rutier2 cluster
RuTier2 Cluster
  • Conception:

    • operating for all four experiments - ALICE, ATLAS, CMS and LHCb
  • Basic functions:analysis; simulations; users data support
  • plus some Tier1 functions

Participating institutes:

Moscow ITEP, SINP MSU, RRC KI, LPI, MEPhI…

Moscow region JINR, IHEP, INR RAS

St.Petersburg PNPI, SPbSU

Novosibirsk BINP

rutier2 status wlcg mou
RuTier2 status – WLCG MoU

Financing Agencies:

Federal Agency on Science and Innovations (FASI)

Joint Institute for Nuclear Research (JINR)

Tier2 Facilities to install in Russia for ALICE, ATLAS, CMS and LHCb

Russia and JINR representatives in C-RRB:

Yu.F. Kozlov (FASI) and V.I. Savrin (SINP MSU) for Russia

A.N. Sisakian for JINR

Representatives in WLCG Collaboration Board:

V.A. Ilyin (SINP MSU), alternative V.V. Korenkov (JINR)

  • WLCG MoU has been delivered to FASI in February 2006.
  • official approval in Russia in progress (now to agree with Ministry of Finance)
  • relevant Annexes are prepared (for 2006 corrections are coming)
    • A6.4 (Computing Capacities – CPU, Disk, Tape, WAN),
    • A6.5 (Russia as one of the WLCG Operations Centers),
    • A6.6 (manpower contribution to common WLCG software)
rutier2 planning

Preliminary summary computing capacities year by year

for computing facilities (worked out in the beginning 2005):

RuTier2 planning

To be corrected

rutier2 to the lcg start

Time milestones for the equipment installation:

RuTier2 to the LCG start

Understanding to

the spring 2006:

  • 2006:
  • FASI budget for equipment about 1.7 MEuro (not confirmed yet)

about 30% smaller than requested;

  • JINR budget is not known yet;
  • plus additional money from internal sources of participating institutes (SINP MSU, RRC KI, PNPI, ITEP and IHEP, …)

The equipment status for this year:

  • the budget to be fixed/known to July-August 2006;
  • to install in autumn 2006, available for experiments in the end of 2006
  • already clear that:

no tapes, 1500 KSI2K CPU and 600 TB Disk (25% reduction)

  • could be further reduction …

2007-2011: budget planning – about 2 MEuro per year for equipment

rutier2 in the world wide grid
RuTier2 in the World-Wide Grid

RuTier2 Computing Facilities is operated by Russian Data-Intensive Grid (RDIG), we are creating as Russian segment of the European grid infrastructure EGEE http://www.egee-rdig.ru

Final draft of

WLCG MoU:

  • RuTier2 sites (institutes) are RDIG-EGEE Resource Centers
  • Basic grid services are provided by RRC KI, SINP MSU, and JINR
  • Operational functions are provided by IHEP, ITEP, PNPI and JINR
  • Regional Certificate Authority and security are supported by RRC KI
  • User support (Call Center, link to GGUS in FZK) - ITEP

RDIG budget (about 1 MEuro per year)

2005-2006:

by EU FP6 EGEE (EGEE-II) ~ 50%

by FASI (two grid technological projects) and by Rosatom ~ 50%

2007-2008:

EGEE-II Contract has been signed recently by EU FP6

FASI and Rosatom budget is under constructive approval

rutier2 contribution to lcg common software
RuTier2: contribution to LCG common software

Contribution to the development of grid middleware and application software for common use by WLCG and Experiments.

LCG 1st Phase contribution by Russia and JINR: 3 FTE

WLCG MoU: Russia 2 FTE, JINR 1 FTE.

  • Tasks:
    • Contributions of Experiments to ARDA
    • Testing of new MW (SA3 activity, partly by CERN-INTAS)
    • Development of new MW (basically within new CERN-INTAS)
    • CASTOR - development of massive data storage software
    • PH/GENSER – library of MC event generators grid enabled
    • PH/MCDB – MC events data bases grid enabled

Visiting budget on 2006-…: Russia 2 FTE approved,

JINR 1 FTE approved.

international connectivity
International Connectivity

International connectivity for Russian science are based today on

622 Mbps link to GEANT2 (2.5 Gbps from autumn 2006)

Moscow (RASNet) – Frankfurt (GEANT2)

5~10~20 Mbyte/s achieved for LCG data transfer in first experiments within Service Challenge activity (SINP, JINR, ITEP)

Another channel, within link 2.5 Gigabit/s Moscow - St-Perersburg – Stockholm operated by RUNNet and then to Amsterdam (SURFNet) operated by RBNet (GLORIAD) is available for us too.

Now – to test these links for SC4 needs (started with Kors Bos)

Connectivity with USA, China, Japan and Korea LCG partners through the GLORIAD:

622 Mbps Chicago-Amsterdam-St-Petersburg-Moscow

155 Mbps Moscow – Novosibirsk – Khabarovsk – Beijing

Plans: 2006 622 Mbps – 1 Gbps, 2007 1-2.5-10 Gbps

GÉANT2 Topology (Oct. 2005)

November 2005:

GEANT2

Point-of-Presence

opened in Moscow

2x622++ Mbps

regional connectivity

Moscow 1 Gbps (ITEP, RRC KI, SINP MSU, …LPI, MEPhI),

IHEP (Protvino) 100 Mbps fiber-optic (plans to have 1 Gigabit/s)

JINR (Dubna) 1 Gbps f/o (from December 2005)

PNPI (Gatchina) 1 Gbps f/o for LCG (2 Mbps commodity Internet)

BINP (Novosibirsk) 45-100 Mbps (GLORIAD++)

INR RAS (Troitsk) 10 Mbps commodity Internet,

new f/o project to start!

SPbSU (S-Peterburg) 1 Gbps (?)

REGIONAL CONNECTIVITY

1 Gbps f/o

  • Our pragmatic goal to 2007:
    • all RuTier2 sites to have at least 100 Mbps f/o

dedicated for network provision of RDIG users,

    • 1 Gbps dedicated connectivity between basic RDIG

sites and 1 Gbps connectivity to EGEE via GEANT2/GLORIAD.

Current status of LHCb in Russia

Russian distributed Tier-2 cluster permanently

participates in LHCb activities (~35% of CPU in Russia)

Computing centers:

IHEP (Protvino), INR (Troitsk), ITEP (Moscow),

PNPI (St.Petersburg), SINP MSU (Moscow), JINR (Dubna)

Massive MC production (Data Challenges) – became

a routine task, going on with a minimal intervention from

site managers (via LCG resources or in pure DIRAC mode)
