Presentation of the topics

Parallel sessions

International roadmapping effort

This session is dedicated to exchange regional roadmapping effort in AI/HPC/Quantum convergence.

GenAI and software engineering

Several questions will be adressed under this topic:

  1. Software heritage: an opportunity for digital resilience, sovereignty and reference data set for advance AI model training
  2. AI acceleration of development cycles
  3. Profiling oracles: AI-driven analysis to identify bottlenecks
  4. Trace-based learnings: collect structured traces to optimise partitioning and scheduling
  5. Trust and benchmarking: audit and validation of AI-generated HPC code / GenAI impact on training young generation

Experimenting large AI models for science, "1000 scientists AI Jam"

This session will be dedicated to share experiences from the US and Japan, initiate a European AI Jam and work on possible plans for international collaborations (for instance: Tri-Million Parameter Consortium – TPC)

HPC/AI convergence

This session will adress the following subjects:

  1. Model updates
  2. Training/inference at scale
  3. Data generation
  4. Drift monitoring
  5. Co-design

The following questions will be addressed:

  1. Co-design: Algorithms and architectures for transformers / foundation models
  2. Scalability: Memory limits, heterogeneous architecture, slow interconnects and low-precision
  3. Distributed learning: Train on inherently distributed data (simulation traces)
  4. Sovereignty: Build-vs-buy for European AI-HPC stack
  5. Data: Access, open models vs open data, PB-scale science datasets

Computing continuum

This session aims to continue the work started at InPEx 2025 aiming to build a representative picture of relevant active regional and international use cases of interest to explore expectations, design and effective implementation of computing continuum components.

During the previous sessions, each use case proposed challenges/roadblockers and initial approaches to tackle them. To help identifying commonalities, all use-case representatives have been requested to comment on the criteria identified and potentially propose new criteria if relevant.

Among the studied use cases we can mention:

  1. The Square Kilometer Array (SKA), a workflow-intensive project that would benefit significantly from operating across multiple infrastructures;
  2. High-energy physics (HEP) use cases;
  3. EsiWACE – a high-performance climate and weather benchmark;
  4. Urgent computing: facilitating trade-off management on the Edge – Cloud Computing Continuum for Urgent Science;
  5. Micro-meteorology control;
  6. Disaster digital twins.

This new session aims to complete the picture with other relevant use cases and additional challenges, to build an updated view on major existing projects addressing these challenges and to discuss on concrete operational steps to enable international collaborations in this area. The ideal outcome of the session is a solid updated vision on the aforementioned topics at an international level, which can serve as a basis for upcoming roadmapping documents and funding strategies.
