Tier-1 CMS Center at JINR

On the proposal of the Ministry of Science and Education of the
Russian Federation in 2011, The CICC was established and in March 2015 a full-scale Tier-1 Center at  JINR: T1_RU_JINR.
This center is intended for long-term storage of experimental and
simulated CMS experiment data.

As of  2019, the Tier-1 center consists of

Batch System , type Slurm

Storage  Systems : 

Disk arrays Only 10.4 PB (buffer 1.1 PB)
– long-term data storage on tapes – the IBM TS3500 tape robot is
11 PB
EOS   4PB
( For VOs: NICA (MPD, B@MN, SPD), Baikal-GDV, ER)
– CVMFS 
2 machines: 2x70TB h/w RAID1 (VOs: NICA (MPD, B@MN, SPD).

Software :

  • The Torque 4.2.10/Maui 3.3.2 software (custom-built) is used as a resource manager and a task scheduler.

  • The PhEDEx software is used as a tool for management of the CMS data placement.

The standard WLCG program stack such as

  • 2 x CREAM,

  • 4 x ARGUS,

  • BDII top, BDII site,

  • APEL parsers, APEL publisher,

  • EMI-UI, 220 x EMI-WN + gLExec-wn,

  • 4 x FTS3,

  • LFC,

  • WMS,

  • L & B,

  • glite-proxyrenewal

    is used for data processing.

The service support system provides

  • the operation of a computing service,

  • a data storage service,

  • a grid service,

  • a data transfer service (FTS – File Transfer System),

  • a distributed computing management system (Torque) and

  • an information service (monitoring of services, servers, storage, data transmission, information sites).

The CMS Tier1 centre at JINR has demonstrated stable work through the entire period since its launch into full operation . Since the beginning of 2019, 637,208,434 tasks have been completed, which accounts for 18% of the Sum CPU Work (HS06 hours) of CMS experiment data processed by all Tier1 centres.
