On Zoom: Daniela, Simon, Hideki, Ueda, Natthan, Andrei, Jorge, Vladimir, Alexey, Cedric
Apologies:
Follow-up from previous meetings
- Last BiLD was December 12th
- Last DIRAC certification hackathon on December 5th
- We then had:
DIRAC communities roundtable
LHCb:
Alexandre+Christophe+Christopher+Vladimir
- Running continuously 250K+ jobs concurrently, with latest v8 version.
- Prepared a
lhcbdiracx instance (with lhcbdiracx and lhcbdiracx-web), starting to run tests there
- After going into production, we will release v9+0.1
- Running a stress test (a “ping” from the pilots)
- Accounting issues in using tokens for ARC6 CEs. Suggestion is to wait for ARC7 sites.

- Running smoothly
- fromPreviousMeeting
- Agreed with the Check-In managers:
- Use a client per VO
- Add
wlcg.ver claim to pass token identification on HTCondorCE sites
- Instructions are sent to HTCondorCE sites to configure the SCITOKENS authentication for most popular DIRAC VOs
- Managed to run OpenSearch, small fix incoming with PR
- fromPreviousMeeting
- Setting up the diracx test system with K3S in parallel with DIRAC 9.0. It uses external MySQL and ES servers. Work in progress, the installation becomes functional, still more understanding/configuration needed (DEX, cert-manager).
- Authentication is set up for several VOs to demonstrate multi-IdP/Multi-VO case, works. Used Check-In-dev, wlcg.cloud.cnaf.infn.it, in the pipeline production Check-In, dteam-auth.cern.ch
- Set up Gitlab based DiracX configuration management (CS, values)
Belle2
Hideki
- fromPreviousMeeting Some sites are not compartible with the bundled proxy when using SSHCE and python3. Hideki will open an issue.
- Issue was opened, should be SOLVED
GridPP:
Daniela, Simon, Janusz
CTAO
Natthan, Luisa
- Moved on the Diracv9 configuration
- Some issues:
- issue with dex IdP (can we run without it?)
- issue not related to diracx but currently problem with nginx controller "path type error with
/.well-known"
- “Empty cartesian product” error in SiteDirector
