HEP Data Grid Development
 Final goal of the Korean HEP Data Grid is the Tier-1 Regional
Data Center of LHC-CMS experiment in Asia and this can be
also used as regional data center for many other experiments
(Belle, CDF, AMS, etc.)
 Korean HEP Data Grid Working Group was formed under the
auspices of the Grid Forum Korea (GFK) in October 2001
 A proposal of the Korean HEP Data Grid has been submitted to
the Ministry of Information and Communication March 16, 2002
 It is approved by KISTI / MIC on March 22, 2002 and in progress
now
o 210 Mwons(ca. US$168k) in 2002
 National Computerization Agency (NCA) supports CHEP with
two international networking utilization projects for HEP both of
which are related to HEP Data Grid : Europe and Japan/USA
o 287 Mwons total (ca. US$230k) in 2002
HEP Data Grid Development
KNU and SNU host one EDG testbed each
and are running at a fundamental level (July
2002)
o Application of the EDG testbed to currently running
experiments: Configuration
 EDG testbed for CDF data analysis
 EDG testbed for K2K data analysis
 EDG testbed for CMS data analysis
CHEP is discussing with iVDGL collaboration
(since August 2002)

Bandwidth Requirements for HEP
•
•
•
Belle Experiment
– At present, data of 30 Tbytes/year are being collected: 0.3 TB/day
• It is approxmately 5~15 Mbytes/s, meaning 40 ~120 Mbps
• Production and share of Monte Carlo simulated data (~3 times of real
data) among Korea-Japan collaborators (file transfer)
• Therefore, 120 Mbps~360 Mbps is needed (24 hrs/day operation, 25
millions seconds in total operation per year)
– After 2006, we expect collecting data at 220GHz amounting 2 PB data/year
• Koreans expect processing 30% of data (600 TB/year)  4800 Tb/30
Ms = 160 Mbps
• Monte Carlo data production and share with Japan (approx 1.8 PB/year)
 480 Mbps
• Therefore, we need 640 Mbps between Japan-Korea for this
experiment
K2K Experiment
– Until 2001, we have approx. 830 GB of unprocessed data
– Processed data size is 3.1 TB
– Expect the same size of data in 2003
– Monte Carlo Simulation Data is about 1.6TB
– We need 2~3 Mbps
SuperKamiokande(Super-K) Experiment (Kamioka-near Toyama)
– Collects approx. 27 Gbytes of data, needs 8*27 Gb/86.4 ks = 2.2 Mbps
– About the same size of Monte Carlo data are produced
– We need 5~6 Mbps
Bandwidth Requirements for HEP (continues)
•
Summary for Korea-Japan connection
– 130~370 Mbps by 2006
– 650 Mbps after 2006
•
When Genkai is extended to USA via Korea-Japan
– CDF Experiment at Fermilab
• Run IIa(2001.3 - 2004)
500 Tbytes/year
• and Run IIb(after 2004 ) > 3 Pbytes (after 2004)
• Before 2004 : 10% processing (50 TBytes/year) : ~ 13 Mbps
• After 2004 : 10% processing (300 TBytes/year) : ~ 76 Mbps
• Monte Carlo Data Production and Transfer: twice the above
• Before 2004 : 40 Mbps
• After 2004 : 230 Mbps
– CMS (Europe)
• Monte Carlo Data Production and share with USA CMS Collaborators
• 15 years from 2003, we share 1 Petabytes/year = 800 Mbps is needed

Summary & Network Activities ( 2003 )
 Excellent network supports from APAN(-KR)
o Domestic KOREN/KREONET are the Advanced Network for
Research
 To be upgraded to GbE (6 sites) with 40 Gbps backbone
o APII for Korea-US via KREONET (45 Mbps310 Mbps)
o Korea-US : 10Gbps  IEEAF link
( Link & Access Committee in APAN-KR is working )
o TEIN for Korea-Europe to be upgraded to > 45 Mbps  GbE
or 10 Gbps?
o APII for Korea-Japan (now 8 Mbps)  64~155 Mbps
 Or expect GbE (2 Gbps) with the Hyeonhae/Genkai Project APII
 So far the HEP Data Grid project has gotten excellent
supports from MIC/KISTI/NCA/KOREN-NOC and
KT/IBM-Korea/CIES, etc.
Summary & Network Activities ( 2003 )
 HEP Data Grid is considered for most of Korean
participating HEP experiments
 Domestic HEP Data Grid is now in progress and in very
good collaboration internationally with Europe/US/
Japan counterparts
 Grid technologies are deployed in establishing testbeds
for EU Data Grid and the Korean HEP will be
collaborating with iVDGL as well as CMS MC production
team
 Minimal bandwidth requirements for the HEP research
is
o 2.5 Gbps over Korea-Japan-USA, 2.5 Gbps over
Korea-Europe
