1. Two Types of Remote CDF Shifts (Remote Control Room) for CDF Experiment 김현우 CDF Korea Workshop, Daejeon APRIL 17 2008

2. The Goal of KISTI e-Science-HEP To construct a virtual particle laboratory !! Virtual Laboratory enables us to research as if we were on-site. Virtual Laboratory is built on top of e- Science infrastructure. 10G 10G HK US 10G 5G 5G 5G 10G 5G 5G 20G 5G 5G 2.5G KIX, DACOM IX, KT IX, BIX,6NGIX 1G Busan Pohang KyungBook Changwan GwnagJu Junju DaeJeonCheanahn Inchean SuwanSuwanSuwanSuwan ChoongBook Seoul JEJU super computer KISTI has network domestic and global

3. Data Production Data Processing Data Publication The e-HEP tries to enable us to conduct the same 3 real data phases in a virtual particle physics laboratory. Activities in a “Real” Particle Lab Where e-HEP should focus?

4. Data Production: CDF@KISTI Remote Operation Center Fermilab CDF Control Room consists of several components, one of which is CO Monitoring Section CDF’s Main Control Room CDF data taking in a more convenient way

5. Data Production : CDF@KISTI Remote Operation Center KISTI CDF ROC will be used by Korean CDF researchers when they are short on travel fund and have more shifts to take! Only 2 out of 63 CDF institutes operate remote CDF monitoring control room. KISTI will be the third!

6. Current Status of KISTI RCR Concon Stability Test between KISTI and CDF Control Room conducted during my visit to FNAL last week. Test Shift scheduled during one of Korean CO shift at CDF Then we will be real ready to perform the remote CO shift. The first person to take a remote CDF CO shift will be…

7. What a Remote CO shifter has to do Be qualified to be a CO shifter Come to KISTI at Daejeon Other requirements are fulfilled by KISTI- CDF group already.. –Prerequisite agreement with CDF shift coordinators

8. CDF SAM Data Handling Shifts Remote Collaborators can join! –Hyunwoo KIM with KISTI since last Nov. CDF SAM/DH Group –Led by Angela Bellavance –Shift Crew consist of ~10 persons Relevant Group –The dCache/enstore group of FNAL CD –CAF (CDF Analysis Farm) Group

9. SAM/DH Shift Details From Tuesday 9 AM Local Time To Next Monday 6 PM Local Time Each Shift 8 Hours: 9 AM to 6 PM Short discussion with the leader (A. Bellavance) over EVO (CDF DH Ops) Report in FNAL CD Tuesday SAM Meeting

10. SAM/DH Shift Coverage I SAM Job sources e/f SAM Web Browser –SAM stations for CAF –SAM Stations for FARM Two types of SAM jobs –File Upload: Upload Servers –File Retrieve (Read from tapes) Various Relevant Servers –Database Servers –Name Servers –Web Servers

11. SAM/DH Shift Coverage II SAM requests are passed eventually to enstore via dCache –Doors: User Interface –Diskpools: Buffer Zones Read: Read from a pool Restore: Read from a tape and write to a pool Raw, Read, Stage, ReadOnly, B, Test

12. SAM/DH Shift Coverage III Enstore Two Libraries, Movers and Tapes CDF-9940B with 18 movers CDF-LTO3 with 15 movers 7 Types of Data Categories Raw, Farm, SAM Upload, General Read, Stage Read and B Physics Read

13. Korean EVO Servers at KISTI Besides general HEP uses, KISTI uses EVO for bot RCR and SAM shifts!!

14. KISTI HEP Group Activities ⇒ Build a virtual laboratory –CDF@KISTI RCR (2008. 4 예정 ) –EVO servers as collaboration tools Two Types of Remote CDF Shifts –CO shifts in KISTI Remote Control Room –CDF SAM Data Handling shifts High energy physics is leading Korean e- Science program! Summary
