Discussion Matrix I

• Tuesday, Feb 11, 1500-1630, this room??
• Meeting all WPs
• review of integration achievements
• GridBench PPC need WP1 kernels
• who will test our tools ?
• Tuesday, Feb 11, 1700-1745, Seminario 2, 45
  mins enough?
• WP2 meets Task 3.1
• portals for GridBench, G-PM PPC
• Tuesday, Feb 11, 1745-1830, Seminario 2
• WP2 meets Task 3.3
• interfaces of GridBench G-PM to OCM-G
• use of R-GMA by GridBench

14
Discussion Matrix II

• Wednesday, Feb 12, 900-1030, Seminario 2
• WP2 internal
• plans for yearly review
• plans for next year
• how to create a real environment
• GridBench needs API from G-PM
• checking GridBench with MARMOT ?
• Wednesday, Feb 12, ??, room ??
• Task 2.4.2 already met Task 3.3.1-3.3.4
  yesterday
• Grid Monitoring Tasks will deliver input for
  PPC
• Wish to meet WP1 flooding, weather
  forecast, air polution

Issues during last weeks

• Timing
• D2.3 due on 18/01/2003 4-6 weeks ahead of
  original plan
• D2.3 delivered on 18/01/2003 not yet received
  review reports
• results of testing installation were planned
  as part of D2.3
• Tools
• vision was one environment, common look
  feel now 4 separate tools
• tools were planned to be installed on one test
  site (FZK)
• installation what does it mean ??

? Things converged during the last days
integration meetings
Thanks to WP2 members and the Integration Team.
