/CMS Collaboration
The landscape of computing power available for the CMS experiment is rapidly evolving, from a scenario dominated by x86 processors deployed at WLCG sites towards a more diverse mixture of Grid, HPC, and Cloud facilities, incorporating a higher fraction of non-CPU components such as GPUs. Using these facilities heterogeneous resources efficiently to process the vast amounts of data to be collected in the LHC Run3 and beyond, is key to CMS achieving its scientific goals. [...]
