2. TB1 integration from site admins We (spanish Testbed sites) are one of the EU-DataGrid “remote” (as described in D6.1) Testbed sites –Not yet in the Testbed1 Here, I will briefly report on our activities on the Testbed1up to now and try to extract some “Testbed site needs” from this experience

3. Status of the spanish Testbed sites IFAE (Barcelona) - AC, Proj. coord.

4. Status of the spanish Testbed sites IFAE (Barcelona) - AC, Proj. coord. IFCA (Santander) - Spanish CA IFIC (Valencia) CIEMAT (Madrid) Funded effort distribution for the 1st year

9. Testbed1 activity Try to “stay tuned” within the information flow: –Documentation Key document – EDG Installation Guide Other documents in the WP6 Web page –Bugzilla Keep an eye on it to be aware of bug status Use it to report about malfunction discovery –Mailing lists, specially… www.listbox.cern.ch/earchive/hep-proj-grid-integration-team/ + Real-time info -

10. Testbed1 activity Try to “stay tuned” within the information flow: –Documentation Key document – EDG Installation Guide Other documents in the WP6 Web page –Bugzilla Keep an eye on it to be aware of bug status Use it to report about malfunction discovery –Mailing lists, specially… www.listbox.cern.ch/earchive/hep-proj-grid-integration-team/ General comment: Up to now it has been quite hard for a “remote site” to follow the Testbed1 evolution from those sources “We are shooting on a moving target” (F. Gagliardi)

11. TB info sources: EDG Install Guide The EDG Installation Guide Main source of information It is an “evolving document” (current from 3/02/2002) –It is “condemned” to be incomplete http://www.pi.infn.it/~flavia/se_config.html http://www.lnl.infn.it/datagrid/wp4-install/testbed-report_2/index.html Sometimes the info is a bit confusing or inconsistent w.r.t. other WP’s docs –E.g. Configuration of the CE & SE Info Systems…

12. TB info sources: EDG Install Guide E.g. Configuration of the CE&SE Info Systems: Examples of info-mds.conf are given twice –7.5(7.6) CE(SE) Configuration, Configuring GRAM and GRIS –8.1 Ftree&MDS Info Services and Info Providers For the parameters inside globus.conf: –From WP3 Web (http://hepwww.rl.ac.uk/DataGridMonitoring)http://hepwww.rl.ac.uk/DataGridMonitoring GRID_INFO_GRIS_REG_GIIS=ral - The site name GRID_INFO_GRIS_REG_HOST=hostname.rl.ac.uk –From WP3 Document “MDS Deployment Testbed-1” GRID_INFO_GIIS_1=tb1-pbs GRID_INFO_REG_GIIS_1=ral GRID_INFO_REG_HOST_1=hostname.rl.ac.uk –From EDG Installation Guide GRID_INFO_GIIS_1=ce - The GIIS name GRID_INFO_REG_GIIS=ral - The site name GRID_INFO__REG_HOST=hostname.rl.ac.uk

13. TB info sources: Bugzilla & mailing list Bugzilla (http://marianne.in2p3.fr/datagrid/bugzilla)http://marianne.in2p3.fr/datagrid/bugzilla Keeps record of s/w features/bugs Information about which are the open/closed problems at a given moment Searchable: Clear classification in terms of programs (GDMP, LCFG…) and versions New category “Testbed configuration” added on mid December: –This might be the best info repository for site admin issues –Still, some information here is not totally up to date…

14. TB info sources: Bugzilla & mailing list The ITeam mailing list www.listbox.cern.ch/earchive/hep-proj-grid-integration-team/ This is the ultimate source of truly real-time information concerning TB1 installation issues –E.g. Replica Catalog installation instructions, SE/GDMP configuration issues… The throughput is high enough (~10 2 mails/day) to make online reading/filtering a tough task Searchable: But not as good as bugzilla to search for “all those problems related to a given service”

15. MapCenter Online information about LDAP based Information Systems User friendly browsable

16. More info sources: WP6 secure Web http://marianne.in2p3.fr/ Extensive info on real TB machines config. rpm -qa/ps -ef output.conf files …

17. More info sources: National WP6 Web sites All them accessible from marianne.in2p3.fr Several (Dutchgrid, Nordugrid, GridPP,…) include useful information on the EDG s/w installation & configuration: –Step-by-step instructions for installing services –Comments on the “official” installation procedures –… –Some really fancy monitoring information…

18. More info sources: MDS monitoring MDS single-host response times from dutchgrid.nl web

19. Summary ( what we need/have from WP6?) Bugzilla “Testbed Configuration” category Site administrators mailing list WP7 monitoring tools such as MapCenter Configuration of some “reference” machines (CERN?) available from a secure Web site EDG Installation Guide: collect all the useful information that is dispersed Useful info on national WP6 web sites (tools, step- by-step installations…) could be compiled somewhere Planning & schedule for widespread TB deployment to remote sites
