  1. LCG Deployment in Japan Hiroshi Sakamoto ICEPP, Univ. of Tokyo

  2. Contents • Present status of LCG deployment • LCG Tier2 • Certification authority • Implementation • Recent topics • KEK-ICEPP joint R&D program • Network • Upgrade of resources • Future plan

  3. LCG in Japan • Tier2 center at ICEPP, U. Tokyo • Decision made in October 2004 • Man power consideration • A few dedicated people • Including engineers and outsourcing • Contribution to LHC/ATLAS • The size of community ~ 4% of ATLAS • Want to contribute more

  4. Japanese CA for HENP • KEK-CA is ready for operation • Japanese HENP society ~ KEK users • LHC ATLAS • KEK-B Belle • JPARC (50GeV PS at Tokai) • RHIC Phenix (RIKEN) • CP/CPS prepared • Discussion between KEK and ICEPP • To be submitted to the EU Grid PMA • Or to the AP Grid PMA?

  5. TOKYO-LCG2 cluster • LCG-2 cluster@u-tokyo • 52 Worker Nodes • Upgraded to LCG-2_3_1 (last week) • From LCG-2_1_1 last week • With YAIM • Redhad 7.3 (will replace Scientific Linux)

  6. PC Farm • HP ProLiant BL20p • Xeon 2.8GHz 2CPU/node • 1GB memory • SCSI 36GBx2, hardware RAID1 • 3 GbE NIC • iLO remote administration tool • 8 blades/ Enclosure(6U) • Total 108 blades(216 CPUs) in 3 racks

  10. R&D Menu • Stand-alone grid connecting two clusters • 1Gbps dedicated connection between KEK and ICEPP (SuperSINET) • Exercises understanding LCG middleware • Special interests • SRB • Grid datafarm (Osamu Tatebe AIST)

  11. Network • Peer to peer 1Gbps between CERN and ICEPP • Sustained data transfer study • 10Gbps to US and EU • Still thin, but improving connection among Asia/Pacific countries • JP-TW to 1Gbps very soon. • JP-HK, JP-CN
