CMS T2 requirements (before April, 2011)

Basic requirements to CMS VO T2 sites for Physics group hosting: a) info on contact persons responsible for site operation b) site visibility (BDII) c) availability of CMSSW actual version d) regular file transfer test “OK” e) Certified links with CMS T1: 2 up and 4 down f) CMS job robot test “OK” g) disk space ~ 150-200 TB for: - central space (~30 TB) - analysis space (~60-100 TB) - MC space (~20 TB) - local space (~30-60 TB)

- local CMS users space (~2 TB per user) h) CPU resources ~ 3KSI2K per 1 TB disk space, 2GB memory per job

9

T2 readiness requirements

• Site visibility and CMS VO support

• Availability of disk and CPU resources

• Daily SAM availability > 80%

• Daily JR-MM efficiency > 90%

• Commissioned (active) links TO Tier-1 sites ≥ 2

• Commissioned (active) links FROM Tier-1 sites ≥ 4

JINR-KIPT Common Activities in CMS Computing Support

Cooperation between JINR and KIPT (Kharkov, Ukraine) has been supported by 2 grants of Russian Foundation for Basic Research (RFBR) and Ukrainian Academy of Science:

08-07-90410-Ukr_a (2008-2009 гг.) “Preparation of LIT JINR (Dubna) and NSC KIPT (Kharkov) computing centers for CMS (CERN) distributed data analysis on the base of grid technologies” – completed (see: Bunetsky O. O. et al. , Preparation of NSC KIPT and JINR Grid-Infrastructures for Data Analysis at the CMS Experiment (CERN), P11-2010-11, Dubna, 2010, http://www1.jinr.ru/Preprints/2010/011%28P11-2010-11%29.pdf)

10-07-90400-Ukr_а (2010-2011 гг.) “Support and development of LIT JINR and NSC KIPT grid-infrastructures for CMS distributed data processing during the first two years of LHC operation” – in a progress

17

Summary

IHEP, INR, ITEP, JINR, PNPI, SINP and UA_KIPT are in a stable state

RRC_KI – was not in a stable state but by the moment the situation has been significantly improved

Current task is to define status of the RDMS CMS sites in context of the new CMS requirements to CMS T2
