        HEP-Workloads status 15m

        In the order of arrival

        - CMS  gen-sim, digi, reco for x86/arm  ready and validated

        - Atlas gen_sherpa, sim_mt, reco_mt for x86/arm ready, stable, validation almost done. 

             - Need final feedback from Atlas to confirm the event throughput is the expected one.

        - Alice reco: validation in progress for x86. Selection of the optimal reco configuration ongoing.
             -  arm support available in cvmfs: we can start to build a x86/arm container

        - LHCb: gen-sim x86 ready/validated (unchanged)
           -   x86/arm: servers for the sw build are ready. Expecting updates from LHCb sw developer if the build is possible.
         
        - Belle2: gen-sim--reco x86 ready/validated (unchanged)
              -   x86/arm: servers to attempt ARM build are available for sw developers.

        Summary from WLCG workshop discussion 20m

        A slide of summary was discussed at the WLCG workshop
        https://indico.cern.ch/event/1162261/sessions/459379/attachments/2544500/4387232/06_FacilitiesSummary.pdf
        NB: Both Randy and Domenico were absent at that summary discussion.

        My (Domenico) interpretation of points 1 and 2.

        April 2023: switch from HS06 to HEPscore 
              - normalization factor 1:1
              - ready for x86. N.B. This does not exclude a priory that it can be also ready for ARM!!
              
        Indeed there is interest from several sites to experiment adoption of ARM servers
            - Among others: evaluate performance of ARM vs x86 servers, and power consumption benefit
            - beneficial to expose an HEPscore configuration that can run on ARM&x86
            
        Need checkpoint in 2023 with Alice, LHCb, Belle2 to understand the feasibility/readiness of the x86/arm workload
            - proposal: check the status at the Task force meeting of the Feb 1st
