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

2. 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

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

4. 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

5. 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)

6. 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

9. 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 release is based upon the official LCG and it is 100% compatible;

10. 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.

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

12. CPU versus VO

13. 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

14. Grid.IT Production Grid: deployment portal
User documentation
site managers documentation
Software repository
Monitoring
Trouble tickets system
Knowledge base

15. 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

16. 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;

17. 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
