National HEP Data Grid Project in Korea Kihyeon Cho Center for High Energy Physics (CHEP) Kyungpook National University CDF CAF & Grid Meeting July 12, 2002

CENTER FOR HIGH ENERGY PHYSICS In Korea, HEP Data Grid Project has started on March Five year project ( ) 30 High Energy Physicists (Ph.D level) from 5 Experiments (CDF, AMS, CMS, K2K, PHENIX) are involved in this project. This project includes to make Asia Regional Data Center (Tier- 1) for CMS, AMS, CDF(?). The center will be located at CHEP, Kyungpook National University. CHEP itself is involved in CDF, Belle, CMS and AMS experiments HEP Data Grid in Korea

CENTER FOR HIGH ENERGY PHYSICS Installed Globus 2.0 on 12 PCs. Constructed Private CA (Certificate Authority). Installed MDS (metacomputing directory service). Installed GridFTP, Replica Catalog, Replica Management. Test the Grid test-bed between CHEP(Tier-1) and SNU(Tier-2) & CHEP and Fermilab. Current Status Data Grid Software and Middleware

CENTER FOR HIGH ENERGY PHYSICS PC clusters will be constructed by at the end of this year. 6 Tbyte HPSS system is supposed to come. Contribute 1 T byte hard disk (now) + 1 T byte hard disk (December) to CDF for the network buffer between CHEP and FCC. On early November, International HEP Data Grid Work Shop will be held at CHEP, Kyungpook National University in Korea. CAF system will be constructed in Korea by Frank’s suggestions. Then, the CAF in Korea and the CAF in FCC will be connected in the future. Any suggestions? Future Plan (This year)
