DiracX hackathon

14 Jan 2025, 09:00 → 15 Jan 2025, 17:30 Europe/Zurich

2/R-014 (CERN)

Alexandre Franck Boyer (CERN), Andrei Tsaregorodtsev (Aix Marseille Univ, CNRS/IN2P3, CPPM, Marseille, France), Chris Burr (CERN), Christophe Haen (CERN), Federico Stagni (CERN)

Prior to the hackathon we expect people to have installed on their laptop the following tools:

• docker
• git
• code editor (e.g. VSCode)
• conda (if you don't just follow the *first code block* of https://dirac.readthedocs.io/en/latest/DeveloperGuide/DevelopmentEnvironment/DeveloperInstallation/editingCode.html#installing-conda)
• Eduroam certificates for people outside CERN

 

Ideally:

• be aware of python type hints (read https://fastapi.tiangolo.com/python-types/ for example)
• followed the FastAPI tutorial: https://fastapi.tiangolo.com/tutorial/

Tasks:

• Mikhailo + Alexandre + Luisa
  • CWL: https://github.com/DIRACGrid/diracx/discussions/175
    • –> Test of the prototype (made by Alexandre) on several different workflows
    • –> Mikhailo is trying to leverage some of the CWL functionalities instead of re-creating them in Dirac
      • through extension of CWL using “hints”, no need to pass extra configuration files
• use httpx instead of requests
  • –> PR open by Max
• Daniela + Federico
  • move GridPP test setup to v9 + DiracX
    • –> Progress, but far from completion. Few bugs found and fixed
• Andrei + Christophe + Bertrand + Federico
  • Move CTA and EGI instance to v9 + DiracX
    • –> trying to make it work with CheckIn, using Dex as intermediate step. Now, trying to check if we can get rid of Dex altogether.
    • installation editable and debuggable
  • Natthan debugging with Christophe, DBs were not being contacted by the VM
• Federico
  • Document migration from Dirac v8 to Dirac V9 + diracx
    • –> few updates
• Volodymir + Maximilian + Christophe
  • Issues from https://github.com/DIRACGrid/diracx-charts/issues
    • use security context for volume
  • Created more issues! :) while using a different cluster
• Janusz + Chris and Chris
  • Restructured the Pilot Logging System – works!
    • new tests not yet working
• Ueda + Cedric
  • updates to B2DIRAC for DIRAC v9
• Cedric (+Christophe +Chris)
  • “admin VO”
    • –> VO can be managed by CERN SSO
    • VOMS2CS for egroup
• Ruslan
  • DiracX extension: trying to update it
