Follow-up from previous meetings
- Last BiLD was December 12th
- Last DIRAC certification hackathon on December 5th
- We then had:
- DiracX hackathon: 14th-15th January 2025, CERN https://indico.cern.ch/event/1458873/
- Not only the usual faces! In fact, large-ish participation from CTAO developers.
- Summary of the immediate results in the minutes
- Dirac&Rucio mini-workshop and hackathon: 16th-17th January 2025, CERN https://indico.cern.ch/event/1443765/
- 45 registered participants, about 30 on site. Good participation, with some results coming from the hackathon part
- notes in https://codimd.web.cern.ch/L1Rfoz-JTJiyPqUJuHffWQ?view
- non-formal agreement is to repeat in about a year time
- DiracX hackathon: 14th-15th January 2025, CERN https://indico.cern.ch/event/1458873/
DIRAC communities roundtable
LHCb:
Alexandre+Christophe+Christopher+Vladimir
- Running continuously 250K+ jobs concurrently, with latest v8 version.
- Prepared a
lhcbdiracxinstance (withlhcbdiracxandlhcbdiracx-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.
ILC/Calice/FCC
André
- NTR
EGI
Andrei
- Running smoothly
- fromPreviousMeeting
- Agreed with the Check-In managers:
- Use a client per VO
- Add
wlcg.verclaim to pass token identification on HTCondorCE sites
- Agreed with the Check-In managers:
- 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
- Nothing to report.
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
