Follow-up from previous meeting
- GS DOCS: google evaluating students. We got a few applications and selected 2. News at the end of the month
- Closed several WebApp issues that are now in v4r0
DIRAC communities roundtable
- CLIC:
- moved to v6r21
- LHCb:
- NTR
- CTA:
- moved to v6r20 recently
- new DB for provenance (postgresSQL), using sqlAlchemy for connecting to it. Had to install a python module (could be added in DIRACOS extension when available)
- not registered as a catalog
- GridPP:
- Trying to connect DIRAC to Openstack cloud (questions on the forum)
- Running v6r21p7
- EGI
- Running smoothly, and starting to use OAuth authentication, with some patches directly in production.
- Incorporating new cloud resources, need to incorporate properly Pilot3 in the cloud
- Belle2:
- Moved to v6r21
- Juno:
- deploying production system (TS) and data movement (with TS)
- queries done by the InputDataAgent to the DFC may become very slow (e.g. 800K files returned, way too much)
- not many technical solutions, need to find an operational way around it
- next week planning to upgrade to v6r21
