Participation of Institutions in the HEP Data Grid Project

• Established in July 1, 2000. • A national center

designated by the Korean Ministry of Science and Technology and supported by the Korean Science and Engineering Foundation (KOSEF)

• 47 HEP physicists with doctoral degrees and 120 graduate students from 12 universities inside Korea.

• Major research activities:• CMS at CERN• AMS at ISS based at

CERN• Belle/K2K in Japan• CDF/Phenix in USA

TEIN Bandwidth requirement

– From CERN 100 MB/s experimental data trasfer

– 24 hrs/day, 10 million seconds/year operation

– Data Size =1 PetaBytes/y– MC data production(2 PB/

y) and transfer to Europe and USA

– Therefore we need 2.4 Gbps

• 800 Mbps (Exp Data)• 1600 Mbps (MC Data)

Considering other traffic, we need 10 Gbps.

Korea-Japan (alone) Bandwidth Requirement

KEK Experiments

– 130~370 Mbps by 2006

– 650 Mbps after 2006

Korea-Japan-USA Connection (additional)

– Fermilab CDF Exp. (40~230 Mbps)

– CMS Exp (800 Mbps)

–Total bandwidth requirement:

–1.2~1.6 Gbps Total of minimal 2.4 Gb

ps is required Considering other traffi

c, we need 10 Gbps

Traffic/Data for HEP experiments carried out in Traffic/Data for HEP experiments carried out in JapanJapan 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) amo

ng Korea-Japan collaborators (file transfer)• Therefore, 120 Mbps~360 Mbps is needed (24 hrs/day operation, 25 millions s

econds 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

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) and Run IIb(after 2004 )– 500 Tbytes/year are produced (Run Iia), > 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

– Data Transfer for 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 of Bandwidth requirement Year 2003 2004 2006

SuggestionsSuggestions

Minimal bandwidth requirements for the HEP research is– 2.5 Gbps over Korea-Japan-USA

Suggest that if we use the Busan-Kyushu line for Korea-USA APII, we need the network to be 2.5 Gbps initially and then 10 Gbps at least reflecting other usage in near future.
