Swiss Grid Operations Meeting on 2022-10-13 at 14:00

*Next meeting: *



ALPS back online in week 2

Running on Fort only, Gele remains as a test cluster

Several hiccups affecting Bern


no major issue in the past month


no jobs sent for a few days - some workflows re-adjustments at cern - now back full as usual

Problems with the new ARC - asking for LDAP server, but it shouldnít - debug on going

we should agree that LDAP is not used by anybody - to be discussed next Tuesday meeting

do you want to roll back ? Contact Vladimir (if roll back he canít debug)


move to Fort only / Shall we keep Gele open such that also CERN can do tests ?

LHCb can in principle run on ALPS too. As soon as the picture is clear (see LDAP) we will know better

Migration to ALPS

Daint out in 2023

Needed CEPH storage coming end of the month

months/weeks to deliver 100 nodes (48 nodes at the moment need 80 in total)

Ramp up until end of the year , still have a couple of months for final tuning

Because of scale up issues on ALPS, we may run longer than April on Daint

Possible power cuts from government to be expected




T2 Sites reports



  • Troubled month for compute both on LHEP and Ubelix
  • Completed integration of the Tier-2 pledged storage with the NDGF-T1

T3 Sites reports




  • Any news about the negotiations?
  • We should keep in mind that the fee structure is expected to change, so keeping not useful entries in GOCDB might increase the cost
