1 European, National and Local INFN GRID projects Leonardo Merola Dipartimento di Scienze Fisiche - Università di Napoli Federico II Istituto Nazionale di Fisica Nucleare - Sezione di Napoli International Workshop Engineering the GRID San Leucio (CE), 30 Maggio 2003 International Workshop Engineering the GRID San Leucio (CE), 30 Maggio 2003

2 (1 m)( m)(< m)( m) ( m)( m) (< m) is the public Institute that promotes, coordinates and developes experimental and theoretical fundamental research in nuclear and sub-nuclear physics. In particular, it searches for the elementary building blocks of the Matter and studies the laws of their fundamental interactions.

7 Network Connectivity

8 INFN GRID project (started in 1999): development of computing infrastructures for physics, based on GARR (the Italian Academic and Research Network). DataGrid EU FP5 project ( ): A milestone towards a common European Research Area (ERA) prototyping the European Grid infrastructure. INFN is contributing in various areas of grid middelware development, especially in the production of brokering and scheduling services with Datamat S.p.A, in the monitoring and the grid activities and, together with Nice s.r.l., in the development of theWeb portal GENIUS (Grid Enabled web eNvironment for site Independent User Job submission). INFN Condor Pool (started in 1997): more than 300 CPUs in a pre-GRID High Throughput Computing solution to distributed computing on WAN.

9 DataTag EU FP5 project ( ): DataTag EU FP5 project ( ): (Trans Atlantic Grid) project aims at prototyping a fast transatlantic optical network connection supporting grid activities and at developing interoperability between the grids in Europe and USA. It focuses on problems related to the transfer Protocols, reliability in the use and integration of the middleware. EU-US Global Laboratory Universal Environment The EU-US Global Laboratory Universal Environment (GLUE) activity, jointly developed by DataTag (EU) and iVDGL (US), will enable CERN, INFN and other European, American and Asian Laboratories to create the first world grid; it will be dedicated to High Energy Physics (HEP). LCG LHC Computing Grid (LCG) project ( ): LHC Computing Grid (LCG) project ( ): approved by the CERN Council in 2001 to help the experiments computing projects prepare, build and operate the computing environment needed to manage and analyze the data coming from the detectors. INFN deeply involved in all 4 experiments(ATLAS, CMS, ALICE, LHCb).
