Swiss Grid Operations Meeting on 2020-12-10 at 14:00

Minutes:

CSCS report (the only one uploaded)

WLCH SAM: 100% availability and reliability
CHIPP pledge delivery: 111.3 %
- shared as 41% ATLAS ; 33% CMS ; 26% LHCb
Reminder: during xmas break Piz Daint maintenance is on best effort - no monitoring
ARC CE state counts is now in the dashboard (Nov 25)
ARC CE Log Access:
- Hardware received, configuration underway
- All three experiments need to explicitly agree to share this data between each other and this needs to be on record
  - Nick wants the confirmation that by making the log available we’re not breaking any confidentiality agreement
  - (ATLAS/CMS members cannot have certificates for both experiments for confidentiality reasons)
  - --> Gianfranco / Derek is that OK ?
CMS dCache Access:
- Access to dCache data via Macaroons
  - Waiting on some feedbac
  - —> Derek
- ATLAS DPM Migration:
  - Convert part of dCache to DPM
  - Test in progress, need plan for making production
  - —> Gianfranco

Validation of accounting data:
- Khours vs KHS06 Hours Accounting Discrepancy:
  - BDII and ARC configuration seem correct
    - Requested assistance from Julia, no response
    - Ticket in the process of being opened to request assistance
    - —> Mauro fwd Dmitrios contact

Overlapping ARC CEs
- One Slurm partition served by 2 ARC CEs
- If this is an OK configuration, then go ahead during the February 10th maintenance
- —> Gianfranco: Can we get an example configuration?
- this would improve the 2 ARCs unbalance we have today

NEXT MEETING 21 JANUARY 2021 @ 14h00 - Let me know if that is not OK for you
