How Can I Participate?

• Get involved now
• PRAGMA or similar collaborative communities
• Cost a little
• Benefit a lot
• Being a part of larger grid effort
• Learn from doing
• Build collaborations
• Develop bigger/better ideas/projects
• Push the use of network and other infrastructure

45
A Grass Roots Effort

• One of the most important lessons of the
  Internet is that it grows most successfully where
  grass roots initiatives are encouraged and
  enabled. The Internet has historically grown from
  the bottom up, and this aspect continues to fuel
  its continued growth in the academic and
  commercial sectors.
• Vint Cert, UN Economic and Social Council in 2000

• PRAGMA is supported by the National Science
  Foundation (Grant No. INT-0216895, INT-0314015,
  OCI -0627026) and by member institutions
• PRIME is supported by the National Science
  Foundation under NSF INT 04007508
• PRAGMA grid is the result of contributions and
  support from all PRAGMA grid team members
