- NTR
- v7r0 series
- Last PRs all merged
- Should install on DIRAC certification with:
- DIRAC v7r0-preX
- DIRACOS v1r0
- WebApp 4.0
- releases.cfg should be modified accordingly
- need to see where's the DB!
- bashrc will need to be re-done, so a fresh installation is needed
- Instructions should go to https://github.com/DIRACGrid/DIRAC/wiki/DIRAC-v7r0
- All Jenkins tests should be updated
Certification process:
- NTR
Weekly development(s) focus
- Tags and MultiProcessor jobs
- Added some fixes for the use of Tag. The use case is for MultiProcessor jobs but the fixes are totally generic
- Discussion points to an "institutionalization" of how to do multiprocessing
- e.g. the "MultiProcessor" tag should be "hidden", or maybe automatically created
- the users should not need to know which tags to set (so maybe change the API, e.g. add a "setMultiProcessor()"?)
- The BDII2CSAgent may also need to be updated to see if tags could be added
- Also added some explanation within the documentation
- should be changed to "how to use tags" in a generic way
- the use cases in there are real
DIRAC: current PRs and tasks being worked on, or topics from Google forum
- Pilot: need to check if PYTHONPATH is set or not, do NOT pick it up
- in this respect, let's not change the bashrc created by dirac-install
AOB
- Next BiLD-Dev meeting will be held in 5 weeks (17 January first meeting of the year)
