  7. Goals of Russian (distributed) Tier2 • to provide a full-scale participation of Russian physicists in the analysis • only in this case Russian investments in LHC would lead to the final goal of obtaining a new fundamental knowledge on the structure of matter • to open wide possibilities for participation of students and young scientists in research at LHC • support and improve a high level of scientific schools in Russia • participation in the creation of international LHC Computing GRID will mean for Russia an access to new advanced computingtechniques

  8. Functions of Russian (distributed) Tier2 • physical analysis of AOD (Analysis Object Data); • access to (external) ESD/RAW and SIM data bases • for preparing necessary (local) AOD sets; • replication of AOD sets from Tier1/Tier2 grid (cloud); • event simulation • at the level of 5-10% of the whole SIM data bases for each experiment; • replication and store of 5-10% of ESD • required for testing the procedures of the AOD creation; • storage of data produced by users.  participation in distributed storage of full ESD data (Tier1 function)…?

  9. Architecture of Russian (distributed) Tier2 • RRC-LHC will be a cluster of institutional centers with Tier2 functionality • distributed system - DataGrid cloud of Tier2(/Tier3) centers • a coherent interaction of computing centers of participating Institutes: • each Institute knows its resources but can get significantly more if others agree; • for each Collaboration summary resources (of about 4-5 basic institutional centers) will reach the level of 50-70% of a canonical Tier1 center: • each Collaboration knows its summary resources but can get significantly more if other Collaborations agree; • RRC-LHC will be connected to Tier1 at CERN and/or to other Tier(s)1 in a context of a global grid for data store and access: • each Institute and each Collaboration can get significantly more if other reg.centers agree.

  10. The opportunity of Grid technology JINR IHEP RRC KI SINP MSU PNPI ITEP Russian Regional Center: theDataGrid cloud LCG Tier1/Tier2 cloud FZK CERN GRID access … Gbits/s RRC-LHC Tier2 cluster Regional connectivity: cloud backbone – Gbit’s/s to labs – 100–1000 Mbit/s Collaborative centers

  11. “Users”-“Tasks” and resources(analysis from 2001 – need to be updated – conception of Tier2s) The number of active users is main parameter for estimation of the resources needed. We did some estimates, in particular based on extrapolation of Tevatron analysis tasks performed by our physicists (single top production at D0, …). Thus, in some “averaging” figures: an “user task” – analysis of 107events per a day (8 hours) by one physicist ALICEATLASCMSLHCb 40606040 Very poor understanding of this key (for Tier2) characteristics! In the following we estimate RRC resources (Phase 1) by the assumption that our participation in SIMdata base production is at 5% level for each experiment.

  12. Resources required by the 2008 • We suppose: • each active user will create local AOD sets ~10 times per year, and keep these sets on the disks during the year • the general AOD sets will be replicated from the Tier1 cloud ~10 times per year, storing previous sets on the tapes. • The disk space usage will be partitioned as • 15% to store general AOD+TAG sets; • 15% to store local sets of AOD+TAG; • 15% to store users data; • 15% to store current sets of sim.data (SIM-AOD, partially SIM-ESD); • 30-35% to store the 10% portion of ESD; • 5-10% cache.

  13. Construction timeline Timeline for the RRC-LHC resources at the construction phase: After 2008 investments will be necessary for supporting the computing and storage facilities and increasing the CPU power and storage space. In 2008 about 30% of the expenses in 2008. Every next year: renewing of 1/3 of CPU, increase the disk space for 50%, and increase the tape storage space for 100%.

  14. Financial aspects • Phase1 (2001-2005) • 2.5 MCHF equipment, 3.5 MCHF network • + initial inivestments • to some regional networks • Construction phase (2006-2008) • 10 MCHF equipment, 3 MCHF network • _____________________________________ • in total (2001-2008) 19 MCHF • 2009 – 200x 2 MCHF/year 2003, December – new Protocol has been signed by Russia and CERN on frameworks for Russia participation in LHC project on period from 2007, including: 1) M&O, 2) computing in Exps, 3) RRC-LHC and LCG.

  19. Russia in LCG • We have started activity in LCG in autumn 2002. • Russia joined to the LCG-1 infrastructure (CERN press-release 29.09.2003). First SINP MSU, soon RRC KI, JINR, ITEP and IHEP (already to LHC-2). • http://goc.grid-support.ac.uk/gridsite/gocmain/monitoring/ • Manpower contribution to LCG (started in May 2003): • the Agreement is under signing by CERN and Russia and JINR officials, • 3 tasks for our responsibility: • 1) testing new GRID mw to be used in LCG • 2) evaluation of new-on-the-market GRID mw (first task – evaluation of OGSA/GT3) • 3) common solutions for event generators (event data bases) • Twice per year (spring-autumn) meetings of the Russia-CERN Joint Working Group on Computing. Next meeting on 19 March at CERN.

  22. It was designed andrealized OGSA/GT3 testbed (named 'Beryllium') on the basis of PCs located at CERN andSINPMSU modelling a GT3 based Gridsystem. http://lcg.web.cern.ch/LCG/PEB/GTA/LCG_GTA_OGSA.htm Created software for common library of MC generators, GENSER, http://lcgapp.cern.ch/project/simu/generator/ New project MCDB (Monte Carlo Data Base) for LCG AA is proposed with Russia responsibility, as common solution for storing and providing access cross the LCG sites to the samples of events at partonic level.

  23. The simplified schema of Beryllium testbed (CERN-SINP) • The resource broker plays a central role: • Accepts requests from the User • Using the Information Service information, selects the suitable computer elements • Reserve the selected Computing Element • Communicates to the user a “ticket” to allow job submission • Maintains a list of all jobs running and receive confirmation • messages of the ongoing processing from the CEs • At job end, it updates the table of running job/CE status

  27. EGEE Enabling Grids for e-Science in Europe – EGEE • EU project approved to provide partial funding for operation of a general e-Science grid in Europe, including the supply of suitable middleware. EGEE is proposed as a project funded by the European Union under contract IST-2003-508833. Budget – about 32 Meuro per 2004-2005. • EGEE provides funding for 70 partners, large majority of which have strong HEP ties. • Russia: 8 institutes (SINP MSU, JINR, ITEP, IHEP, RRC KI, PNPI, KIAM RAS, IMPB RAS), budget 1 Meuro per 2004-2005 • Russian matching of the EC budget is in good shape (!)

  28. EGEE Partner Federations • Integrate regional Grid efforts
