1. Action Updates
- Action(94) - SystemLoggingDB example
Marcos was checking the FTS error messages and could not find the channel number, to be discussed offline.
- Action(95),(96) - Service Monitoring
Downtime messages were not propagated to the calendar. Philippe suggested that Robeto, Vladimir follow this up. (
ACTION: Robeto, Vladimir)
- Action(109) - Expose DataLogging interface on the web page
Ongoing. This is not yet deployed in production.
- Action(111) - File merging productions
To be discussed later.
- Action(116) - CPU studies
Ongoing.
- Action(122) - Develop specialized SAM Agent to track and report errors with regard to pilots
Ongoing.
- Action(124) - Apply dataset limit check
Ongoing with low priority.
- Action(126) - Document the design of the workflow / production management components
Ongoing.
- Action(132) - Update LFN construction utility to store prod output directories as a parameter
Just have to agree on a parameter to be stored, this is now possible after the recent production API developments.
- Action(133) - RequestDB monitoring
Comments to be sent to Matvey.
- Action(134) - Provide RunDB monitoring page
Ongoing.
- Action(135) - Send accounting from Online DIRAC instance via the gateway to PIC
Andrew installed the updated RunDB on the gateway. The online host should be able to send the accounting records.
- Action(136) - Integrate SAM infrastructure tests
Ongoing.
- Action(137) - Implementing banning specific job types
The job types are now part of the job matching mechanism, action closed.
- Action(138) - Proposal for coping with problematic Tier1 sites absent for long periods during data taking
Andrei updated the twiki page after last week's discussions.
- Action(139) - gLexec testing after deployment at new sites
No new deployment in production available for testing.
- Action(140) - Banning faulty storage elements
Ricardo will circulate the proposal for discussion, Andrew agreed to take this action on board.
2. Production Status Report
- MC'09
For the MC generation
1) Gloria has generate 100 events with high number of pileup and found the CPU to increase linearly with this.
2) Marco is trying to reconstruct these events to find the total CPU time required to produce the events and the total event size.
3) A dummy production has been setup by Stuart (with an old version of Gauss) with the required workflow.
Things remaining to do:
- Wait for the release of the applications next (two) week.
- Ensure the BK entry produced by the MC generation is invisible to users (nothing to do here)
For the MC merging
4) SetupProject has been updated to allow 'SetupProject LHCb' to be performed. This requires a new version of install_project.
5) GaudiApplication was modified to allow the use of new configurables required for merging.
Things remaining to do:
- The new version of install_project which should be tested by Vladimir as soon as possible.
- Ensure the BK entry produced by the MC generation is visible to production system.
- Commission the merging workflow.
- Determine the policy for removing the small DSTs after merging.
- Data distribution policy to be configured for replication of the merged DSTs.
- Update the BK report module to correctly report missing parameters.
3. DIRAC Tasks
- Framework status
Updating pylons to fix the security considerations recently raised by CERN-IT.
- Bookkeeping status
Production lookup and saving of file catalogs is now added to the BK system.
- WMS status
The VOMS server certs. were not correctly updated on the central lxplus Grid UI, Ricardo made an update of the TQ
director to better react to this problem. The updated sandbox service is being prepared.
- DMS status
Mostly bug fixes. LFC admin interface was added to the client.
- Production Management status
Production request page should be tested after groups and new group properties are defined.
- VO-boxes
No update.
- Web Portal
Matvey mentioned that several pages are to be created for the data management. A refurbished site summary page
is now available in production.
- Services deployment ( hardware, configuration )
No response from the hardware request made over a month ago.
4. AOB
The recent downtime cases will be investigated. Recent analysis jobs to ScotGrid are queued, this is no problem.
There are minutes attached to this event.
Show them.
