0. Ongoing Action List
#10918 - Ricardo commented that the installation of certification machine volhcb12 is waiting for the new distribution tools. Machine access procedures are pending Joel's discussions with IT.
#10919 - SLC4 machine upgrade scenario is also being prepared by Joel
#11223 - Direct submission to CREAM CE can now be tested at some sites (using volhcb06 as a GridFTP server for testing)
1. Production Status Report
- Report from the Production meeting
L0HLT stripping ran very smoothly with 50 input files per job (~500 jobs). 115 jobs failed since one of the Tier-1s was outside the mask, as raised by Philippe it would be advantageous for these jobs not to be declared 'Failed'. Stuart suggested writing an LHCb specific optimiser that uses the mask to hold jobs in a checking state as a quick solution. The second point is the observed behaviour with the Standard plugin that seems to bias jobs to all Tier-1s except CERN. Andrei commented that the shares can be updated to resolve this issue.
- DIRAC services ports
Port ranges have been agreed with IT for LHCb VO-boxes in the range 9130 - 9200, a few services are used outside of this range and will be updated.
2. DIRAC Release Update
- v4r20p1-3 releases
L0HLT stripping with Moore was added. The dirac-service script was updated to discover the handler automatically.
3. DIRAC Tasks
- SVN migration
o SVN developer environment
Adri added a twiki to describe the SVN configuration and setup. Ricardo and Adri mentioned SVN was extremely slow outside of CERN (even with externals removed). Joel will investigate this.
o release building and installing scripts
The script to build the externals should be ready by today or tomorrow at the latest. Ricardo mentioned that the installation and setup phases will be separated. The distribution building is also progressing. How to build global tags out of local tags and a global distribution.
o Subsystems migration status
- Framework status
Adri migrated the monitoring and logging systems to the Framework system. The old agents framework module will be removed from SVN.
- DMS status
Andrew will remove all LHCb specific stuff and add an LHCb system DMS.
- Production Management status
Transformation system (core components) will be factored out of the production management system. The production request service is LHCb specific and will remain in LHCbDIRAC.
- LHCbDIRAC status
Stuart conveyed that the LHCbSystem and Workflow (previously WorkflowLib) were migrated to the new structure inside LHCbDIRAC.
- WMS status
Some agents left to be updated.
- Bookkeeping status
Zoltan commented that the BK system is ready. Some additions to the BK are needed to support CondDB / DDDB tags such that there can be a drop down menu in the request page. Zoltan is preparing a list of the other changes to better formulate productions with a stronger coupling to simulation conditions. This will be presented next week.
