1. Project Status
Partial budget received (75%)
- Missions (DUW'26, Prague)
- DUW organization (cattering, etc)
- Try to avoid participation fees

- Minor (authdb, sandbox optimization)
1.2 DiracX Hackathon (24-25 March)
Less participation than usual, dominated by French participants :)
Main news
- First introduction of the diracx tasks
- Main stumbling block on the way of DIRAC->diracx migration
- Replacement for
- Agents, Executors, RMS
- Database+Logic+Tasks+Routers+Testing
- Well documented
- Can be exercised locally
- pixi environment
- Very useful for everybody interested in the diracx migration development - you are welcome to follow it
- CWL based WMS is advancing (Alexandre, Ryan, Natthan, Luisa, ...)
- Close to be released ?...
- Web interface updates
- Some change in the choice of the underlying libraries
- Next DIRAC Hackathon
- Date to be fixed - preliminarily end of June
1.3 Current Developments :
- The last Ddev meeting https://indico.cern.ch/event/1668571/
- Sprints (Natthan, Luisa, Stella, Loris, Heloise, Mazen)
- Heloise, Loris: Sprint related to the RSS
- IN2P3 contributions
- DMS/File Catalog porting (Andrei, Heloise, Bertrand ? )
- Goal: come up with the single configuration, best performing based on the acquired experience
- To be used in DIRAC9
- To be used as the starting point for the diracx migration
- Testing 3 FileCatalog DB schemas
- Currently used by default (split tables, DirectoryLevelTree)
- "Consolidated" (merged tables, DirectoryLevelTree)
- "LHCb" (merged tables, DirectoryClosure)
- Metadata support to be confirmed, updates might be needed
- 3 File Catalog services are set up per DB schema
- Performance Tests :
- Population
- using client server communication
- same script for all the schemas
- filling in about 1M files/100K directories with metadata
- ~4hours
- Queries
- Simple look-ups in parallel
- Various bulk queries - to be defined
- Status
- Services and databases are defined:
- Might need some optimization
- Population scripts are ready
- Adding about 70files/sec in a single thread
- Some minor improvements might be need
- Population test can be done this week
- Query tests can start afterwards
- Procedure to migrate current catalogs to be defined
- Better data consistency (Foreign Keys, less tables)
- Optimizations based on the LHCb and other's experience
- Directory usage
- Some plug-ins can still be there
- E.g. Multi-VO metadata
- diracx-cwl (Luisa, Natthan, Loris, Stella)
- How to accelerate the diracx WMS full-fledged system ?
- Status
- Deployment with K8s (Bertrand)
- Status
- Opensearch
- Common prefix a tous les indexes
- Utilisation des certificats
- Utilisation des certificats
- Still way to be found for the case with multiple databases
