3           LCG Operations Weekly Report
 

 

Summary of status and progress of the LCG Operations. This report covers the WLCG activities since the last MB meeting. All daily meeting summaries are available here: https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOperationsMeetings. Some comments to the slides linked from this meeting’s agenda are noted below.

 

Slide 8: Markus Schulz was asked to follow up with the SAM team to understand why not all Experiments show red on their plots when a site has a scheduled downtime affecting them. This was the case for the scheduled PIC site maintenance on 30 March. This situation had been noticed and reported also in a previous case.

Slide 16: Regarding the FTS change of endpoints, Maria Girone agreed to follow up on whether including the version numbers in the aliases of end points is needed in future.

Slide 19: Ian Bird clarified that after the EGEE III project has finished, the CERN Tier 0 will handle the alarms.

 

 

4           gLexec deployment milestones

 

Ian Bird presented a slide, attached to the agenda, summarizing the agreement on gLexec deployment from the last MB meeting. After discussion, it was agreed to define the following milestones:

·         End of May 2010: gLexec deployed at the Tier 0 and Tier 1 sites, except for BNL and NDGF

·         End of July 2010: gLexec deployed at the Tier 0 and all Tier 1 sites (note: NDGF still need confirmation of the need for MUPJs from the Experiments they support)

 

A date will be set for Tier 2 sites once sufficient Tier 1 sites have deployed gLexec. Also, a milestone will be needed for using gLexec once it has been deployed. A correctly working setup of gLexec should first be demonstrated for the Ops VO and then by the Experiments. This should be possible on or before the end of May 2010.

 

 

5          Evolution of storage and data management

 

Ian Bird presented slides, attached to the agenda, summarizing a discussion on evolution of storage and data management. The next step is to hold a 3 day jamboree. The most likely dates discussed during the meeting were 16-18 June. NIKHEF offered to host the jamboree in Amsterdam.

 

In response to a question, Ian Bird confirmed that he would take the lead on preparing the agenda but would be asking for input.

 

 

6          Future LHCC Meetings 

 

 

Ian Bird presented a slide describing a new format for future LHCC meetings. The next meeting with the referees will be on 4 May.  It is likely that the Experiment Computing Coordinators will be asked to attend the LHCC closed session on 6 May in addition to Ian Bird as WLCG Project Leader.

 

 

7          AOB

 

 

In response to a question on planning downtimes, Ian Bird clarified that it is preferable to schedule site maintenance and downtimes at least 3 weeks in advance and to provide information at the Services Coordination meeting as well as to any relevant mailing lists. Sufficient warning of downtimes is preferred over trying to fit in with the scheduled machine stops.

 

The next meeting will be on Tuesday 20 April 2010 (phone meeting).
