Two Types of Remote CDF Shifts (Remote Control Room) for CDF Experiment

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

US 10G Seoul 5G 5G 10G 20G ChoongBook Inchean 5G 5G Pohang 5G Suwan 5G KyungBook Cheanahn DaeJeon Busan 10G 5G Changwan Junju 10G HK GwnagJu 1G KIX, DACOM IX, KT IX, BIX,6NGIX 2.5G JEJU 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. super computer KISTI has network domestic and global

3. Activities in a “Real” Particle Lab Where e-HEP should focus? 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.

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

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 shifterhas 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. Summary • 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!
