GRID related RD 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

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

8
BELLE GRID

• They have not decided the strategy
• Computing Research Center leads the RD
• 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

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

10
SRB zones at KEK

• Belle zone
• For Belle data distribution
• MCAT with Postgres
• SONY PetaServe via NFS v3
• Computing Research Center zones
• for RD
• MCATs with DB2 and Postgres
• RAIDHPSS

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

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
• RD in collaboration with ICEPP
• Details are presented in Prof. Sakamotos talk
• Some of Belle members (non Japanese institutes)
  have strong interests
• they are working for both Belle and one of LHC
  experiments

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

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

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

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

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
• Lets continue to discuss about better
  collaboration in Asia-Pacific

  conference on their efforts and also their warm
  hospitality
