1 Andrew McNab - Manchester HEP - 22 April 2002 EU DataGrid Testbed EU DataGrid Software releases Testbed 1 Job Lifecycle Authorisation at your site More EDG and TB information

2 Andrew McNab - Manchester HEP - 22 April 2002 EU DataGrid Officially started 1st January 2001 Partners: CERN, CNRS, ESA, INFN, NIKHEF, PPARC Other contributions from HEP institutes (eg in NorduGrid countries) and other Grid projects (eg core UK e-Science) Management and software organised into Work Packages: –WP1 Resource Management (job submission) –WP2 Data Management –WP3 Information and Monitoring Services –WP4 Fabric Management (eg local installation and management tools) –WP5 Mass Storage –WP6 Testbeds (include Integration and support for the Testbed grid.) –WP7 Networking –WP8,9,10 Applications

3 Andrew McNab - Manchester HEP - 22 April 2002 Software Releases Have 3 major releases to coincide with three yearly Testbeds 1, 2 and 3 Have minor releases every 2 months, and then patch level releases between those: currently at (deployed last week) Currently, the only supported platform is RedHat 6.2 on Intel. Software is stored in a central CVS and published via a public HTTP server (http://datagrid.in2p3.fr) in RPM format. This includes EDG-authored software, a distribution of Globus (contributed by GridPP) and any external packages and updates not included in out-of-the-box RedHat 6.2. The official installation procedure is to use LCFG, contributed by Edinburgh and customised by WP4. Once an LCFG server is working at your site, installation of testbed machines is automated (rather like RedHat kickstart.) See Steves talk for details.

5 Authorisation at your site a.k.a how do I maintain the list of certificate names (people) that can use my Testbed site? WP6 provides a standard way of publishing lists of certificate names via an LDAP server, and selecting subsets based on group or Virtual Organisation (eg experiment) affiliation. gridmapdir patch to Globus provides dynamic user account allocation from a pool. Each LHC experiment maintains a VO Server and populates it with the DNs of their members. VOs also exist for WP6, BaBar and GridPP.

6 Andrew McNab - Manchester HEP - 22 April 2002 More information Main EDG site is –each Work Package has a website, usually with documents, mailing list archives etc about its software. WP6 Testbed information at –includes links to software repository, User and Installation Guides, bug tracking Bugzilla etc. UK Testbed support: –has info about mailing list, Steves notes about LCFG and other practical information.

7 Andrew McNab - Manchester HEP - 22 April 2002 Summary EDG producing middleware components as part of a consistent distribution for testbed sites. Situation evolving rapidly, but central aim of job submission to the Grid via a Resource Broker is working. Software available to interested sites, and web and mailing list resources exist for support. See following talks for details.
