INFN – GRID status and activities Cristina Vistoli INFN-CNAF Bologna Workshop di INFN-Grid 25-27 ottobre 2004 Bari

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

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

INFN-GRID partecipation to EGEE EGEE SA1 – infrastructure operation and support ROC – Regional Operation Center CIC - Core Infrastructure Center EGEE JRA1 – IT-CZ cluster Workload management system Resource access –accounting -policy VOMS EGEE NA4/NA2/NA5 HEP application Generic application Dissemination

INFN-GRID partecipation to LCG LHC Computing Grid main sites: T1 and n*T2 LHC Experiments and applications support Operation and deployment of the Grid infrastructure (national and international)

INFN-GRID participation to CoreGRID The CoreGRID Network of Excellence (NoE) aims at strengthening and advancing scientific and technological excellence in the area of Grid and Peer-to-Peer technologies Grid Information and Monitoring Services Knowledge & Data Management

INFN-GRID partecipation to GRID.IT/FIRB Set up the national production grid Infrastructure open to the national research community Grid management and support tools - system First tools in production R&D on Resource Utilization Policies Data Management Scientific Data Base grid integration Middleware porting

INFN-GRID Release INFN-GRID is a customized release of LCG All resources are fully managed via LCFGng; INFN-GRID does not support the middleware installation without LCFGng; INFN-GRID 2.2.0 release is based upon the official LCG-2.2.0 and it is 100% compatible;

INFN-GRID Release Main differences from LCG 2.2.0 to INFN-GRID 2.2.0: Added support for DAG jobs; Added support for AFS on the WorkerNodes; Added support for MPI jobs via home syncronisation with ssh; Documented installation of WNs on a private network; Added full function VOMS support: INFNGRID, CDF are completely managed via VOMS server.

INFN-GRID: Resources and supported VOs (**) Hyperthreaded

CPU versus VO

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

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

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

Ticketing system INFN-GRID ticketing system is used: from users to ask questions or to communicate troubles; from system manager to communicate about common grid tasks (ex: upgrading to a new grid release) from CMT to system manager to notify a problem Support Groups are “helper” groups and they exist to resolve the obvious problems arising with the grow of the grid: Support Grid Services (RB, RLS, VOMS, GridICE, etc) Group; Support VO Services Group (each for every VO); Support VOApplications Group (each for every VO); Support Site Group (each for every site) Operative Groups Operative Central Management Team (CMT); 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
