Online and Offline Remote Data Handling at KISTI for FNAL CDF Experiments • KISTI e-Science HEP • Online Remote Data Handling – CDF Control Room – KISTI Remote Control Room • Offline Remote Data Handling – CDF Data Handling Overview – CDF SAM Shift Details

KISTI e-Science HEP Virtual Laboratory HEP based on e-Science ⇒ e-HEP (High Energy Physics) “Whenever, Wherever Same Environment as Real Lab” Data Production – Online: Remote Control Room – Offline: SAM Data Handling Data Processing – Data Center Data Publication – Enabling Virtual Organization Build a “Virtual HEP Lab” by expanding a “real HEP Lab” via e-HEP!

Online Remote Data Handling At KISTI High Energy Physics Group For Korean CDF Collaborators

CDF Control Room @ Batavia, IL Fermilab CDF Control Room consists of several components, one of which is CO (Consumer Operator) CDF’s Main Control Room Monitoring Section

Everything at CDF CO Section is available at Remote Site

Setup at KISTI RCR (2) (3) (4) (1) Windows 4 displays Monitoring (2) Windows 4 displays Monitoring (3) Linux (4) Polycom 2 displays Kerberized for concon Communication Server

Concon Forwarding to KISTI • DOE Security Policy – Remote site can not execute commands. • Have to rely on port forwarding feature of SSH in kerberized connection

Brief History CDF Remote CO KISTI 3 remote control room for CDF - Pisa, Tsukuba and KISTI

First Real Remote CO Shift by Professor K. K. Joo(Aug. 1 – Aug. 8)

Offline Remote Data Handling • • Another type of remote data handling Called CDF SAM Data Handling SAM : Sequential Access thru Metadata Offline data are monitored and manipulated

CDF DH Elements Fermilab Mass Storage System • enstore – In-house, manages files, tape volumes, tape libraries – End-user direct interface to files on tape • d. Cache – Joint DESY and Fermilab, disk caching front-end – End user interface to read cached files, write files to enstore indirectly via d. Cache • pnfs – DESY file namespace server (nfs interface) used by both enstore and d. Cache

CDF Data Handling Overview

CDF SAM Data Handling Shift • Mostly by Offsite Remote Collaborators – Hyunwoo KIM(KISTI) since last Nov. • CDF SAM/DH Group – Led by Angela Bellavance – Shift Crew consist of ~10 persons • Relevant Group – The d. Cache/enstore group of FNAL CD – CAF (CDF Analysis Farm) Group

CDF DH At A Glance (1) • Health of SAM Stations in CAF and Farm • Monitor SAM data transfers in upload server

CDF DH At A Glance (2) • Monitor data transfers in and out of d. Cache: cells, doors, and pools

CDF DH At A Glance (3) • Monitor data transfer in and out of enstore: movers and tapes

EVO Use in CDF SAM DH Shift

Summary • KISTI has successfully implemented two e-Science components for HEP – Remote Shifts for both online monitoring CO and offline SAM Data Handling. • These two are cornerstones for KISTI to establish e-Science for High Energy Physics.
