16. 2.5. Power and Cooling at KEK Comp. Research Center Max. power consumption and Cooling capacity for each machine room: Problem: Budget reduction of 1% /year for the computer resource is critical. Legacy air conditioners remain many. Less cooling efficiency, but are too expensive to replace them at a time. Electric power of 2MW consumed by computers etc. has not been crucially discussed at KEK, but will be a big problem soon.

Beginning of FY2009 : T2K will start the experiment. End of FY2008: B Factory Experiment will be terminated. After 3 or 4 years for the Machine upgrade, a higher luminosity B experiment will start. FY2012? Before 2008 summer : LHC will start the colliding beam experiment. Unified unified 3.1. Future Plans at KEK

18. Computer Systems Jan.2006 : Nuclear Phys. Computer System was unified to the Central Information System Jan.2009 : Central Information System Upgrade Photon Factory Computer System will be unified to this system This system will support the J-PARC project. Feb.2012 : The contracts of following systems will be terminated. B Factory Computer System (Mar.2006 ～ Feb.2012) Next Central Information System (Feb. 2009 ～ Jan. 2012) KEK will become LHC Tier1 Center in the long run. When and How are under debate.
