Future prospect of KEK CC

• Tier-0 for Belle-II (2014~ ?)– Tier-1 centers in Asia, Europe, Americas

• What if Super-KEKB and Super-B merges ?

• Tier-1 or 2 for SLHC (20xx~) ?– Needs discussion with ICEPP and ATLAS-J

• Continue R&D– GRID, GEANT4, GRACE, DAQ,…

Global link

• Asian accelerator network– G5 (China, India, Korea, Japan, Russia)

• Launched last December on the DG’s initiative

• Link to Europe through FxPPL (x=c,j,k,v)• Why not “geographical enlargement” of FJPPL

– Start with computing centers; • CCIN2P3-KEK-KISTI-GRIDKA

– Then invite other countries
