Minutes

## LHCb

- Site is okay and things are working fine.

- Higher failure rates on Piz Daint, not correlated with the type of job, which should be followed up.

- The problem is that Vladimir does not follow up (problem disappears and he does not care anymore). Roland shall speak with Vladimir to try and see what to do.

## ATLAS

- Site looks fine, comparable with LHEP

- arc04 is behaving badly towards SAM tests (jobs work well, though). It will be followed up between ATLAS and CSCS

- Failed WC is high, which needs to be checked (it might be already solved).

- We should have a separate meeting regarding putting ATLAS dCache pools under NGDF (lead by Gianfranco, with Stefano and Pablo).

- Regarding Tapes, Gianfranco will lead the dicsussion with ATLAS but CSCS would like to be involved in the technical discussion (e.g. use Swift instead of S3).

## CMS

- CSCS went down in the classification quite significantly

- Resolve times are good (fast, once start working on the issues) but it takes much longer before that.

- Accounting monitoring issues are still present and makes it difficult to judge how much is being delivered. CSCS plots will show this more precisely.

## CSCS

- Pledge page split for each VO should include % next time (to help see the fair-share effect),

- CSCS should check if Slurm is killing jobs for excessive time, this might explain why LHCb has that many failed pilots

- Pablo to send a doodle for next F2F in January

- Worth checking with Pascuale, who is already running on UserLab for LHC on GPUs, who also has experience in running in JupyterHub

- Follow-up on open tickets in GGUS 132927 and 133787.

- For Tier-0: CMS may face limitation on the firewall on the SWITCH side, good to know in case of trouble
