   * CSCS:
   * CMS:
   * ATLAS: Gianfranco
   * LHCb: Roland

---++ Minutes
   * LHCb
      * Some tickets get never resolved because the problem goes away
      * ACTION: Roland shall try to follow up next time it happens
      * ACTION: CSCS should plug in the Nagios tests from LHCb to get the input from the SAM tests (to keep the site green, otherwise LHCb does not care much)

   * ATLAS
      * ACTION: CSCS should check if the hammercloud queues go offline notification email arrives.
      * End-of-November is where the issues focus (ATLAS could not follow up)
      * arc04 looks red since end-of-November. Nagios checks (if imported into our nagios) should have shown it... but it was not reported either (it only affects A/R metrics)
      * ACTION: Fair-share needs to be looked at (some details needed in the next meetings)
      * ACTION: We should make sure we do the monthly operatoins meetings, even if we have F2F meetings
      * There are fluctuations in performance, most probably GPFS around December. This also shows clear in the ATLAS IO workloads.
      * ACTION: CSCS should follow up. ATLAS can try to check different IO mechanisms (direct-IO and/or usage of local disks)

   * CMS
      * Pledge delivery looks very bad: part of it is coming from lack of information on the CMS side, but there is also a part (which shows in the CSCS charts) is related to CSCS compute: it looks like either the queue pressure is not sufficient or the fairshare might be wong.

   * UNIBE
      * Hardening the monitoring has paid back with lower failure rates

---++ Other Action items
   * all VO representatives shall evaluate the needs of the VOs for the next 4 years in terms of CPU, DISK, TAPE, ratios…
      * also whether the increase over the years should be continuous or not
   * CSCS shall make a statement on what part of phoenix and on what timescale will be available to CHIPP for re-usage.
      * Bern hopes for 50% of the PHOENIX hardware in 2019.
      * Other VOs shall make a statement what they want from HW.
   * clarify pledges numbers; and prepare 2019 pledges to be entered in Sep. 2018 including LHConCRAY growth of 27% (use 25% ?) CPU and 15% storage.
   * Objection raised by ATLAS to changing the CPU shares from 40:40:20 to 37.5:37.5:25 without a clear mandate by the CHIPP CB. ATLAS will consider 40:40:20 effective share (despite wrong pledges in REBUS) until a decision to change this will be taken and announced with a protocol.
   * A CPU and disk growth plan by ATLAS (part of the decision to move to the Cray platform) has been presented. This is based on the agreed growth rates of 27% and 15% storage. The ATLAS number show slightly different ratios for CPU and disk that should be clarified before any change to the batch shares are implemented.
   * The other VOs have been asked to pur forward similar plans.
