13. VO for the Belle Experiment Belle VO is federated among 4 countries, 6 institutes, 9 sites. Belle VO is federated among 4 countries, 6 institutes, 9 sites. – Japan: Nagoya University and KEK – Taiwan: ASGC and NCU – Australia: University of Melborne – Poland: CYFRONET – Korea University comes up soon. Started using SRB and LCG Started using SRB and LCG Data distribution service using SRB-DSI Data distribution service using SRB-DSI – Belle already has a few PBs data in total including 100s TB DST and MC Bulk file register helps us: Sregister Bulk file register helps us: Sregister we do not move any of them we do not move any of them – It is too much difficult to export existing data to LCG physically – Benefits both for native SRB users and LCG users SRB-DSI with LCG is in operation now. SRB-DSI with LCG is in operation now. 2007/6/13Grid Operations Workshop at KTH, Stockholm13 CYFRONETPolandCYFRONETPoland KEKJapanKEKJapan Nagoya Univ. Japan Japan Melbourne Univ.

15. Hiroshima IT VO for the Accelerator Science Domestic supports Domestic supports – Typical case at laboratory: A few staffs, ~10 students and no technician. Start to monitor them centrally over the VO Start to monitor them centrally over the VO – Focused on their operation supports – Not only for WLCG sites but also for NON-WLCG sites – PPJ VO is started for the accelerator science in Japan. – Federated among a few universities. Tohoku Univ., Tsukuba Univ., Kobe Univ., Hiroshima Univ., Nagoya Univ. and KEK. – Usage: To share resources and experiences among major groups, ILC, KamLand, CDF and ATLAS without depending on experimental projects. 2007/6/13Grid Operations Workshop at KTH, Stockholm15

16. Conclusion Tools used in daily grid operations Tools used in daily grid operations – Semi –automatic installation tools only for WNs Most of tools are handmade scripts Most of tools are handmade scripts – Monitoring tools, e.g.; SAM and GSTAT are very useful. – GGUS Search and APWIKI are also. – We are testing to audit by using nCircle, vulnerability management system. Scheduled Interventions Scheduled Interventions – 11 times in JFY2006 – Due to Software/hardware upgrade and site reconfiguration Software/hardware upgrade and site reconfiguration Annual maintenance Annual maintenance Replacement of host certificate Replacement of host certificate Unscheduled interventions Unscheduled interventions – ~10 times/year – Ex) Failed to reconfigure the site, or power cut by thunder. Domestic supports in Japan Domestic supports in Japan – Important mission for KEK. ~90% of problems are detected by the COD, SAM, GSTAT and nagios. ~90% of problems are detected by the COD, SAM, GSTAT and nagios. – Our operation on Grid is supported by great efforts by APROC members in ASGC, Taiwan. – We’d like to keep the tighter collaboration with ASGC. 2007/6/1316Grid Operations Workshop at KTH, Stockholm
