Agenda

• Site Report (PF)

  • 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
• Review Action Items
  • feedback about CREAM CE
• 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.
