SUMMARY:Implementation of EC-Earth 10km Global Coupled ESiWACE Demonstrato
 r and Recent Computational Improvements
DESCRIPTION:Minisymposium\nClimate and Weather\n\nImplementation of EC-Ear
 th 10km Global Coupled ESiWACE Demonstrator and Recent Computational Impro
 vements\n\nSerradell, Castrillo, Acosta\n\nIn the framework of the Centre 
 of Excellence in Simulation of Weather and Climate in Europe (ESiWACE), a 
 ground-breaking configuration for EC-Earth - a European community Earth-Sy
 stem Model – has been developed. In the atmosphere, the horizontal d
 omain is based on a spectral truncation of the atmospheric model (IFS) at 
 T1279 together with 91 vertical levels. The ocean component (NEMO) is run 
 on the so-called ORCA12 tripolar (cartesian) grid at a horizontal resoluti
 on of about 1/12°, with 75 vertical levels. In this talk, we will pres
 ent the work done to develop this configuration, the computational challen
 ges faced and the usage of the Barcelona Supercomputing Center (BSC) perfo
 rmance tools to analyse and profile the code. Finally, we will present som
 e computational improvements regarding code execution and improved I/O man
 agement, currently developed in the Computational Earth Sciences team (CES
 ) to increase the performance of this configuration.
