Regular PTB meeting, August 3, 2010 14:00 - 16:12 Present: Morris, Patrick, Laurence, Massimo, John, Balazs (notes) Not Present: John 1) Approval of previous meeting notes, follow up on actions Meeting notes from the following PTB meetings: *22/06/2010 (ordinary) *6/07/2010 (ordinary) *13/07/2010 (extraordinary) *15/07/2010 (extraordinary) *16/07/2010 (extraordinary) all the notes are approved. Follow up on actions: * there are no pending actions from previous meetings. 2) Discussion of infrastructure area technical objectives ("Section 5 Technical objectives" in DNA1.3.1) Decisions about objectives were directly recorded in the DNA1.3.1. The PTB run out of time, the work will be continued on the next meeting. As part of the objective discussion, the following decisions were made: Decision 1: creation of virtualization task force to address the objective "Extend job definition languages and job management services to provide access to virtualized resource managers and appliances" Morris will find a leader for the taskforce. Decision 2: creation of cloud task force to address the objective: "Integrate with off-the-shelf compute clouds systems through common interfaces" Morris will find a leader for the taskforce. 3) SAGA Service Discovery PT creation request. Balazs summarizes the request posted by Antony Wilson and Steve Fisher: A SAGA Service Discovery PT in the Infrastructure area consisting of three components: SAGA Service Discovery API, SAGA Information System Navigator API, SAGA Info Browser. These components have "ready" (not yet in production) status. Balazs also informs the PTB that there are already other EMI components dealing with service discovery (and in production). Laurence informs the PTB about the history behind the SAGA discovery libs: a work that started in EGEE-III. The libs have not yet been evaluated for glite. Morris: not sure whether the UK team's SAGA implementation work is known by the US groups working with SAGA (TeraGRId, OSG). He will follow up. Morris will investigate whether there is a potential US customer for the SAGA service discovery components. Comment was made that some convergence, harmonization of the existing production libraries and the proposed SAGA libs may be needed if SAGA service discovery is to be part of EMI stack. Morris comments that he looks at the SAGA service discovery API as an additional, different API layer. There is not necessarily a need to merge/converge SAGA and the other EMI libs. EMI may end up with several service discovery, infosys libraries. Conclusion: PTB finds the SAGA service discovery library worth to be further investigated, though it may create convergence and harmonization problems later. On the other hand the PTB has some concerns related to the SAGA WEB info browser component. No decision yet, therefore the proposed SAGA Service Discovery PT can not be listed in the DNA1.3.1 component table yet as approved PT/components. 4) AOB * Morris raises the feedback on the EGI-Inspire Roadmap draft. Balazs suggest to send the EMI workplan deliverables to EGI-Inspire as a response/feedback. * EGI Tech Forum: some idea from Patrick to organize data mini workshop. Balazs, Morris, Laurence, Patrick, John will attend the Tech Forum. * next regular PTB meeting: no regular meeting scheduled in August due to holidays. * next meeting: The PTB will continue with the infra area objectives and product team discussion Tomorrow, Wednesday 10 - 11 since Today it run out of time. ACTIONS -------- *Balazs: schedule the "EMI roadmap for the compute interface" topic for a subsequent PTB meeting. * Morris: contacts the US SAGA community. * Morris: finds infra area taskforce leaders
