1. 27-28 August 2002Flavia Donno, INFN-Pisa1 Report on GLUE activities Flavia Donno, INFN-Pisa EDG Retreat 27-28 August 2002

2. Flavia Donno, INFN-Pisa2 Summary  Resource Discovery and GLUE schema  Authorization services from VO LDAP to VOMS  Common software deployment procedures  IST2002 and SC2002 joint EU-US demos Interoperability : between Grid domains for core grid services, coexistence of optimization/collective services

3. 27-28 August 2002Flavia Donno, INFN-Pisa3 Resource Discovery and GLUE schema Computing Resources Structure Description Entry point into queueing system Container grouping subcluster or nodes Homogeneous collection of nodes Physical computing nodes

4. 27-28 August 2002Flavia Donno, INFN-Pisa4 Resource Discovery and GLUE schema CE Schema implementation status  Logical structure seems to have reached agreement and is stable  Recently added file system, versioning  Interoperability: EDG needs one CE working on a cluster made of a single Subcluster  Information about Hardware are in the subcluster  Information about Queue Status are in the CE  Information providers have to provide Subcluster and CE info  LDAP implementation defined, agreed and released!  Glue Schema will be included in Globus MDS 2.2 (September 15 th )  Globus Info Providers fill the host level info  EDG Info providers filling Subcluster and CE are needed !! When ? Is the 31 st of August confirmed ?  It might be necessary to include the EDG info providers in VDT  This implementation can be tested with MDS 2.1

5. 27-28 August 2002Flavia Donno, INFN-Pisa5 SE Schema implementation status  Logical structure almost agreed  Missing agreement on how to model connection between storage services and file system  LDAP prototype implementation set up  Questions to EDG for release 2: Do we need to model multiple instances of Storage Service on an SE ? Multiple VO etc... Could it be possible to remove the SE concept and introduce the 'storage services' insisting on the same hardware or 'Storage Device‘? Resource Discovery and GLUE schema

8. 27-28 August 2002Flavia Donno, INFN-Pisa8 Resource Discovery and GLUE schema GLUE Schema testbed on-going activity Cnaf/Bologna site status - GIIS vo=Datatag edt004.cnaf.infn.it SE v0.1 - EDG 1.1.14, MDS 2.1 Glue Schema CE v1.0, Glue Schema SE v0.1 upgrade to edg1.2 - GRIS grid006f.cnaf.infn.it - EDG 1.1.14, MDS 2.1 Glue Schema CE v1.0 - Upgrade to edg 1.2 - LDAP test (no EDG software, no Globus) gummo.cnaf.infn.it - Glue Schema CE v1.0, Glue Schema SE v0.1 - Configure RB EDG 1.2 in edt003.cnaf.infn.it - Modify the RB to query the Glue Schema - Install EDG/WP4 Information Provider - Install SE EDG 1.2 and Glue Schema SE v0.1

9. 27-28 August 2002Flavia Donno, INFN-Pisa9 Resource Discovery and GLUE schema GLUE Schema testbed on-going activity  US side: Top level GIIS with Glue schema CE v1.0 GRIS with Glue Schema CE v1.0 and MDS 2.1 and static info provider to be upgraded to MDS 2.2 and Globus Info Provider Node with Glue Schema for SE ready for testing.

10. 27-28 August 2002Flavia Donno, INFN-Pisa10 R-GMA implementation and interoperability with MDS  The Glue UML model is general and can have different implementations: LDAP, Relational DB, XML etc.  Schema implementation in R-GMA : implement the Glue UML model in R-GMA and test in the Glue testbed, with EDG WP3 adapt the info providers to fill the the relational table, this should be zero or very low impact Does MDS need to interoperate with R-GMA ?

20. 27-28 August 2002Flavia Donno, INFN-Pisa20 Joint EU-US grid demos  GLUE testbed with Common GLUE schema and authorization/authentication tools.  EDG 1.2 + extensions, VDT 1.1.3 + extensions  “Old” authentication/authorization tools : VO LDAP servers, mkgridmap, etc.  We rely on the availability of the new GLUE schema, RB and Information Providers  Concentrate on visualization: CMS/GENIUS, ATLAS/GRAPPA, EDG/MAPCENTER (EDG/WP7), Farm Monitoring tools (EDG/WP4), iVDGL/GANGLIA, DataTAG/NAGIOS  Use WEB portals for job submission (CMS/Genius, ATLAS/Grappa)  Provide a World Map of the sites involved (EDG-WP7/MapCenter, DataTAG/Nagios)  Monitor job status and statistics (EDG-WP4, DataTAG/Nagios). In Nagios implemented “top users”, “top applications”, “total resources”, “averages over time”, “per VO”,…  Monitor farms (EDG/WP4, DataTAG/Nagios)  Developing plugins/sensors for WP1/L&B info (only on EDG part)  Services Monitoring (EDG/WP4, DataTAG/Nagios [using MDS info])  CMS and ATLAS demo  ATLAS simulation jobs, GRAPPA modified to use both RB or explicit resources  Pythia & CMSIM simulation jobs submitted to intercontinental resources with IMPALA/BOSS interfaced to VDT/MOP, EDG/JDL, Genius portal.  Definition of the application demos in progress.

21. 27-28 August 2002Flavia Donno, INFN-Pisa21 Joint EU-US grid demos

22. 27-28 August 2002Flavia Donno, INFN-Pisa22 Joint EU-US grid demos Joint Task force in Chicago 23-30 September, 2002 for first DataTAG/iVDGL and ATLAS rehearsal. Work on infrastructure and application demos as much as possible before the middle of September. First simple sumission tests in progress. Hardware definition in progress.

23. 27-28 August 2002Flavia Donno, INFN-Pisa23 Suggestions to EDG for release 2 Work on installation/configuration issues Relocatability Configuration environemnt Service configuration and startup Make sure “vanilla functionality” of core services is kept. Security system with VO support Information System Submission services such as the Globus Gatekeeper, JobManager, Condor-G,... Schedule with time introduction of GLUE components in EDG. Active collaboration. Make service interfaces clear so to allow for easy software sharing and integration whenever possible. Discuss architecture design for Job scheduling, Data Management and Storage Services....
