Swiss Grid Operations Meeting on 2022-01-13 at 14:00

*Next meeting: 10 Feb. at 14h00



GRAFANA: double check jitter in monitoring plots

Some sites have transfer (rucio) issues with CSCS - being investigated - possible ongoing issue with FTS transfer on kubernetees -provided dCache pools, working on it - see Miguel slides

~80% CPU efficiency for CMS jobs


limiting the #jobs hitting the scratch increases the efficiency. As expected we’re hit on the overall performance. Next increase the #CPU

Unige-BAOBAB work in progress Q1 2022 to increase the 10Gb/sec

From 17.12 very stable running ! see Miguel's slides for more details


Now running straight from Singularity seems to work fine

Miguel CSCS:

Daint: replaced Dell SSD based storage pool with HUAWEI HDD , bigger capacity. This contributed to the stability seen in ATLAS

Current job limits: ATLAS 5000 CPUs CMS 6500 LHCb 3300

Now we can try to increase the #CPU (slightly above pledges to have some margin) ATLAS 7000 CPUs (in two steps of 1000 and check stability ) CMS 7000 LHCb 3300

Mont Fort: no significant progress during the xmas break Alps infrastructures under maintanance
