We have two new T1 candidates: IHEP (China) and NCBJ (Poland) both initially for the LHCb experiment. Following the WLCG procedure, their presented their plans at the December 2022 Overview Board and the OB endhorsed them as proto-T1. The Management Board should define a set of milestones, in agreement between the T1(s) and the experiment(s) and monitor the ramp up of the proto-T1 to reach maturity as T1, The MB should recommend full T1 status to the OB when all milestones are achieved. Early next year we should start this process. Congratulations to IHEP and NCBJ for completing the first step.
The WLCG study group looking at the evolution/re-definition of the Flat Budget model met on Nov 28. Dave Britton presented a summary of the discussion at the WLCG Overview Board on Dec 8th. The Overview Board agreed with the proposed next steps:
In early 2023 we will have a second meeting to discuss how we will collect those numbers and we will then start the process.
Today we have the following people in the group. We need a contact from DE and NDGF for the next step

We plan to host the traditional pre-CHEP HSF/WLCG workshop on 6-7 May 2023 in Norfolk. We had a good experience with the format of the Adelaide pre-CHEP workshop: 2x 1/2 days between Saturday and Sunday. We plan to repeat the same format and run the workshop possibly on Saturday afternoon and Sunday morning (details to be understood). we identified two topics that we believe would benefit from a joint WLCG and HSF discussion:
We have discussed briefly with the LHC computing coordinators and some of the facilities and everyone was positive about these ideas. We should progress quickly as we need to have more firm ideas about format and content before the end of January (time when the next CHEP bulletin is expected). We should identify soon a few experts from WLCG and HSF to lead the organisation of the scientific program.
Dear Simone,
in the last few years Virgo, the Gravitational-wave experiment at the European Gravitational Observatory in Italy, is extending and upgrading its distributed computing infrastructure in collaboration with the US-based LIGO Scientific Collaboration (and partially with KAGRA, the Japanese observatory), adopting architectures and tools mostly developed and adopted by the HEP community (HTCondor, Rucio, CVMFS,...) and creating a shared computing infrastructure.
In the past years we have been using computing resources at several WLCG sites: besides our “Tier-1” centres at CNAF and CC-IN2P3, PIC, Cyfronet, UCLouvain, Wigner, SURFsara and the NIKHEF Tier-1 have provided dedicated or opportunistic resources to Virgo, and this will grow in the future with the upcoming O4 observational run scheduled to begin in March 2023 and even more with the enhanced sensitivity foreseen for O5 in 2025-2026.
So, in order to enhance our coordination with Computing Centres and other experiment collaborations, we would like to apply for Observer status in the WLCG Collaboration.
I will also add that the Einstein Telescope Collaboration, which is designing the next-generation European Gravitational-wave observatory, is starting to plan for its first organised Mock Data Challenges; waiting for its computing activities to structure themselves, this could also be an informal way of keeping in touch with that community as well.
Thanks,
