Agenda
- Site Report (PF)
- Workaround two Lustre issues, so stability has greatly improved.
- No much activity last days, probably because ICHEP is ongoing
- Andrej Filipcic requested 500 max jobs in ARC Frontend. We put 200 for now
- Moab deployed after observing Maui problems, it's under evaluation
- Marc report about Atlas tests

- AOB
Attendants
- ATLAS: Marc
- CMS: Derek, Leo
- LHCb:
- CSCS: Fotis, Pablo
Minutes
- Marc presented a test he did with around 800 jobs on three different sites: CSCS, Lyon and CERN.
- part of them creating libraries and the other short analysis.
- The efficiency and time-to-run at CSCS is very good. Lyon comes afterwards, and Cern takes a lot of time to start
- Cern is also very quick finishing the jobs, when they don't fail
- CSCS was almost empty at that moment, we have to see in the next tests
- Possible improvements: increase the length of the job, some work left to distinguish between the two type of jobs
- CreamCE Feedback
- CMS. Jobs are flowing, and Leo sees no difference between lcg-ce and cream-ce so far. Still SAM tests are not enabled
- Atlas: Marc didn't check.
Action items
- CMS has to enable SAM tests for CreamCE
- Atlas has to check how creamCE behaves and also enable SAM tests.
