CERN: Stefan,Antonio,Joel,Krzystof,Federico,Elisa,Zoltan,Mario
Phone: Andrei,Ricardo,Adrià,Matvey
From previous meeting:
News about Request system since last meeting:
Kzysztof: no need for fixes on Request Cleaning Agent, the problem was in Production Cleqaning agent. Now it works fine.
DIRAC/DIRAC WEB:
Andrei: Two patch releases were released yesterday, with few minor fixes. A WMS agent need to be tested
in certification, for ONLINE.
Krzysztof: refactoring of DMS agents (now use ProcessPool), + added some features to transfer agent (unification of scheduer and transfer agent).
Andrei: RSS status agent client code should be included in the Transfer Agent.
Andrei: Proposal on how to submit a github for a bug. A clear indication of the lines the produce the
bug would be helful, also put in the comment if the fix is for a patch or a full release.
Andrei: SSH Grid Engine computing element reintroduced in some sites.
LHCbDIRAC/LHCbDIRAC WEB:
Joel :
- Certification of LHCbDirac v7r2 still on going.
For LHCbDIRAC WEB ntr.
Report form other meetings
Issues the can be discussed in Amsterdam:
Stefan :
- CVMFS installed on all TIER1 sites since today.
- CVMFS deployment in all LCG sites.
- Improvement of SAM and NAGIOS topology tests.
- Opportunity to introduce tools that allow sites to retrieve informations about experiment status.
Maybe resurrecting some old ones: like SiteView (dashboard app).
- metrics to be implemented within this tools.
Andrei : Some doubt on how this can be implemented.
Adria' : Security TEG. RFCproxy going to be reintroduced, LHCbDIRAC will be ready.
Ricardo : News about WMS TEG
https://twiki.cern.ch/twiki/bin/view/LCG/WorkloadManagementTechnicalEvolution
Discussed pilot factories and other possible evolutions.
Elisa : DMS TEG ntr.
------ Reports from developers
Core/Framework:
Federico : XML reports and summaries usage fully implemented.
Joel : Problem with dirac-proxy-init. If a wrong password is issued no message is shown. Decided to change
the output level of the script.
WMS:
Ricardo : Looking for some technique to prevent huge amount of jobs of the same type to be submitted at the same time.
Andrei : Fix to job agent. Problem with the use of machine certificate.
Joel : No possibily to specify a different working directory for a job.
DataManagement:
Elisa : - Improved performance of DataManagement/StorageHistoryAgent. See savannah task #22885 for details.
- When a replica is removed form archive the access flag present in CS is overwritten when the method is instantiated.
- New LcgFileCatalogClient provided with a new faster getReplicas method (getReplicasL). See savannah task #25266 for details.
RSS:
Mario: - SLS sensors for T1 Voxes and CondBD are back to life.
- SLSAgent needs some modifications, it ( sometimes, specially on Fridays ) crashes or hungs. Work on progress.
- Light review with Stephan ( and Raja too ! ) of the SLS sensors. We should sit together an take a closer look.
- RSS ( DIRAC ) bugfixing, bugfixing, ... bugfixing.
- RSS under review by DIRAC guys, plus some LHCbDIRAC guys too.
- MySQLMonkey may be merged with the existing DB modules ( this is purely DIRAC, just for the record ).
- RSS documentation has finally been published.
- Working partially on minor bugfixes spotted by Matvey. The status of the Web part is... unknown.
Stefan ask to know how to use SLS sensors for dirac components.
Federico propose to have a meeting in the near future on this topic.
Production/Transformation:
Federico :
- News about Resurrect step level accounting records - report number of events / run number. See savannah task #16839 for details.
- Discussion with Antonio and Joel on how to deal with dataquality merging agent deployment. It will not tested in certification but
directly in production on a dedicated machine.
Bookkeeping:
Zoltan : - Refactoring of the BKClient code complete.
- Going to add Conddb tags of the RAw to the metadata of the stripping files needed for Swimming working group. The Online have to send
informations about the Conddb of the run.
Webportal
Matvey :
- LHCbDIRAC few changes in request pages.
- Webportal problem at pic going to be fixed.
AOB:
Federico : Proposal on how to organize the development for LHCbDIRAC. See additional link:
