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

Main projects at KEK Proton Synchrotron KEKB Photon factory J-PARC 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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

SRB zones at KEK Belle zone Computing Research Center zones 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 26/04/2005

Plan on SRB HPSS enabled SRB server GMCat 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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005

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 26/04/2005
