Some Illustrative Aspects of these Projects
5

• Runjob
• Stakeholders use the Services in different ways
• CMS - Job Configuration Service
• D0 - Job Configuration and Execution Service
• CDF - do not use Runjob yet.
• Must support and evolve existing implementations
  at same time move to common core
  infrastructure.
• Schedule and priorities of participants vary.

• VO Services
• Run II legacy systems make use of Fermilab
  infrastructure (e.g. kerberos). Interface site
  infrastructure (FNAL Kerberos) with new Grid
  infrastructure during production operations.

• Delivery to main sponsor and distributed
  contributors (BNL, LCG) requires effort and
  compromise.
• Support model for external user communities.
  (e.g. Biology at ANL)?
• Long term commitment needed for collaborations.

8

• VO Privilege
• support standard callouts from Globus Gatekeeper
  apply Site Identify/Authorization Mapping and
  User Authorization policies.
• Globus Dynamic Account developer (working also
  with EGEE) wants to collaborate
• Balance need for practical concrete deliverables
  for Fermilab VOs and commitment to participate in
  common and general services.

Joint Projects provide opportunity for Run 2 to
be involved in and influence new developments
while maintaining appropriate level of
contributions and pragmatic approach to
commitments
