Operations Coordination Team
Maria Girone, CERN IT-ES
10th October 2012
Update since last GDB
• Operations Coordination Work Group activities have been
kicked-off on 24th September 2012
• Large spectrum of activities to be ensured in operations
– Internal task forces are the driving force and source of specific and
dedicated expertise
– Primary communication channel on operational issues to WLCG
• Regular fortnightly meetings established on 1st and 3rd
Thursdays as main forum
– First Operation Coordination meeting held on 4th October
– Minutes and action list
• Up-to-date twiki at
– https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOpsCoordination

Work in progress
• Most TF’s actively working already. Some highlights from last
meeting’s minutes:
– Upgrade to EMI WN (ideas to install in under CVMFS)
– PerfSonar deployment on priority sites to test priority links
– SHA-2 compliance matrix for middleware in EMI and OSG and setup of a
validation infrastructure. Testing already ongoing
– Discussion on policies and timing for middleware upgrades
– FTS3 deployment co-locate with FTS3 demos. Focus on integration testing
– LHCb has decommissioned Oracle streaming, the local LFCs and oracle
conditions DBs at T1 sites
• Several TF mailing lists created and internal meetings organised
TEG workshop, February 2012
• Operations Coordination is the core WLCG
operations and deployment activity
– Internal Task Forces will need good level of resources
(people) to execute their mandates
– Need more experience on how to operate
• So far better representation from experiments than sites
– Much of the operations activity is site-focused
– Assigning core responsibilities and roles has helped to
raise the profile and participation, but there are many
areas to cover
• Critical components need attention
– Already ongoing activities naturally prioritized. More painful
choices will be needed if effort is missing
