Many scientific codes are being restructured (modernized), optimized and ported to run efficiently on the emerging hybrid-node architectures, eventually with different typologies of accelerators. Exascale is also posing challenges on code scalability, load balance, fault tolerance, and co-design among others.

Exascale is not only about applications and capability runs, but entails also workflow managers (orchestrators) and huge amounts of data streams and processes (eventually involving artificial intelligence), from decentralized edge (sensor level) computing, HPC applications (centralized or cloud-based) to the final post-processed results collided to the end- user.

This session will consider the current state and the transition of European computational geosciences. Which are the emerging perspectives, bottlenecks and challenges in geosciences and geohazards and HPC services for a safer world (hazards and operational services).

Which is the EuroHPC deployment roadmap, policy and HPC infrastructure access modes? Which are the research funding opportunities for geosciences from Horizon Europe (REA) or other EC Directorates-General (DGs)? How can European geoscientists better partner to benefit from the Exascale transition opportunities?
