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 (20 xx~) ? – Needs discussion with ICEPP and ATLAS-J • Continue R&D – GRID, GEANT 4, GRACE, DAQ, …

ICEPP Tape Robot PC Servers Disk Arrays ~270 m 2 ATLAS Tier 2 Disk Arrays

Global link • Asian accelerator network – G 5 (China, India, Korea, Japan, Russia) • Launched last December on the DG’s initiative • Link to Europe through Fx. PPL (x=c, j, k, v) • Why not “geographical enlargement” of FJPPL – Start with computing centers; • CCIN 2 P 3 -KEK-KISTI-GRIDKA – Then invite other countries
