SUMMARY:Towards the New Generation of Earth System Models: Challenges on t
 he Road to Exascale
DESCRIPTION:Minisymposium\n\nThe path towards exascale computing holds eno
 rmous challenges for the community of weather and climate modelling regard
 ing portability, scalability and data management. Exascale machines will a
 llow running Global kilometre-resolving simulations which eventually will 
 enable the representation of features impossible until now. However, the n
 ew complexity of the Earth System Models (ESMs) on development could be cr
 itical for the new exascale's deployment. \nSpeakers from the HPC-driven E
 uropean centre of excellence ESiWACE on exascale computing for weather and
  climate models will address this matter from different points of view; ea
 ch speaker will present different challenges faced in their scientific dom
 ain and the approaches to mitigate these challenges. Including topics such
  as 1) the latest results and technical achievements in the context of ESi
 WACE 2) the computational analysis of the O(1km) global model and challeng
 es presented on the development of the new configurations, 3) the use of P
 Syclone in LFRic to achieve performance and portability on different archi
 tectures and accelerators such as GPUs or 4) the new coupling generation f
 or ESMs on exascale platforms through OASIS3-MCT. All of them pursuing the
  main goal to prepare the weather and climate community to be able to make
  use of exascale systems when they become available.\n\nLFRic and PSyclone
 : Meeting Challenges on the Road to Exascale\n\nKavcic\n\nLFRic is the new
  weather and climate modelling system being developed by the UK Met Office
  to replace the existing Unified Model in preparation for exascale computi
 ng in the 2020s. The design of the supporting infrastructure follows objec
 t-oriented principles to facilitate modularity and the use of ...\n\n-----
 ----------------\nESiWACE: Towards Storm Resolving Global Weather and Clim
 ate Simulations\n\nBiercamp\n\nTo provide answers and mitigation pathways 
 with respect to climate change we need a new generation of weather and cli
 mate models, which can directly resolve clouds and storms. Such Storm
  and Cloud Resolving Models will only become possible with Exascale Comput
 ing. This new type of models will b...\n\n---------------------\nBenchmark
 ing Coupling Software Regridding Functionality: One of the Challenges of C
 ode Coupling in Climate Modelling\n\nValcke, Piacentini, Jonville\n\nChall
 enges facing coupling software of the climate modelling community will be 
 presented, building on discussions of the 5th Workshop on Coupling Technol
 ogies for Earth System Models that took place virtually in September 2020.
  In particular, the benchmarking work around the analysis of the quality .

 rth 10km Global Coupled ESiWACE Demonstrator: Main Conclusions and New Cha
 llenges\n\nAcosta\n\nIn the framework of the ESiWACE2, a ground-breaking c
 onfiguration for EC-Earth is on development. In the atmosphere, 
 the horizontal domain is based on a spectral truncation of the atmospheric
  model (IFS) at T1279 together. The ocean component (NEMO) is run on the s
 o-called ORCA12 tripolar ...\n\n\nDomain: CS and Math, Emerging Applicatio
