Minutes:

1- Waiting for final confirmation about running 2 ARCs to the same partition:
   * ATLAS OK (Gianfranco)
   * CMS: OK (Derek confirmed after the meeting)
   * LHCb: OK (Roland confirmed during the meeting)
   * In case of further details the discussion will be continued on SLACK
New configuration expected to be deployed on Feb 10.

2- Logs sharing: Everybody agrees to share the logs

3- Mauro has hard time reconciling the plots provided by ATLAS (Gianfranco) and CSCS (Nick charts).

Nick asked again for the definition of a time interval to define the denominator to be used to produce the charts pledged/delivered core hours. Mauro (and people present agreed) to use a month, such that we are in sync with the OPS meeting.

   Comment by Gianfranco: yes, all ATLAS monthly reports have always been based on calendar month

Mauro: I understand it's not only a matter of integral delivered resources, but also how they are delivered ("flat efficicieny" instead of waves).

On the other hand all present agreed that if CSCS is unable to deliver resources (e.g. security issues) they will try to catch up by temporarily adding some nodes (as they have already done in the past), while if experiments are not sending jobs, those cannot be recovered ("use it or lose it" as if it was on a standard cluster).

Mauro: while the ATLAS message is clear, I don't understand the meaning of the horizontal line "CSCS Pledge 64K" in Gianfranco's slides. It sits at ~105k ?<br /><br />

   Comment by Gianfranco: as discussed in the past, the red line at ~105k on the plot is the combined "federation pledge". As requested in the past, I manually add the text "CSCS Pledge 64K" to quote the each site level of pledge

4- CSCS Nick report

100% availability from WLGC monitoring

slide 3: around 10-14 December ATLAS had no pending jobs. Gianfranco can you check what happened ?<br /><br />   Comment by Gianfranco: No. At the time, no anomalies from ATLAS side. Could not cross-check since CHIPP dashboard was not available (see unresolved slack discussion from 9th to 14th Dec)

Activities in progress:
   * Access to dCache data via Macaroons --&gt;(Edited by Derek) Elia adapted the configuration to allow certificate-less access to the DAV-door. He needed an answer from the CMS central Ops whether they were able to now do macaroon authenticated/authorized transfers. They could, so this is solved.
   * ATLAS DPM Migration: What is the plan and timeline to move from test phase to production? (Gianfranco, sorry couldn't find it in your last report)
  Comment by Gianfranco: https://wiki.chipp.ch/twiki/pub/LCGTier2/MeetingSwissGridOperations20201210/UnibeT2ReportNov2020.pdf<br /><br />

5- CMS:

nothing to report

6- LHCb:

nothing to report (problem transferring files / open ticket should be OK)
