APROC Usage I I • Jobs predominately from Biomed, CMS and Atlas VOs • Past year: 41 KSI2K Years • This April: 21 KSI2K Years 13
APROC Availability I • Ideal Grid World: May 3, 2006 14
APROC Availability I I • Daily snapshots of SFT results of each site • Availability of 60-70% • Better if weighted with numbers of CPU • CT mostly replica management failure • Sensitive to Information System performance • Network Issues • Network congestion and packet loss • APROC SmokePing to monitor net performance • But monitoring from CERN is more relevant • Scheduled Downtime • Network and power maintenance Decommissioned • Hardware maintenance and upgrade Slow BDI I • Middleware upgrade 2.4 2.6 2.7 100% 100% 90% 90% 80% 80% SD 70% 70% CT CT 60% 60% JL 50% JL 50% JS 40% 40% JS OK 30% 30% OK 20% 20% 10% 10% 0% 0% 2005-04 2005-06 2005-08 2005-10 2005-12 2006-02 2006-04 4 5 6 7 8 9 0 1 2 1 2 3 4 0 0 0 0 0 0 1 1 1 0 0 0 0 - - - - - - - - - - - - - 5 5 5 5 5 5 5 5 5 6 6 6 6 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 2 2 2 2 2 2 2 2 2 15
Support I ssues and Tickets Statistic (Total/Monthly Avg) • Remote troubleshooting • Email interaction is slow Open tickets 10 • Remote testing is limited Close tickets 425/39 • Reluctantly ask for access Total tickets 435/40 to services • Local diagnostic tools would be helpful 16

Agenda • Introduction • ROC Status • Recent Activities 18
Security Service Challenge 1 • Purpose to ensure that: • Sufficient information is available for audit trace (for IR) • Appropriate communication channels are available • Security Challenge with (OSCT) • Sending test jobs • Sites recover evidence • DN of job submitter IP address of submission UI • Executable name Time when executable ran • Results • Completed March 2006 for a period of one week • Instructions and audit guide sent to participating sites • 4 of 7 APROC sites completed challenge • Some sites could not participate due to SD or unavailability • Some results were incomplete since sites did not have Resource Broker (RB) • Sites need to contact RB admin for more information • Helpful learning exercise to familiarize security contacts with auditing process for LCG • Improvements • Sharing of audit techniques between ROCs (GOCWiki) • Tools to extract security audit information • Helpful for future SSC to measure security patch response time 19
Pre-Production Service • APROC started PPS service in April 2006 • Previously managed by Application team • PPS deployment with glite-3.0 RC2 complete • Mix of LCG and gLite components • LCG-CE gLite-CE • MON combined UI • Integration of production SE and SRM services • FTS still needs to be deployed • Summary • Good way to get experience with gLite middleware • Using YAIM is very good transition for ROC staff • LCG components are more stable than gLite counterparts • Required significant support from CERN for gLite-CE • Integration with lcg-CE batch system was not trivial • Still troubleshooting • Need significant time to relearn administration and troubleshooting techniques • Administration documentation like ones accumulated for LCG in GOCWiki would be helpful 20
Grid Administrator Tutorial I • Goal and details • Educate and train EGEE Site Administrators • Two day tutorial with instruction in Chinese • Hosted at Academia Sinica in March 2006 • Topics covered • Grid technology and components • Operations, administration and troubleshooting • Brief overview of Grid applications • Hands-on session to deploy functional sites • 36 Xen servers configured • Simple CA, RB, BDII, VOMS, LFC provided • 5 teams of 6 participants deployed sites (UI, MON, CE, WN, DPM-head, DPM-disk) • Based on Marco La Rosa’s KEK tutorial • http://lists.grid.sinica.edu.tw/apwiki/Grid_Administrator_Tutorial_Hands-on_Instructions 21
Grid Administrator Tutorial I I • Results • 30 participants from 15 institutes • 4.18/5.0 survey evaluation scores • Only a couple teams where able to complete a fully functional site • Not enough time • Setup YAIM configuration from scratch • Time consuming and error prone • More realistic and gives chance for participants to troubleshoot • Feedback • Break up hands-on session to practice after each lecture • Provide a reference cheat sheet • Acronyms • Grid architecture diagrams • Suggest Linux training material as prerequisite • Provide user and developer tutorials • Significant time to setup hands-on session servers for installation • Is this available in GLIDA? 22
GStat Development • Instances created for • PPS Service • Regional projects • balticGrid, EELA, • EUChinaGrid, etc.. • Usage calculations modified • PhysicalCPU • SizeTotal, SizeFree • Results published • To Service Availability Monitoring Environment (SAME) at CERN • Client tool for to retrieve historical data • http://goc.grid.sinica.edu.tw/gocwiki/GStat_Client_Tools 23
