October 9, 2001Francesco Forti, Italy Report3 HEP Organization in Italy 4 Two main players. –Universities, through physics departments. –INFN, centrally managed with local “sections.” 4 INFN. –Provides most of the funding and technical resources. 4 Universities. –Provide a lot of personnel, buildings, students.

October 9, 2001Francesco Forti, Italy Report4 INFN Geography 4 INFN is present in all major Italian universities. 4 INFN scientific structure: I.Accelerator HEP. II.Non-accelerator HEP. III.Nuclear physics. IV.Theoretical physics. V.Accelerators, R&D and interdisciplinary physics. 4 INFN groups participate to almost every HEP experiments in the world. Nat’l Labs Sections Groups

October 9, 2001Francesco Forti, Italy Report5 INFN Computing Structure 4 Complex interaction between various aspects: –Computing for the experiments –Basic, computing services (from to SAN) –INFN intranet and wide area network connections –Grid

October 9, 2001Francesco Forti, Italy Report6 Scientific Computing 4 Discussed and funded in the national scientific committees 4 Develops around regional centers Experiment specific farms Tier structure –Babar: Tier A –Virgo: Tier 1 –LHC: 1x Tier 1 and 10-15x Tier 2 Existing Planned

October 9, 2001Francesco Forti, Italy Report7 Planned investement 4 Preliminary plan –Babar Tier A in Padova –Virgo Tier 1 in Pisa –LHC prototype Tier 1 in Bologna/CNAF See Ruggieri’s presentation at June HEP-CCC

October 9, 2001Francesco Forti, Italy Report8 Local computing services 4 Coordinated by National Computing Committee (Chair M. Mazzuccato) 4 Run by small groups of professionals, using common strategies and tools – , web services, AFS, printing, DNS, OS installation and maintenance, videoconf., disks, tape libraries, application sw, router configuration, backup, etc. etc. 4 INFN wide recipes and contracts simplify the work.

October 9, 2001Francesco Forti, Italy Report9 Working Groups 4 Several working groups exists to solve common problems. Security. . Linux distribution. Tools: printing and backup tools. LDAP. Windows (NICE, now 2000). AFS, DFS. Videoconference. Condor. What can be outsourced ? European collaboration when possible

October 9, 2001Francesco Forti, Italy Report10 Networking 4 WAN based on 155Mbps university research backbone. –INFN is the initiator of the GARR project. –Network outsourced up to the PoP. 4 Pilot GARR-G project has an already operation 2.5Gbps backbone plans: –10 Gbps backbone. –2.5 Gbps access points.

October 9, 2001Francesco Forti, Italy Report11 Conclusions INFN is moving fast into the 21 st century computing. Interplay between scientifical and technical committees/discussions Strong GRID activity, good network Need to reduce the amount of work for everyday’s computing tasks: More standardization Pre-cooked solutions and recipes Outsourcing
