INFN – GRID status and activities Cristina Vistoli INFN-CNAF Bologna Workshop di INFN-Grid 25 -27 ottobre 2004 Bari – n° 1

INFN-Grid – goals u Promote computational grid technologies research & development: Middleware and grid tools n Through european and national projects s n Data. Grid, Data. TAG, Firb-GRID-it, EGEE, LCG, Core. GRID etc 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 n FIRB: Grid. it – astrophysic, geophysic, biomedicine, computational chemistry etc Reserch community and industry – n° 2

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 – n° 3

INFN-GRID partecipation to EGEE u EGEE SA 1 – infrastructure operation and support n ROC – Regional Operation Center n CIC - Core Infrastructure Center u EGEE JRA 1 – IT-CZ cluster n Workload management system n Resource access –accounting -policy n VOMS u EGEE NA 4/NA 2/NA 5 n HEP application n Generic application n Dissemination – n° 4

INFN-GRID Release u INFN-GRID n n is a customized release of LCG All resources are fully managed via LCFGng; INFN-GRID does not support the middleware installation without LCFGng; u INFN-GRID 2. 2. 0 release is based upon the official LCG-2. 2. 0 and it is 100% compatible; – n° 9

INFN-GRID Release u Main differences from LCG 2. 2. 0 to INFN-GRID 2. 2. 0: n Added support for DAG jobs; n Added support for AFS on the Worker. Nodes; n n Added support for MPI jobs via home syncronisation with ssh; Documented installation of WNs on a private network; u Added n full function VOMS support: INFNGRID, CDF are completely managed via VOMS server. – n° 10

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

CPU versus VO – 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 – n° 13

Grid. IT Production Grid: deployment portal u u u User documentation site managers documentation Software repository Monitoring Trouble tickets system Knowledge base http: //grid-it. cnaf. infn. it – n° 14

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 – 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 n 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 Resorce. Broker; s Replica. Manager functionalities; s MPI functionalities order to certificate a site the CMT uses dedicated grid services: RB & BDII: gridit-cert-rb. cnaf. infn. it u In this way we avoid to have an uncertified site in the production grid services; – n° 18

Ticketing system u INFN-GRID s s s n 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: n n n ticketing system is used: Support Grid Services (RB, RLS, VOMS, Grid. ICE, 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); 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 – n° 20
