        • HEP-SCORE Task Force: Helge Meinhard stepped down from the coordination of the Task Force as he moved to different duties. Thanks to Helge for the excellent work in driving the Task Force towards its final stage. Domenico Giordano and Randy Sobie took over the coordination, with the full suppor of the Task Force members. 
        • Andrea Valassi is stepping down as secretary of the WLCG Management Board as he has been appinted secretary of the CRSG. Congratulations to Andrea V. and thanks for all the support he provided to the MB over many years. Andrea Sciaba agreed to take over the role of WLCG MB secretary. Thanks to Andrea S.  
        • At the June 2022 MB we discussed the appointment of the WLCG Software Liaisons for the next year and we opened a call for suggestions. We received little input and we solicit more input from the MB members and the key stakeholders (including CERN EP-SFT and the HSF). The role is now published in the WLCG website as suggested by the MB members: https://wlcg.web.cern.ch/activities/liaison/software



      • Flat Budget and Hardware Cost 1m
        Speaker: Simone Campana (CERN)

        In the process of resource requests to the C-RRB (through the CRSG recommendations) and subsequent commitments from the funding agencies (the "pledging" process) we often incur two issues/challenges, mostly due to the definition of "flat budget". In the "flat budget" scenario we expect to be able to deploy ~15% more CPU, disk and tape every year for the same budget. The two issues are: 

        * The 15% figure is an estimate from the CERN procurement experience. Some countries reported recurrently that the situation might vary from this baseline considerably and the CERN numbers are generally an optimistic scenario. It would be good to be able to know how much that difference is IN AVERAGE TERMS, without exposing in the details the costs of various hardware types in the single countries

        * The computing model of the experiments would benefit from more flexibility in the definition of flat budget. A given experiment for example might need more that a 15% increase in CPU for the following year and less than a 15% increase for disk and/or tape. There is currently no indication of the comparative costs of resources and therefore it is not easy to judge how compatible a similar request would be with respect to a flat budget. Having this information would facilitate the discussions at the RRB and provide useful knowledge. Again, the CERN numbers could be used as a starting point, but a more general indication again on AVERAGE TERMS including other countries would be best

        WLCG had a Cost Model working group in the past that looked at some of those details and produced a report. A high level of precision is not needed here, but rather some general indications and trends, with updated information. While it is not appropriate to agree or disagree today on this, it would be good to collect a first round of opinions from the MB and follow up at the next meeting with a more structured discussion. 

      • Token-based authentication timeline 1m
        Speakers: Maarten Litmaath (CERN), Simone Campana (CERN)

        The WLCG authorisation working group has been working on a new timeline for token based AAI rollout based on the massive progress in the last 2 years and the acquired experience. A draft document is in preparation and should be available to the Management Board in the next 10 days. We will invite the MB to make suggestions or recommendations via email. The endorsement of the plan will be important to secure the proper effort in the areas of interest.
