Compte rendu réunion DIRAC@IN2P3
Mercredi 24 juillet 2024
Présents :
Andrei, Bertrand, Natthan, Sorina, Vanessa
Ordre du Jour :
- État du Projet
- Projets
- DiracX
- Publications / Conférences
- Consortium news
- AOB
1. État du Projet
Previous meeting : https://indico.in2p3.fr/event/32911/ - F2F Marseille
1.1 Versions :
- v8.0
-
- v8.0.49, no recent changes
- Prerelease v9.0.a29
-
- No updates since the last hackathon 06.06.2024
1.2 Développements :
- Bild meetings https://demo.hedgedoc.org/UEzgG_9sTlayXBtsoBx6Pg# (link to check)
- Configuration
-
- Large update to remove the use of the Setup everywhere
-
- Systems configuration
-
- Tornado (see below), dips protocols
- OIDC/OAuth2
-
- TokenManager - convert from Tornado https to a "classical" dips service
-
- So, we can skip the use of Tornado https framework for the current v8.0 service
-
- AuthHandler is still in the Tornado framework - needed for authorization with tokens for the Web Portal
-
- We can drop this for the moment
- DiracX
-
- Multiple ongoing developements - see the DUW presentations
-
- Development/testing infrastructure at CC:
-
- cctbdirac01 - v9.0.0a29 dips services
-
- cctbdirac02 - diracx services (with or without K*s)
-
- Experimental REST in the production service
-
- ccdirac07 is installed with v9.0.0a29
-
-
- Idea: run diracx services as part of the EGI DIRAC service
-
-
-
- Use the complex VO as guinea pig for the new REST interface
-
-
-
- No K*s setup
-
- Transformation
- CTA
1.3. Services EGI :
- More or less smooth running, moderate activity
-
- All servers updated to 8.0.49
-
-
- except cccdirac07,08 (see below)
-
- CentOS7 EOL consequences
-
- VOMS services EOL
-
-
- Some stop, some does not
-
-
-
- Rumours are that CNAF is updating VOMS server software for EL9
-
-
-
-
- limited functionality, no VOMS-Admin interface
-
-
-
-
- VOMS support by Check-In is not foreseen.
-
-
- CentOS7 Cloud images can not be used anymore (cvmfs installation fails)
-
-
- Problem with IPHC Cloud, for example
-
-
-
- Tested with Alma9 images
-
-
-
-
- Looks to work
-
-
-
-
-
- We need "yum" images (no Ubuntu/Debian) for the VMs bootstrapping
-
-
-
- Use HTCondorCE SSL authentication methods
-
-
- Looks to work, tested with the CESNET site
-
-
-
- ARC is supposed to still support X509
-
-
-
- Have to comission all the sites for the SSL use
-
- Moving to use tokens for all the EGI VOs
-
- Is dicussed with the Check-In devs/admins
-
- Wenmr, biomed, complex, auger, eiscat.se in the first place
-
-
- Pilot submission only
-
-
- Enable recent Check-In developments in production
-
-
- multi-VO client configuration
-
-
-
- parametric scopes
-
- Registry cleanup
-
- Removing dead VOs and corresponding groups
-
- Remove related users ?
-
- What about "Last seen" timestamp to maintain for users ?
- Site survey is to be done
-
- Grid and Cloud sites
-
- Multiple updates on the sites (EL7 EOL, VOMS, etc)
-
-
- Multiple sites are failing for various reasons
-
-
-
- Nobody will make site comissioning per VO
-
- We have to do it together with the interested VOs
1.4. Européen/Nationaux Projets :
- GreenDIGIT
-
- Site survey to answer
-
- GreenDIGIT workshop colocated with the EGI Conference (Lecce, 30th Sep)
