 ECMWF is engaged in partnerships with its Member State organisations, academia, national HPC centres and hardware vendors to prepare for the extreme-scale challenge, in terms of both computing and data handling. The programme explores advanced developments
 of numerical methods, algorithms, programming models and workflows to substantially enhance efficiency and scalability of the entire forecasting system on future HPC architectures.<o:p></o:p></p>
