  8. Security Certificates • The project software supports 12 Certification Authorities from the various partners involved in the project • http://marianne.in2p3.fr/datagrid/ca/ca-table-ca.html • For a machine to participate as a Testbed 1 resource allthe CAs must be enabled. • all CA certificates can be installed without compromising local site security • Each host running a Grid service needs to be able to authenticate users and other hosts • site manager has full control over security for local nodes • Virtual Organisation represents a community of users • 6 VOs: 4 HEP (ALICE, ATLAS, CMS, LHCb), 1 EO, 1 Biology Account Registration Usage guidelines EU DataGrid

  9. rdxprof ldxprof LCFG configuration files HTTP Generic Component mkxprof Web Server DBM File LCFG Components XML Profile (one per client node) Server node Client nodes Node configuration tools Node configuration and installation tools For reference platform (Linux RedHat 6.2) Initial installation tool using system image cloning LCFG(Edinburgh University) for software updates and maintenance Total of ~750 RPMs With a 10Mbit/sec link need just 10 mins to install anode EU DataGrid

  10. Lessons learnt from testbed 1 • The raw ingredients exist – we just need to be sure of the recipe • Sufficient expertise exists in the different institutes to cover all aspects of the project • Expertise and enthusiasm needs to be channeled using agreed framework • CERN central role underestimated and under resourced • Integration and deployment is a labour intensive task • More planning & WP6 (sw integration) needs reinforcement (especially at CERN) • Better done in small steps using iterative releases • Support by and relationship with Globus developers is very important • International Aspects • Already an international testbed, need to agree plans with US similar activities • Underestimated the administrative effort involved in running an international testbed • Need more emphasis on testing • More unit & integration testing • Middleware WPs need to develop a test-plan (also WP6 for external packages & integration tests) and involved applications from early stage EU DataGrid

  11. Iterative Releases • Planned intermediate release schedule • TestBed 1: October 2001 • Release 1.1: January 2002 • Release 1.2: March 2002 • Release 1.3: May 2002 • Release 1.4: July 2002 • TestBed 2: September 2002 • Each release includes • feedback from use of previous release by application groups • agreed high-priority improvements/extensions • use of software infrastructure • feeds into architecture group • Similar schedule will be organised for 2003 EU DataGrid

  12. Release Plan . . . . . . . . . Release feedback Release Plan++ WP meetings Software Release Procedure • Coordination meeting • Gather feedback on previous release • Review plan for next release • WP meeting • Take basic plan and clarify effort/people/dependencies • Sw development • Performed by WPs in dispersed institutes and run unit tests • Software integration • Performed by WP6 on frozen sw • Integration tests run • Acceptance tests • Performed by Loose Cannons et al. • Roll-out • Present sw to application groups • Deploy on testbed Coord. meeting themed tech. meets Component 1 Component n WP1 WP7 WP3 Globus EDG release Distributed EDG release testbed 1: Dec 11 2001 ~100 participants Roll-out. meeting EU DataGrid

  13. Development & Production testbeds • Development • Initial set of 5 sites will keep small cluster of PCs for development purposes to test new versions of the software, configurations etc. • Production • More stable environment for use by application groups • more sites • more nodes per site (grow to meaningful size at major centres) • more users per VO • Usage already foreseen in Data Challenge schedules for LHC experiments • harmonize release schedules Participating in InterGrid discussions on testbed organisation Antonia Ghiselli, Bob Jones, Francesco Prelz Analysis of interface with US testbeds to be performed by end of April (GriPhyN/PPDG meeting) EU DataGrid

  15. Future Plans • Prepare for first project EU review 1st March 2002 (“managed panic”) • Expand testbed • More nodes per site, more sites (including US), more users • Evolve architecture and software on the basis of TestBed usage and feedback from users • Closer integration of the software components • Improve software infrastructure toolset and test suites • Look for convergence with PPDG/GriPhyN architecture • Enhance synergy with US via DataTAG-iVDGL and InterGrid • Address shortcomings in plan by collaborating with other EU projects (DataTAG, GridSTART, CrossGrid) • Promote early standards adoption with participation to GGF WGs • Final software release by end of 2003 EU DataGrid
