Tier Structure of GRID Distributed
Computing:
Tier-0/Tier-1/Tier-2
Ian.Bird@cern.ch
Tier-0 (CERN):
• accepts data from the CMS
Online Data Acquisition
and Trigger System
• archives RAW data
• the first pass of
reconstruction and
performs Prompt
Calibration
• data distribution to Tier-1
Tier-1 (11 centers):
• receives a data from the
Tier-0
• data processing (rereconstruction, skimming ,
calibration etc)
• distributes data and MC to
the other Tier-1 and Tier-2
• secure storage and
redistribution for data and
MC
Tier-2 (>200 centers):
• simulation
• user physics analysis

Russian Data Intensive Grid
infrastructure (RDIG)
The Russian consortium RDIG (Russian Data Intensive Grid), was set up in
September 2003 as a national federation in the EGEE project.
Now the RDIG infrastructure comprises 17 Resource Centers with
> 20000 kSI2K CPU and > 4500 TB of disc storage.
RDIG Resource Centres:
– ITEP
– JINR-LCG2 (Dubna)
– RRC-KI
– RU-Moscow-KIAM
– RU-Phys-SPbSU
– RU-Protvino-IHEP
– RU-SPbSU

EGI-InSPIRE
CERN-RFBR project “Grid Monitoring from VO perspective”
Collaboration in the area of WLCG monitoring
WLCG today includes more than 170 computing centers where more than 2 million jobs are
being executed daily and petabytes of data are transferred between sites.
Monitoring of the LHC computing activities and of the health and performance of the
distributed sites and services is a vital condition of the success of the LHC data processing.

JINR –LCG2 Tier2 site
Provides the largest share to the
Russian Data Intensive Grid (RDIG)
contribution to the global
WLCG/EGEE/EGI Grid-infrastructure.
JINR secured 46% of the overall
RDIG computing time contribution
to the solution of LHC tasks
п‚ћ During 2012, CICC has run more
than 7.4 million jobs, the overall
CPU time spent exceeding 152
million hours (in HEPSpec06 units)
п‚ћ Presently, the CICC computing
cluster comprises 2582 64-bit
processors and a data storage
system of 1800 TB total capacity.

WLCG Tier1 center in Russia
• Proposal to create the LCG Tier1 center in Russia (official letter by Minister
of Science and Education of Russia A. Fursenko has been sent to CERN DG R.
Heuer in March 2011).
• The corresponding point to include in the agenda of next 5x5 meeting
Russia-CERN (October 2011)
- for all four experiments ALICE, ATLAS, CMS and LHCb
- ~10% of the summary Tier1 (without CERN) resources
- increase by 30% each year
- draft planning (proposal under discussion) to have prototype in the end
2012, and full resources in 2014 to meet the start of
next working LHC session.

• Discussion about distributed Tier1 in Russia for LHC and FAIR

Joint NRC "Kurchatov Institute" – JINR
Tier1 Computing Centre
Project: В«Creation of the automated system of data processing for
experiments at the Large Hadron Collider (LHC) of Tier1 level and
maintenance of Grid-services for a distributed analysis of these dataВ»
Terms: 2011-2013
Type of project: R&D
Cost: federal budget - 280 million rubles (~8.5 MCHF), extrabudgetary sources - 50%
of the total cost
Leading executor: RRC KI В«Kurchatov instituteВ» for ALICE, ATLAS, and LHC-B
Co-executor: LIT JINR (Dubna) for the CMS experiment
Project goal: creation in Russia of a computer-based system for processing
experimental data received at the LHC and provision of Grid-services
for a subsequent analysis of these data at the distributed centers of the
LHC global Grid- system.
Core of the proposal: development and creation of a working prototype of the firstlevel center for data processing within the LHC experiments with a
resource volume not less than 15% of the required one and a full set
of grid-services for a subsequent distributed analysis of these data.
