9Russia in LCGhttp//www.cern.ch/lcg
- We have started activity in LCG (LHC Computing
GRID project) in autumn 2002. - Russia is joining to the LCG-1 infrastructure
now. First SINP MSU, then JINR, ITEP and IHEP. - Goal to have in Russia in Q4 operational
segment of world-wide LCG infrastructure and be
ready to DataChallenges in 2004. - 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 GT3 and
WebSphere) - 3) common solutions for event generators
(event data bases).

11LCG - Goals
- The goal of the LCG project is to prototype and
deploy the computing environment for the LHC
experiments - Two phases
- Phase 1 2002 2005
- Build a service prototype, based on existing grid
middleware - Gain experience in running a production grid
service - Produce the TDR for the final system
- Phase 2 2006 2008
- Build and commission the initial LHC computing
environment
- LCG is not a development project
- it relies on other grid projects for grid
middleware development and support

16- Distribution of GRID Service Activities over
Europe - Operations Management at CERN
- Core Infrastructure Centres (CICs) in the UK,
France, Italy, Russia and at CERN, responsible
for managing the overall Grid infrastructure - Regional Operations Centres (ROCs), responsible
for coordinating regional resources, regional
deployment and support of services.
