7-9 March 2001       DATAgrid Conference - Amsterdam   2
                  Goals of Testbed 0 release
• Grid basic services deployment at european level, based on
  Globus toolkit; main coordination issues are:
     – Information services
     – Resource access:Certification, Security and policies management
     – Installation kit and documentation

• Network layout monitoring tools
• First Grid Middleware tests
• First Grid Applications tests

                     Working model
• Goal: Testbed has to provide the grid-layout for test
  activity of each WP and organize the software release
  validation process.
• Working model defines the validation process of each
  software package released by the DATAGRID Work
  Packages.




7-9 March 2001     DATAgrid Conference - Amsterdam        4
                    Working Model
1. WP test activity: Testbed WP will provide the basic layout
   for test activity of each DATAGRID WPs.
2. WP Release: a team of people from WPs, applications,
   testbed and network will organize the test environment for
   this release, do the tests, provide feedback to the WP and
   validate the release for the next test phase.
3. Testbed Release : the previous software release will be
   integrated to the last official testbed release. This new
   release will be tested in a larger environment in order to
   be validated for the next final testing phase.
4. Official Testbed Release:a new team including also
   users will organize a quasi-production environment in
   order to certificate this release as new official testbed
   release.

• Temporary groups set up for each specific WP release to
  certificate the different release validation phases. For each
  release the membership has to be set up.

   – the software code is owned by the WPs.
   – Testbed WP organizes the „release certification‟ and
      distribute the installation kit of the integrated WP
      releases also called “Testbed official release”.
