   * 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.

#ActionItems
---++ Action items
   * CMS has to enable SAM tests for CreamCE
   * Atlas has to check how creamCE behaves and also enable SAM tests.
