Construction Experience and Application of Construction Experience and Application of the HEP DataGrid in Koreathe HEP DataGrid in Korea
Near Future Experiments AMS / ISS (MIT, NASA, CERN) :
Y2005 CMS (CERN, Europe) : Y2007 Linear Collider Experiment(s)
Development of Korean HEP Data GridDevelopment of Korean HEP Data Grid Grid Forum Korea (GFK)’s formed in 2001 and thus KHEPDGWG started Korean HEP Data Grid approved by KISTI / MIC(GFK) on March 22, 2002. NCA supports CHEP with two international networking utilization projects
which are closely related with the Korean HEP Data Grid : Europe and Japan/USA Networking
KT/KOREN-NOC supports CHEP with PC clusters for networking Companies like IBM-Korea, CIES agreed to support CHEP 50TB Tape
Library and 1TB +Servers) INDUSTRY CHEP itself supports HEP Data Grid with its own research fund from the
Ministry of Science and Technology (MOST) MOST and CHEP Kyungpook Nat’l Univ. supports CHEP with spaces for the KHEPDGWG KOREN/APAN supports Korean HEP DG with 1 Gbps bandwidth of CHEP
to KOREN (2002) networking (one is CHEP and the other is in Seoul) is under discussion Hyeonhae/Genkai APII (GbE) for HEP (beteewn Korea-Japan) project is
in progress 1st International HEP Data Grid Workshop in Nov 2002
Goals of Korean HEP Data GridGoals of Korean HEP Data Grid Implementation of the Tier-1 Regional Data Center for the LHC-CMS
(CERN) experiment in Asia. The Regional Data Center can be also used as regional data center for other experiments (Belle, CDF, AMS, etc.)
Networking Multi-leveled (Tier) hierarchy of distributed servers (both for data and
for computation) to provide transparent access to both raw and derived data.
Tier0 (CERN) – Tier1 (CHEP) : ~Gbps via TEIN Tier1(CEHP) – Tier1(US and Japan) : ~Gbps via APII/Hyeonhae Tier-1 (CHEP), Tier-2 or 3 (participating institutions): 45Mbps ~ 1
Gbps via KOREN
Computing(1000 CPU Linux clusters)
Data Storage Capability Storage 1.1 PB Raid Type Disk (Tier1+Tier2) Tape Drive ~ 3.2 PB HPSS Servers
Software: Contribute to grid application package development
Korean HEP Data GridKorean HEP Data GridNetwork Configuration (2002)Network Configuration (2002)
Network Bandwidth between institutions CHEP-KOREN: 1 Gbps (ready to Users) SNU-KOREN: 1Gbps ready for test CHEP-SNU: 1Gbps ready for test SKKU-KOREN: 155 Mbps (not yet to Users) Yonsei-KOREN: 155 Mbps (not yet to Users)
CHEP started discussing on collaboration with iVDGL SNU/KNU implemented an application of the EUDG testbed f
or the CDF and the implementation is working Network test is performed between Korea-US, Korea-Japan,
Korea-EU, and within Korea. 1st Internatonal HEP DataGrid workshop held at CHEP
Prospects of KHEPDGWG for Y2003Prospects of KHEPDGWG for Y2003 More testbed setup (e.g., iVDGL’s WorldGrid) Extend application of EDG testbed with currently
running experiments to, e.g., Belle
Cross Grid Tests between EDG – iVDGL in Korea
Investigate possibility of Globus3 Full operation of HPSS (HSM) with Grid Softwares Increase number of clusters to 400 CPU or more Increase Storages to 100 TB Participate in the CMS data challenge 2nd HEP DataGrid Workshop will be held in August
SummarySummary
HEP Data Grid is being considered for most of Korean HEP institutions
So far the HEP Data Grid project has received excellent supports from government, industry, and research institutions
EDG testbeds and its application are operational in Korea, and we will expand with other testbeds, e.g., iVDGL WorldGrid
1st international workshop on HEP Data Grid was held successfully in November 2002
CHEP will host 2nd international workshop on HEP Data Grid in August 2003
