SUMMARY:MS1F - Energy Efficiency and Carbon Footprint of Earth System Mode
 ling in Times of Spiraling Electricity Prices and Net-Zero Goals
DESCRIPTION:Minisymposium\n\nRising energy costs and the endeavor to reach
  net-zero have recently brought energy-efficient high-performance computin
 g back to the forefront. In no application area is this topic more pressin
 g than in Earth system modeling (ESM), which comes at a huge computational
  expense and where there is a strong moral prerogative to minimize its neg
 ative impact. Atmospheric models progress towards cloud-resolving scales r
 equiring Exascale computing while electricity becomes more scarce. Computi
 ng centers are being challenged by rising energy budgets while transitioni
 ng to dramatically more powerful high-performance computing platforms. Are
  the ESM and HPC communities doing enough to address these challenges? We 
 have invited four speakers to talk about a wide range of energy and climat
 e footprint perspectives, ranging from the tools needed for energy consump
 tion analysis, to the concrete carbon footprint analysis of high-resolutio
 n global simulations on a state-of-the-art computing platform, and finally
  to the societal obligation we face in our community to lead as role model
 s. While we can highlight our best efforts towards energy efficiency and c
 arbon prudence, we will leave it to the audience to decide if we are livin
 g up to our obligation to the planet while still promoting this important 
 research area.\n\nThe Energy Efficiency and Carbon Footprint of ICON Clima
 te Model Simulations at CSCS\n\nIn an environmental impact case study of c
 omputing at the Swiss National Supercomputing Center (CSCS) we consider th
 e energy consumption of climate simulations currently planned on the new C
 SCS "Alps" computing platform. We use the Icosahedral Non-hydrostatic (ICO
 N) model, which has been extensively...\n\n\nWilliam Sawyer (ETH Zurich / 
 CSCS)\n---------------------\nEnergy Efficiency Analysis and Optimization 
 for Present and Future, Possibly Heterogenous, HPC Systems\n\nThis talk is
  split into a summary of the work at DKRZ on the energy efficiency of the 
 present supercomputer Levante and first insights from testing modular clim
 ate simulations on state-of-the-art hardware. A first overview covers job 
 performance monitoring, energy measurement infrastructure and iden...\n\n\
 nPay Giesselmann (DKRZ)\n---------------------\nWalking the Walk: The ESM 
 Community must be a Role Model in Energy Efficiency\n\nRecently, in the fa
 ce of mounting concern about climate change, the energy demand (and carbon
  footprint) of rapidly growing IT tech, such as cloud, cryptocurrencies, a
 nd generative AI has come under increasing scrutiny. Compared to these glo
 bal IT trends, the carbon emissions of earth system modelli...\n\n\nRichar

 ure\n\nThe Swiss National Supercomputing Centre (CSCS) is expanding its co
 mputational capabilities with the Alps architecture, a Cray HPE EX system 
 incorporating around 5000 GH200 modules, in addition to the pre-existing n
 odes. This expansion poses challenges in monitoring due to hardware hetero
 geneity, in...\n\n\nJean-Guillaume Piccinali and Jonathan Coles (ETH Zuric
