Report on availability of the JINR networking, computing and information infrastructure for real data taking and processing in LHC experiments Ivanov V.V. Laboratory of Information Technologies Programme Advisory Committee for Particle Physics 31st meeting, 10–11 June 2009

Development of the JINR Grid-environment The formation of a unified Grid- environment of the JINR Member States is a basis of the 7-year plan within the direction “Networks. Computing. Computation al Physics”. Three main levels within the Grid- environment : network, resource and applied.

Frames for Grid cooperation of JINR in 2009 Worldwide LHC Computing Grid (WLCG); Enabling Grids for E-sciencE (EGEE); RDIG Development (Project of FASI) CERN-RFBR project “GRID Monitoring from VO perspective” BMBF grant “Development of the GRID-infrastructure and tools to provide joint investigations performed with participation of JINR and German research centers’ “Development of Grid segment for the LHC experiments” was supported in frames of JINR-South Africa cooperation agreement; NATO project "DREAMS-ASIA“ (Development of gRid EnAbling technology in Medicine&Science for Central ASIA); JINR-Romania cooperation Hulubei-Meshcheryakov programme Project "SKIF-GRID" (Program of Belarussian-Russian Union State). Project GridNNN (National Nanotechnological Net) We work in close cooperation and provide support to our partners in Armenia, Belarus, Bulgaria, Czech Republic, Georgia, Germany, Poland, Romania, South Africa, Ukraine, Uzbekistan.

RDIG obligations to WLCG

VO disks usage June 2009

Resource usage (real time statistics, 8 June 2009)

LHC experiments jobs (from December 2008 to June 2009

Normalised CPU time for RDIG VO (January – 8 June 2009)

Normalised CPU time at RDIG-sites for CMS, ATLAS and ALICE VO (January – 8 June 2009)

ALICECMSATLAS

External monitoring from WLCG

At the beginning of June starts STEP’09 which is a multi-VO exercise in frames of WLCG. The acronym stands for Scale Testing for the Experiment Program in Results of this testing (CMS and ATLAS) will be available at the end of June

Conclusion The high-speed 20 Gbps telecommunication data link Dubna – Moscow was installed. The availability of the applied technologies and state-of-art networking equipment will be used for further extension of the channel capacity. The LIT plans on increasing the CICC performance up to 2300 KSI2K and the data storage up to 400 TB have been completed. The optimization of the network infrastructure of the JINR Central Information and Computing Complex was performed. The JINR CICC infrastructure testing in frames of the preparation of real data processing for LHC experiments is in progress now.

Thank you for your attention !
