4. 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.

5. 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

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

7. 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

8. 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

9. 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 –Email, 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.

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

11. 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. 4 2003 plans: –10 Gbps backbone. –2.5 Gbps access points.

12. 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
