  6. GridRelated Services • We have our own GRID CA • is started on Feb. 2006, and is recognized by LCG. • is accredited by APGRID PMA • http://gridca.kek.jp/ • VO Membership Service • Supported VOs: • apdg is the VO for Asia-Pacific Data Grid. • belle is the VO for Belle experiments. • atlasj is the VO for Atlas experiments in Japan. • g4med is the VO for Geant4 medical application. • PPJ is the VO for the Particle Physics in Japan. • ail is the VO for Associated International Laboratory between Japan and France. • http://voms.kek.jp/ • Local Mirror Service • SL, SLC, LCG, gLite • It takes ~30 minutes to update by using apt-get with CERN or FNAL repositories. • ~3 minutes with KEK repository • http://hepdg.cc.kek.jp/mirror/ • Semi-automatic Installation Service • WNs can be installed semi-automatically by PXE (Preboot eXecution Environment) and kickstart configuration file. • http://hepdg.cc.kek.jp/install/ • Site Portal • http://grid.kek.jp/ Grid Operations Workshop at KTH, Stockholm

  7. People on Grid at KEK/CRC • 7 persons in total • CA • T. Sasaki and Y. Iida • VOMS • Y. Watase and G. Iwai • Site Operation and Security • KEK-0 • G. Iwai • KEK-1 • T. Sasaki, Y. Iida, Y. Watase and G. Iwai • KEK-2 • T. Sasaki, Y. Watase, and G. Iwai • Deployment • Y. Watase, Y. Iida and G. Iwai • Documentation • Y. Watase • Networking • S. Suzuki, S. Yashiro and Y. Iida • Application (SRB, Portal and some Gridified applications) • K. Murakami, Y. Iida and G. Iwai Grid Operations Workshop at KTH, Stockholm

  8. OPERATION STATISTICS Grid Operations Workshop at KTH, Stockholm

  9. Submitted GGUS Tickets in JFY2006 • Total number of submitted ticket: 28 • KEK-1: 11 • KEK-2: 17 Grid Operations Workshop at KTH, Stockholm

  10. Number of Submitted Jobs in JFY2006 JP-KEK-CRC-01 JP-KEK-CRC-02 Grid Operations Workshop at KTH, Stockholm

  11. Normalized CPU time in JFY2006(kSI2K*hrs) JP-KEK-CRC-01 JP-KEK-CRC-02 Grid Operations Workshop at KTH, Stockholm

  12. Belle Experiment and Accelerator Science VIRTUAL ORGANIZATION Grid Operations Workshop at KTH, Stockholm

  13. VO for the Belle Experiment • 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 • 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 • 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.

  15. VO for the Accelerator Science • Domestic supports • Typical case at laboratory: A few staffs, ~10 students and no technician. • 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. Hiroshima IT Grid Operations Workshop at KTH, Stockholm

  16. Conclusion • Tools used in daily grid operations • Semi –automatic installation tools only for WNs • 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 • 11 times in JFY2006 • Due to • Software/hardware upgrade and site reconfiguration • Annual maintenance • Replacement of host certificate • Unscheduled interventions • ~10 times/year • Ex) Failed to reconfigure the site, or power cut by thunder. • Domestic supports in Japan • Important mission for KEK. • ~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.

  19. Points to Cover in Each Presentation • tools used in daily grid operations • what features are missing to make your work easier • examples of the most frequent scheduled interventions at your site • examples of the most frequent unscheduled interventions at your site • points to improve in communication with ROC, other sites, Vos, rest of the world... • How do you plan deployment of updates/new versions so continuous production is not interrupted? • Communication with users: how are you informed about operational problems at your site reported by local/remote users? Mail/GGUS/phone/other? • Correlation of cross-site issues: is the operations meeting enough for this? How do you do it otherwise? • What percentage of real site problems are detected and reported by the COD before you know about them? • usefulness of the following operations bodies/meetings and suggestions to improve them: • COD • your ROC support team • operations meeting Grid Operations Workshop at KTH, Stockholm
