  1. WLCG Technical Forum MB 12th May 2009

  2. Need • As discussed and agreed in previous weeks: • Need for a technical forum to discuss issues for evolution, improvement, etc between WLCG stakeholders • Able to provide input on a common WLCG position to e.g. EGEE, EGI, OSG, etc. • Forum in which to discuss longer term needs and developments of middleware and other services • Must prepare for the sustainability and evolution of the existing middleware in the light of changing technology and experience – • Can we think again of common solutions in some areas where it is clear that existing solutions are weak? • It needs to represent all the stakeholders – experiments, sites, grid projects, etc.; but should not be too large • Depending on the topic – bring in the appropriate experts • It does not take decisions – should produce clear documents for discussion in the GDB, and potential agreement in the MB

  3. Mandate • Provide detailed technical feedback and requirements on grid middleware and services, providing the WLCG position on technical issues: • Functionality, stability, interfaces, architecture, suitability • Advise the MB on grid middleware and service needs and problems. • Discuss the evolution and development of middleware and services, in particular driving common solutions where possible. • Prioritise needs and requirements. • This group reports to the MB

  4. Membership • Chair: Maarten Litmaath • Members: • Experiments: 1+1 per experiment • Sites: 1+1 for Tier 1s; 1+1 for Tier 2s; 1+1 for Tier 0 • Infrastructures: 1+1 from each EGEE, OSG, ARC • Bring in experts as needed • Members must have the mandate to speak for their community (of course also talking to them about the issues) • Meetings: • Suggest setting up a strong non-face-to-face channel • Monthly face to face/video meeting

  5. Initial topics • Data management – review where we are with SRM vs actual needs • Analysis model topics • Support for virtualisation (many sub topics) • Pilot jobs support • Technical input to EGI discussions • Needs from the NGIs • Input to proposal for the SSC for HEP • Input to the middleware discussion – we need to be explicit and clear about the WLCG needs in the near future
