2. – n° 2 INFN-Grid – goals u Promote computational grid technologies research & development: Middleware and grid tools n Through european and national projects s DataGrid, DataTAG, Firb-GRID-it, EGEE, LCG, CoreGRID etc n Internal R&D activities u Deploy – operate - support INFN grid production infrastructure: Grid as “coordinated resource sharing” on a large scale for a multi-institutional and dynamic virtual organisation u Set up the national production grid Infrastructure open to the national research community n FIRB: Grid.it – astrophysic, geophysic, biomedicine, computational chemistry etc n Reserch community and industry

3. – n° 3 INFN-Grid – goals u Provide operation and support of the EGEE/LCG production infrastructure u Promote dissemination activity to ‘gridify’ scientific applications n GILDA testbed n Genius portal

9. – n° 9 INFN-GRID Release u INFN-GRID is a customized release of LCG n All resources are fully managed via LCFGng; n INFN-GRID does not support the middleware installation without LCFGng; n Change with the next release based on SL3:YAIM and Quattor u INFN-GRID 2.3.0 release is based upon the official LCG-2.3.0 and it is 100% compatible;

10. – n° 10 INFN-GRID Release u Main differences from LCG 2.3.0 to INFN-GRID 2.3.0: n Added support for DAG jobs; n Added support for AFS on the WorkerNodes; n Added support for MPI jobs via home syncronisation with ssh; n Documented installation of WNs on a private network; u Added full function VOMS support: n INFNGRID, CDF are completely managed via VOMS server.

11. – n° 11 INFN-GRID: Resources and supported VOs (**) Hyperthreaded

12. – n° 12 INFN-GRID: Production Grid service Service Resources are open to all VOs supported RB-BDII scope Italian Grid NEW! Resource Broker/UI DAG prod-rb-01.pd.infn.it

13. – n° 13 Grid.IT Production Grid: deployment portal u User documentation u site managers documentation u Software repository u Monitoring u Trouble tickets system u Knowledge base http://grid-it.cnaf.infn.it

14. – n° 14 EGEE/LCG: Production Grid services Service Resources are open to all VOs supported by INFN-GRID and EGEE/LCG RB: egee-rb-01.cnaf.infn.it support BIOMED VO RB-BDII scope all european resources EGEE/LCG RB/UI with DAG

15. – n° 15 Certification activity – TEST ZONE u The Central Management Team is responsible of the resource centers certification: checking the functionalities of a site before joining the site to the production grid. u Although all certification jobs are VO independent, the INFNGRID VO is used to perform these jobs; u In particular are checked: s GIIS' information consistence; s Local jobs submission (LRMS); s Grid submission with Globus (globus-job-run); s Grid submission with the ResorceBroker; s ReplicaManager functionalities; s MPI functionalities u In order to certificate a site the CMT uses dedicated grid services: n RB & BDII: gridit-cert-rb.cnaf.infn.it u In this way we avoid to have an uncertified site in the production grid services;

16. – n° 16 Periodic test u CMT and system managers, could notify advices about their resources via web inserting a “Downtime advices”. u The Calendar shows the snapshot of the Production Service Status. u We periodically submit certification jobs to the sites in order to pro-actively find ‘troubles’ before users find them.

17. – n° 17 Ticketing system u INFN-GRID ticketing system is used: s from users to ask questions or to communicate troubles; s from system manager to communicate about common grid tasks (ex: upgrading to a new grid release) s from CMT to system manager to notify a problem n Support Groups are “helper” groups and they exist to resolve the obvious problems arising with the grow of the grid: n Support Grid Services (RB, RLS, VOMS, GridICE, etc) Group; n Support VO Services Group (each for every VO); n Support VOApplications Group (each for every VO); n Support Site Group (each for every site) n Operative Groups Operative Central Management Team (CMT); n Operative Release & Deployment Team; Users -> Create a ticket Supporters/Operatives -> Open the ticket Users and/or Supporters/Operatives -> Update an open ticket Supporters/Operatives -> Close the ticket
