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

  2. HEP Data Grid in Korea HEP Data Grid in Korea • In Korea, HEP Data Grid Project has started on March 2002. • Five year project (2002-2006) • 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

  3. Experiments for HEP Data Grid Project in Korea Space Station (AMS) US FNAL (CDF) USBNL (PHENIX) EuropeCERN (CMS) Korea CHEP JapanKEK (K2K)

  4. Project (2002-2006) Final Goal • Networking • Multi-leveled hierarchy (both for data and for computation) • Network Services • Videoconferencing • OO Database access • Data Storage Capability in Data Center • Storage : 1100 TB Raid Type Disk • Tape Drive : 60 Tape Drives of IBM 6590 • TSM Server/HPSS : 3Pbyte • Computing powers (1000 CPUs) • Need both centralized and distributed linux clusters • Parallel computing and parallel storage capability

  5. Project (2002-2006) 3 PBytes storage Supercomputers Commodity PCs 1000 CPUs Processing Fabric LANs Sundomang National network Gbit Networks The Goal of HEP Data Grid Network (1) Connection Data Grid abroad • Between CERN(Tier-0) and CHEP(Tier-1), Korea : Gbps network • Between Fermilab, USA and CHEP(Tier-1), Korea : APII : 1 Gbps • Between KEK, Japan and CHEP(Tier-1), Korea : APII and Hyunhae : 1 Gbps (2) Domestic Data Grid • Between CHEP(Tier-1) and Tier 2 : 155 Mbps ~ 1 Gbps • Between CHEP(Tier-1) and Other : 45 ~ 155 Mbps

  6. Project (2002-2006) USA ESNET (Fermilab, BNL) JAPAN AP II or APAN-ESNET China(IHEP) 1Gbps CHEP TEIN-155 (CERN, DESY) Using KOREN Topology Or HPCNET/Kreonet Topology

  7. Current Status (As of July 12, 2002) • CPU : 40 CPU (1.7 GHz) Clusters • HDD • about 3 Tbyte (80 GB IDE X 40) • 100Gbyte Raid + 600 Gbyte Tape library • Network CHEP ----- KNU ---- Sundomang ---- Star tap ---- Fermilab 1Gbps 1 Gbps 45Mbps ? • The actual network performance between CHEP and FNAL is 3~5 Mbps (30~50 Gbyte/day). Hardware

  8. Current Status PC Clusters By the end of this year, a PC cluster of total 100 CPUs will be constructed.

  9. Current Status Data Grid Software and Middleware • Installed Globus 2.0 on 12 PCs. (10 @CHEP, 1@SNU, 1@Fermilab) • 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.

  10. Future Plan (This year) • 100 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?
