Workshop introduction & goals
- Jamie Shiers
09:00 - 09:15
<UL> <LI>To understand the state of {site, experiment, service} readiness for data taking {cosmics, pp collisions} according to the current LHC schedule; <LI>To identify the key outstanding issues and associated milestones; <LI>To understand experiment activities {'dress rehearsals', cosmics runs in November/December 2007, March 2008, pp from Spring/Summer on}. </UL>

11:00 - 11:45
Room: Theatre Suggested topics to seed discussion: <UL> <LI>State of hardware resources for startup compared with pledges. Longer term planning - readiness for future major expansion (2010 and beyond). <LI>Tested readiness of magnetic tape infrastructure. <LI>Tested readiness of site data management layer above the hardware including for full rate multi-VO operation. <LI>Formal planning for 24 by 7 operations ready (including for staffing) and documented to the experiments and other sites. <LI>Experiment local site support in place with clearly defined roles. <LI>Other issues you would like to add/clarify/replace. </UL>

Room: Theatre Experiences from sites/experiments operating the FTS servers Deployment of 'residual' (data management) services: <UL> <LI>SRM v2.2 <LI>FTS 2.0, gFal, lcg_utils </UL> Where are we with respect to the plan established in July? Update on the schedule, status of testing, plans for immediate future, milestones etc.

13:30 - 15:30
Room: OakBay Some suggestions raised at the WLCG Management Board are listed below: <UL> <LI>I.Fisk asked for the correlation between “availability as seen via SAM” vs. the “real jobs success rates of the Experiments (via Crab, Ganga, etc)”. <LI>H.Marten suggested that at the Operation Workshop at CHEP the sites should have the top 5 issues for each service. <LI>I.Fisk also suggested a session for feedback from the sites to the developers, in order to improve the services and the software developed. <LI>R.Tafirout suggested that sites should share solutions; sometimes the information is known by others but not easily accessible. </UL> Other topics: <OL> <LI>Results of review of CERN service deployment wrt resilience to glitches / common service interventions <LI>What do we need to operate the WLCG service for LHC data taking? <LI>Cross site problem determination <LI>Top middleware and operations issues <LI>Implications of migration to LSF 7 </OL>
User Support BOF - Torsten Antoni (FZK)
User Support BOF
- Torsten Antoni (FZK)
13:30 - 15:30
Room: Sannich The aim of the User Support BOF is to better understand what the VO expect from the WLCG/EGEE support infrastructure and how they interact with it, in order to improve the processes and workflows and to make the EGEE user support more helpful for the VO-users. This is a follow-up and continuation of the User Support Workshop held in Karlsruhe in March 2007. http://indico.cern.ch/conferenceDisplay.py?confId=11905 The latest developments in the EGEE/WLCG user support will be presented. Updates from the VOs about their support infrastructure are of course welcome.

Concurrent data export and archiving tests
11:30 - 12:30
We still need to show that we can write data to mass storage and export it to all Tier1s and the full nominal rates for all VOs concurrently. This session will discuss the requirements and schedule for such an exercise.
