email@example.com Weekly OSG, EGEE, WLCG infrastructure coordination meeting.
We discuss the weekly running of the production grid infrastructure based on weekly reports from the attendees. The reported issues are discussed, assigned to the relevant teams, followed up and escalated when needed. The meeting is also the forum for the sites to get a summary of the weekly WLCG activities and plans

CMS has finished 3 of of 4 mid-week Global Run exercises, as planned. They are 1,5 days long exercises. From the computing standpoint, it has been a valuable set of exercise to check the full T0 workflow, also on (relatively) recently deployed components, from P5 down to transfers of the data to T1 sites, with custodiality also. We plan to run a CRUZET-4 cosmic run exercise in the time slot August, 18th-25th, most probably continuing after that with magnetic field on. From the computing standpoint, and from the support and shifting experience, we are trying to use these exercises to get prepared to a season of constant data flow.
Problems found: some network at P5 issues, some DB-related interventions and issues, all properly documented and discussed with CERN-IT in several fora already. Progress can be done on identified areas, work is being done especially in the communication flows, and CRUZET-4 will be a chance to test for several days in a raw a quasi-real-life scenario for cosmic data flow and in general for some computing workflows.
NOTE: agreement with Castor@CERN for upgrading the CMS instance of Castor@CERN to 2.1.7-14 version was found for tomorrow, Tuesday, August 12th, 09h00-11h30 CERN time.
