SUMMARY:Computational Performance Evaluation of EC-Earth 10km Global Coupl
 ed ESiWACE Demonstrator: Main Conclusions and New Challenges
DESCRIPTION:Minisymposium\n\nComputational Performance Evaluation of EC-Ea
 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 (cartesian) grid at a horizontal resolution of ab
 out 1/12°. In this talk, we will present the computational challenges 
 faced and the usage of the Barcelona Supercomputing Center (BSC) performan
 ce tools to analyze and profile the code. Additionally, we will present so
 me computational improvements regarding code execution and improved I/O ma
 nagement. Finally, a complete benchmarking will be presented to provide mo
 re information about the scalability and main possible bottlenecks of this
  configuration for new pre-exascale machines, providing some conclusions a
 bout this work.\n\nDomain: CS and Math, Emerging Applications, Climate and
  Weather
