  1. Status and Plans on GRID related activities at KEK Takashi Sasaki Computing Research Center KEK

  2. Main projects at KEK • Proton Synchrotron • particles physics • K2K etc. • KEKB • B physics • BELLE experiment • 300+ members from 54 institutes in10 countries • 4 universities from Taiwan • Photon factory • material science, life science and so on • J-PARC • New facility under construction at Tokai (~2008)  • 3-GeV synchrotron ring, which provides proton beams at 333micoA (1MW) • 50-GeV synchrotron ring, which provides proton beams at 15microA (0.75MW) • particle physics, material science and life science • International collaboration • ATLAS • ZEUS • ILC Takashi.Sasaki@kek.jp

  3. Computing Research Center • Purchase and operation of systems and networking • large scale computing facilities • local, domestic and international network • Research and development on computer hardware, middleware and software • GRID • Geant4 • GRACE • etc. • Still with very limited human resource • only 25 people including secretaries among ~800 employees • outsourcing to companies Takashi.Sasaki@kek.jp

  4. Computer systems at KEK • Systems at Computing Research Center • BELLE • 500TB+ storage • Solaris+PC farm • Central Computer system • IBM SP • HPSS 120TB • Super Computer system • HITACH SR8000 1TFlops • etc. • All of the major systems will be replaced in early 2006 by bidding Takashi.Sasaki@kek.jp

  5. SINET/SuperSINET Connection SuperSINET SINET SuperSINET nodes are connected by DWDM Takashi.Sasaki@kek.jp

  6. GRID related R&D topics ( middleware wise) • Globus • test and deployment since January 2002 • SRB • since 2003 summer with help of SLAC and SDSC • federation among Taiwan, Australia, Korea, China, Poland and Japan • Results of performance measurement and comparison to the NIST Net simulation will be presented by Yoshimi Iida • LCG • collaboration with ICEPP • built the mini-tier0 at KEK Takashi.Sasaki@kek.jp

  7. Certificate Authority • KEK GRID CA • will cover KEK employees and also collaborators just for GRID • hardware and software have been installed and working • CP/CPS is the issue • in preparation with help of ICEPP, U. Tokyo • obtained OID from the government • accreditation of the PMA as soon as possible • ICEPP, U-Tokyo will use this CA for LCG Takashi.Sasaki@kek.jp

  8. BELLE GRID • They have not decided the strategy • Computing Research Center leads the R&D • Distributed analysis and data sharing among institutes • Experimental data distribution to remote sites • 50+ institutes from 10+ countries • Monte Carlo production at remote sites • SRB • A strong candidate of data sharing tool in Belle (we think) • Much tests have been done in collaboration with Computing Research Center and Australia Takashi.Sasaki@kek.jp

  9. Status on SRB deployment • After the last ISGC, we have successfully configured SRB to solve the fire wall issue in the Belle computer system • Workshop for building SRB federation was held in last December at KEK • We have succeeded to make the federation with 3days from the scratch • Some performance measurements have been done • details will be reported by Yoshimi Iida Takashi.Sasaki@kek.jp

  10. SRB zones at KEK • Belle zone • For Belle data distribution • MCAT with Postgres • SONY PetaServe via NFS v3 • Computing Research Center zones • for R&D • MCAT’s with DB2 and Postgres • RAID+HPSS Takashi.Sasaki@kek.jp

  12. Plan on SRB • HPSS enabled SRB server • further performance improvements • GMCat • register files in SRB on LCG RLS • what CMS has been tried before • The GMCat service was written by Simon Metson of Bristol University Takashi.Sasaki@kek.jp

  13. Status and Plan on LCG • LCG server side has been working since last year • HPSS and LCG integration is on-going • SRM for HPSS • towards the mini-tier 0 test • R&D in collaboration with ICEPP • Details are presented in Prof. Sakamoto’s talk • Some of Belle members (non Japanese institutes) have strong interests • they are working for both Belle and one of LHC experiments Takashi.Sasaki@kek.jp

  14. Strategy • Starting from SRB and may migrate to or merge with LCG / EGEE in the future • SRB is good enough for our current requirements and could start very easily and rapidly • We want to hear about progress in LCG and EGEE and we will try to use • Using both in parallel is a option • GMCat may help us • Here, “we” means KEK Computing Research Center • Belle may have their own strategy Takashi.Sasaki@kek.jp

  15. Medical Application • Japanese Geant4 group is working on simulation for particle therapies, such as proton and carbon • dose calculation needs a time and parallel simulation is necessary • need to share clinical data securely among hospitals and computing centers • hospital network system is highly secure • no ports except 80(http) is open • web based solution interfacing with GRID will be developed Takashi.Sasaki@kek.jp

  16. Asia-Pacific Collaboration • Networking • To obtain higher effective bandwidth, need to work at the both end points • Need an opportunity for people who are really working on GRID issue to gather at one place and work together • “real” workshop should be organized • face-face meeting is important for better collaboration • LCG/gLite • many people have interests Takashi.Sasaki@kek.jp

  17. Asia-Pacific Collaboration(2) • SRB • currently Belle has a federation among Taiwan, Korea, China and Australia. • KEK hosts also biological, material and other particle physics programs • Make a federation among sites and realize the data sharing among people who need • SRB feasibility tests and feedback to further developments • SDSC commitment is necessary Takashi.Sasaki@kek.jp

  18. Summary • KEK already have succeed to introduce SRB, Globus and LCG, and they are working • Further development will be necessary • Belle has succeed to make the federation of SRB to replicate and copy files each other • We are watching LCG/EGEE and will try the latest version when it becomes available • Let’s continue to discuss about better collaboration in Asia-Pacific Takashi.Sasaki@kek.jp

  19. Acknowledgements • We really appreciate the organizers of this conference on their efforts and also their warm hospitality Takashi.Sasaki@kek.jp
