1.2 Developments :

 

•  The last Bild meeting https://indico.cern.ch/event/1620003/

 

• General feeling that the pace of porting functionalities from DIRAC to diracx is too slow

• The framework is ready for more contributions

• Many PRs stay unmerged for a long time

 

• Project development organization

• Scrum, sprints, user stories, velocities, etc

• More focused, quicker developments

• DIRAC development planning https://indico.cern.ch/event/1620003/

• Coordinated by Alexandre Boyer

• Hope this will help

 

• Daniela showed a prototype for DIRAC/DiracX deployment K8s-free

• Running from containers

• Can be interesting for some installations

• Documentation pending

 

• IN2P3 contributions

• DMS/File Catalog porting:

• Review the DIRAC8 FC

• Make a (single) choice of components

• Experiment with a final monolitic design (performance)

• Make a new FC implementation in DIRAC9

• with contents migration tools

• Design the FC diracx interfaces

• Port the FC from DIRAC to diracx 

• Andrei, Heloise

• Others ?

• Meeting at CC with this focus

• diracx-cwl (Luisa, Natthan, Loris, Stella)

• How to accelerate the diracx WMS full-fledged system ?

2.3. Juno

• First large data processing

• Heavy load on CS, Sandbox service

• Extra CS services launched

• Sandboxes: many jobs rescheduled, some ran twice due to a bug in the JobS state machine (fixed in 8.077) and production managers/shifters aggressively reschedling Failed jobs

• Need for a transformation validation agent
