- 1
  
  Architecture of the Tier-2s within NDGF
  
  (how do they appear to the rest of the world? as single sites with a CE and SE?)
- 2
  Storage element
  - a) Status of the virtual Storage Element that presents NDGF as a single site for storage management and data access
  - b) Analysis of the internal data rates within the NDGF Tier-1
    
    (some concern that these may be higher than currently assumed)
  - c) Operation of the File Transfer Service for communication with other Tier-1s (ATLAS) and other Tier-2s (potentially for ATLAS, definitely for CMS if NDGF is a CMS Tier-1)
  - d) Implementation of the ATLAS data placement model
    
    (RAW data and all its derivatives at the same site)
  - e) Implementation of the base SRM functionality (SRM v 2.2) and storage classes
  - f) Provision of a catalog equivalent to LFC for ATLAS
- 3
  
  Progress and plans for the distributed database service for ATLAS in NDGF
  
  (3D project)
- 4
  
  Provision of site availability metrics
- 5
  
  Model for NDGF daily operation and integration with the LCG/EGEE grid operations services
- 6
  Accounting plans
  
  see accounting presentations at the GDB (06dec06, 09jan07) and the discussions and decisions at the MB (19dec06, 08jan07)
  - a) Integration of cpu accounting with the APEL repository at the GOC
  - b) User-level accounting
  - c) Storage accounting
- 7
  
  Implementation of scheduling priorities based on VOMS groups and roles
- 8
  
  Installation schedule for 2007
- 9
  
  Status and plans for testing the distributed Tier-1 functionality and integrating into the ATLAS and ALICE services
- 10
  Organisational and management issues
  - a) Is it clear now how CMS fits in to NDGF, organisationally and technically?
  - b) Formal resource commitments for the Nordic countries and signing the MoU
  - c) NDGF representation in the WLCG Overview Board, and Computing Resource Review Board
  - d) Does NDGF feel adequately represented in the various WLCG boards, committees and meetings, and does it feel that it is well enough informed about the activity of the project?
