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
26/04/2005

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
26/04/2005

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
26/04/2005

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
26/04/2005

10. 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

12. 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
26/04/2005

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
26/04/2005

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
26/04/2005

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
26/04/2005

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
26/04/2005

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
26/04/2005

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
