PRESENT

Christian, Elisabetta, Oliver, Paul, Zsombor

NOTES

The Compute Area has been contacted for requirements and at the moment there are none.

The Castor team has been contacted and they will follow progress but have no plans to join the group.

Zsombor asked about the 'EMI technical objectives' which stated there would be a GLUE2.0 enabled client available for EMI1.0. Is this the case, and which one? Oliver to follow up with EMI. (done... no answer yet).

After discussion on how to encapsulate our decisions, in the first instance the group will produce a FAQ style document of decisions, which can be adapted later if necessary. The spec is complete enough that it does not need to be replicated in a second annotated document.

Consequently such decisions are not recorded in the minutes, but at the following URL:

ACTIONS

Everybody to review again the attributes and indicate if there are any which the WG should declare as mandatory

Paul to write a one paragraph proposal on how to handle the UserDomain

Oliver to ask Patrick to put a general call for input on usecases into his EMI AH presentation.

QUESTIONS

How can SEs publish SE specific metadata?

Do we need to allow publishing of the entire managed capacity?

Do we need to extend the 'installed capacity' doc for GLUE2.0?

Meeting 8th October 2010, 10:00 AM CEST

Agenda:

  • Establish the services and clients concerned
  • Discuss how to achieve the objectives:
    • Understand mapping of 1.3->2.0
    • Establish if we can satisfy all obligatory 2.0 attributes
    • Identify any optional attributes we will use
    • Agree on interpretation of attributes if necessary
    • Encapsulation of above in a 'profile'
  • Validation tests
  • Configuration

Meeting minutes:

EMI JRA1 Data : Glue 2.0 8th October

Present: Elisabetta, Jean-Philippe, Jon, Oliver, Zsombor Apologies: Christian, Paul

DECISIONS:

Services concerned are : dCache, DPM, STORM gLite's FTS & LFC will have to move to GLUE 2.0, but this doesn't need explicit coordination in this forum.

ARC will maintain an interest in the group from the client side, but are not responsible for the provision of a relevant service.

We assume an ldap infrastructure, implemented with BDIIs.

According to the original GLUE 2.0 rollout plan (pre-EMI), the services should first publish correctly and then subsequently clients be adapted. The infrastructure is 'GLUE 2.0' ready, and info will be published in a parallel ldap tree.

Validation via reusable gstat 2.0 plugins was seen as a good idea (we may get further input from Paul here though).

All three services use YAIM for configuration, so a standard interface here should be maintained.

ACTIONS

dCache, DPM, STORM:

For the next meeting, supply a list of points for discussion on GLUE 2.0: problematic mandatory attributes (eg ambiguous, difficult to satisfy...) candidate optional attributes to be made mandatory candidate mappings back to existing 1.3 attributes risks, eg required attributes outside our control (eg UserDomain)

Oliver / Christian:

Clarify UNICORE involvement

Oliver:

Request input from Compute Area
