    Table ronde: What ML development is the most appropriate for an IN2P3-wide approach, beyond exchange of experience ?
    
    Does it make sense to push for advancement in Machine Learning on the institute level, or are problems/solutions too specific for each project and lab? What does this mean for the effort on training and recruitement?
    
    Orateur: Yann Coadou (CPPM, Aix-Marseille Université, CNRS/IN2P3)

  Internet of Things — a key topic for IN2P3?
  
  Distributed detectors and control systems are a reality in IN2P3 experiments (accelerators, telescope arrays, KM3NeT,...). What are the possible benefits in a coordinated IoT effort, e.g. in combination with Machine Learning, and shall this be a key element of the perspectives?

    Virtualisation and academic clouds
    
    Virtualisation is not only interesting for small and medium size projects, but also in general a way to preserve and share workflows. Benefits and drawback of academic clouds, such as the ones provided through France Grilles.

    Table ronde: How to better coordinate between the different domains?
    
    Participants: Vincent Breton (LPC), Eric Chassande-Mottin (APC)
    
    Solutions for WLCG and large projects are not necessarily applicable for a wide range of smaller projects within IN2P3. How can we better satisfy the different needs, how should this be coordinated and what should be the focus?
    
    Orateur: Maude LE JEUNE (APC)

    Portability of code
    
    What can be the way forward in using accelerators (GPU, FPGA) and HPC in our field? Is dedicated re-coding necessary, or are abstraction layer libraries like alpaka, kokkos, SYCL the way forward?

    Status and possible impact of Quantum Computing for our sciences

    Table ronde: Emerging technologies — shall we lead or shall we follow?
    
    Participants: Catherine Biscarat (L2IT), Gilles Grasseau (LLR), Bogdan Vulpescu (LPC)
    
    Emerging technologies, like Quantum Computing, provide a large potential but also a great risk. Shall IN2P3 engage actively in these domains as contributor / developer, or rather observe the field and enter as a user in a later stage?

    Open Data: motivation, challenges and solutions
    
    The pressure on the scientific community, to provide open access to data derived in their experiments, is rising (e.g. loi numerique, plan national science ouverte). How do we respond to that, what changes are necessary?

    Software development and quality
    
    WLCG and space projects impose strict quality assurance for developers. What are key points here? What could be the benefit for other, smaller projects to impose standards, rules, etc. Should IN2P3 provide centralised solutions and services in this context?

    Table ronde: Future effort: focused or wide open?
    
    Participants: L. Arrabito (LUPM), F. Derue (LPNHE), E. Ishida (LPC), A. Moller (LPC), P. Verdier (IN2P3)
    
    Throughout the topics (computing model, ML, emerging technologies) a main question is whether we should focus our activities on a few, central projects and topics (WLCG, large astroparticle projects) and find solutions for those, or whether a broader approach should be taken. This is also connected to questions like whether we concentrate our effort to build up and maintain expertise on the lab level, or whether we push stronger for IN2P3-wide solutions, e.g. through stronger reseaux and participation in IN2P3-calcul&données master projects? Is creating expertise-clusters on specific topics in certain labs a way to go forward?
